2 FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER TR STADLER TR firewood hot water central heating boilers provide comfortable and energy saving heating. Such heating is enabled with integration of the new innovative technology in the field of control and modern production technology. s are constructed for burning all types of wood and reach efficiencies of over 91%. Constant growth of fossil fuel prices and the increased care for the environment make this boiler even more important. By using different types of wood, even of different humidity, these boilers allow you to reach perfect combustion conditions. Emitted flue gases are harmless to the natural balance. You should load the boiler with ½ m long firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. Fireplace volume equals to 150 l and can be loaded with up to 50kg of hardwood logs. Connection to the power supply is very simple, as the boiler includes already prepared wiring with plug equipped cables. By purchasing our boiler, you meet all of the requirements to obtain your government's subsidy. Construction of the boiler incorporated the modern degassing combustion technology. The flame is vertically directed through the burner nozzle with the help of the controlled injection of the primary and secondary air. When the flame enters the combustion chamber, it swirls and in touch with the red-hot combustion chamber causes the remaining not-combusted wood gases to burn at temperatures of approx C. The control regulates the operation of the primary and secondary air step motors, thus supplying the combustion process with regulated quantities of air which enable the best combustion. The large panel shielded loading place protects the boiler from accumulation of tar and ensures long service life of the boiler. s can be loaded with firewood of up to 56 cm in length. The burner nozzle is made of chrome alloy which also significantly prolongs the service life of the boiler. 2 The boiler is included in the German BafA-List and therefore entitled to incentives. The fireproof clay combustion chamber is upgraded with the bottom made of high-temperature resistant concrete which guarantees complete combustion of wood gases. s are equipped with the Lambda probe, temperature sensor and continuously controlled electric motor of the fan.

6 FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER GT STADLER GT boilers belong to a new generation of firewood hot water heating boilers. With their wood gasification technology they enable modern and energy saving heating. They are constructed to burn all types of firewood of up to 54 cm or 33cm in length. Their combustion efficiency reaches over 90%. themselfs are designed and produced in Slovenia. By naming the product range STADLER we wished to show that the production is still active and adapts to new combustion conditions and techniques. These boilers provide stable combustion processes enabled by the inovative construction and lambda probe. They achieve excellent combustion parameters which are characteristic for wood gasification boilers. Quality production, controlled combustion process and high efficiency of these boilers beat the competition of the lower priced boilers by far. By using different types of wood, it is possible to achieve good combustion conditions in the boiler. Firewood burns in the lower part, whilst the supplied primary air leads the flame and wood gases downwards into the combustion chamber. When flue gases come through the burner nozzle, they are blown with controlled supply of secondary air. Flue gases mixed with the flame and fresh air swirl in the combustion chamber, and in touch with the red-hot fireproof clay, burn with extreme temperatures. The control regulates the combustion process via lambda probe and the temperature sensor in the chimney and sensors installed in the boiler and the accumulator. It also regulates the continuous control of the fan and the primary and secondary combustion air supply motor flap. Controlled supply of the combustion air enables low values of emmissions in flue gases which are significantly lower than the law regulated ones. s are equipped with an insulated hot combustion chamber made of fireproof clay which quickly reaches high temperatures and enables good combustion of wood gases. The efficiency boilers reache over 90% which points out the top-class echievement. The hot combustion chamber enables the boiler to reach the optimal combustion process in only minutes. These boilers must be installed into systems equipped with hot water accumulators. We recommend the use of the heating system control because this is the only way to preserve different water layers in the hot water accumulator. Our boilers are in compliance with all currently valid provisions on safety and construction design (e.g. DIN 4751 B1.1, DIN 4702, etc.). They are tested for pressure and water tightness, factory equipped with a thermal protection device and can be installed in closed heating systems. The permissible operating pressure of boilers equals to 3 bars. We recommend the use of firewood with humidity between 15 and 25% which is achieved by drying it outdoors for 2 years. You should load the boiler with firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. The volume of the fireplace is 105 dm3 and can be loaded with approx. 30 kg of firewood. You should load the container with firewood to the top of the doors, while taking care not to load them too close to each other as this could cause jamming. The boiler is included in the German BafA-List and therefore entitled to incentives.

7 WOOD PELLET HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER PELET STAR Stadler PELET STAR hot water central heating boilers belong to a new generation of wood pellet boilers. They were designed by our company in cooperation with the Swedish company Ariterm. The BeQuem burner enabled the development of a completely automatic wood pellet boiler which guarantees reliable and safe operation with minimum cleaning and maintenance interventions. s are produced with the modern sheet metal treatment technique. Construction concepts provided the boiler with a touch of modern design, while respecting the ergonomic demands for the operation of the boiler. Construction of the boiler is produced in accordance with regulations DIN 4751 B1.1, DIN 4702, EN s are equipped with the CE 0036 marking and can also be installed in smaller rooms to provide comfortable and energy saving heating. The side of the boiler is equipped with the weekly wood pellet silo, whilst the large ash chamber allows longer intervals between cleaning. Construction of boilers allows easy access to all internal surfaces and hence easier cleaning and maintenance. We recommend you to install your central heating system with a hot water accumulator which allows optimum boiler operation with low energy consumption (low-energy constructions and transition periods). In case of bigger consumption, the hot water accumulator amortizes the current lower burner operation capacity. Special construction of the BeQuem wood pellet burner allows reliable operation and high level of safety. Wood pellet feeding is arranged with a double stoker system where the lower stoker feeds wood pellets into the lower part of the combustion chamber. With such wood pellet feeding the ash is pushed further and the combustion chamber automatically cleaned. Such feeding technique makes the burner appropriate even with wood pellets of weaker quality which can now often be found on the market. Fire safety is ensured with temperature sensors and the cell block. Ignition and control of the flame are controlled with a special sensor.

9 WOOD PELLET HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER EKO PELET Stadler EKO PELET hot water central heating boilers were designed with combination of firewood boilers and Swedish made burners. In this way boilers with the BeQuem wood pellet burners became automated units for heating of living quarters. Unlike the use of fossil fuels, the use of local energy resources, such as wood pellets, is harmless to the environment and decreases heating costs. These wood pellet boilers are equipped with a control which allows completely automated operation of the boiler without constant regulation. They regulate the supply of pellets from the container and the combustion process. s are also equipped with a pellet ignition device and flame control. The burner activates automatically as soon as the sensor in the boiler detects fall of water temperature bellow the preset value, and deactivates as soon as this temperature is reached. The volume of the factory offered wood pellet container equals to 0.6 m3 which is enough for approx. 10 days of operation. Alternatively you can order a larger container with volume of 0,93 m3. Our company also offers elements for the construction of even larger wood pellet containers which can be assembled in your boiler room or the room next to it. These boilers can easily be rearranged into firewood heating boilers by unscrewing the flange screws, removing the burner and turning it into the position which does not interfere with the operation of the boiler. Then, you have to install the cover over the burner on the external side of the boiler. Fix the cover firmly and prevent the flue gases from escaping. Cleaning of the boiler is also very simple. Open the lower door and remove the ash collected in the drawer. From time to time it is also necessary to check if the combustion chamber is clean. In case you notice any slag residue, remove it adequately. We do not recommend you to disassemble the burner during cleaning, however if this is necessary please call our authorised repair service centre. After each rearrangement of the boiler for burning firewood, clean the fireplace of the boiler and the space under the grate. The construction of the burner is equipped with a display showing mode of operation and temperature. Under the display, there are some arrow keys which enable you to scroll along the simple menu. With the use of these keys you can set the operation of the burner or simply control its operation. Calculation of the required boiler power m 2 cm 0,30 Apartment x Living quarters x Heat loss size height coefficient Poorly insulated buildings, shady and high altitude positions require the use of a heat loss coefficient of In case of simpler heating systems we recommend you to install a special pump. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C and then only emits the excess energy into the system. During the cool down phase, the pump and the three-way valve ensure that the water temperature in the boiler does not fall below 55 C, thus preventing the formation of condensate. If the system includes a hot water accumulator, the three-way mixing valve allows the accumulator to be filled. With the use of the water accumulator, better operation can be achieved, especially during transition periods when temperatures are not too low. model Wood pellet boiler capacity kw Firewood boiler capacity kw / 860 = Required boiler power Electric connection 240 V 50 Hz Power consumption 240 V 50 Hz Efficiency EKO PELET W 60 W 91,5 % EKO PELET W 90 W 90,7 % WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, Tel.: , Fax: , wvterm@wvterm.si 9

They can easily be rearranged into firewood heating boilers by unscrewing the flange screws connecting the burner and the boiler, removing the burner and turning it into the position which does not interfere with the operation of the boiler and its safe loading. Then, you have to install the cover over the burner on the external side of the boiler. Fix the cover firmly and prevent the flue gases from escaping. Fasten the line of the draft regulator to the primary air flap of the lower door. Remove the safety barrier and the rectifier from the boiler. After you finish the above procedure, the boiler is rearranged to use firewood. CHARACTERISTICS OF FIREWOOD BOILERS: Stadler EKO hot water central heating boilers are constructed to burn 33 cm long firewood (logs are to be loaded transversely) and 56 cm long firewood (logs are to be loaded longitudinally to the boiler). They are intended for operation in the 90/70 C mode. The new way of flue gas conduction improves combustion processes during the burning of firewood. Loading doors enable loading of large logs. Constructions of boilers are produced in accordance with regulations DIN 4751 B1.1, DIN 4702 and EN s are also equipped with the CE 0036 marking. Chimney must be constructed in accordance with solid fuel boiler chimney manufacturer's tables and must ensure drafts as described in the table of the brochure related to individual boiler models. s are equipped with large fireplaces, therefore we recommend you to burn your wood pellets or firewood in a downwards direction, thus prolonging the combustion time of a single load. During the burning phase, the draft regulator must constantly be set above 70 C, thus preventing overcooling of the return water and formation of condensate in the fireplace. We also recommend the installation of one of the insufficient water return prevention systems. Easy access to all internal surfaces enables easy cleaning and maintenance.

11 HOT WATER CENTRAL HEATING ACCUMULATORS MODEL: AT Hot water accumulators represent intermediate central heating elements and are used in modern heating systems. They are used for accumulation of the excess thermal energy produced by the boiler and for evenly regulated supply of energy to different consumers. Hot water accumulators are indispensable in systems with installed firewood, wood pellet, or wood chip heating boilers. Firewood heating boilers do not allow the complete control of power without significant interruption of the combustion process. Firewood combustion cycle brings excess thermal energy which consumers cannot use at that moment therefore it is conducted to the hot water accumulator. After the fuel has burnt and the heating elements cooled down, the automatic control takes care for transfer of hot water from the accumulator to heating elements. Our production programme includes hot water accumulators of various sizes: 500, 750, 1000, 1250, 1500, 1800, 2000, and 3000l. Accumulators are equipped with fittings for connection of heating circles, sensors and thermometers. The number of used fittings depends on the complexity of the planned heating system prescribed by the manufacturer at the time of sale of the product or by other professional subjects.

16 DUAL FIREPLACE FIREWOOD AND FUEL OIL CENTRAL HEATING BOILERS MODEL: STADLER TOBI Stadler TOBI central heating boilers are constructed as extremely energy saving boilers due to the installation of fuel oil and firewood boilers in a single construction. Both boilers use a single water reservoir, but completely separated fireplaces. Such design enables automatic rearrangement from burning of one type of fuel to another which cannot be achieved with combined boilers. s are basically intended for burning firewood in the 90/70 C operating mode. The fuel oil part of the boiler activates automatically after all of the fuel from the firewood fireplace has been used and the temperature dropped under the preset value. The fuel oil part of the boiler does not activate if the firewood fireplace is full and the preset temperature is reached. In case you deactivate the automatic system, these boilers only operate by burning firewood. A more modern construction concept classifies these boilers among the new generation of eco-friendly products as they operate in a similar way as hybrid cars. The firewood fireplace is equipped with modern burning in the lower side part of the boiler which enables controlled long burning process lasting even over 3 ½ h. The fireplace allows you to burn 33 cm long firewood. s are equipped with a return water preheating system and a cast iron grate which improves firewood combustion processes. Loading doors allow loading of large pieces of firewood. The special fireplace constructed for burning fuel oil is equipped with a hot combustion chamber and a turbulator in the third draft. Its design enables top-class efficiency of over 93%. Combusted flue gas emissions reach even more favourable parameters than required by law. The fuel oil part of the boiler is equipped with the SELTRON control. These boilers cannot be upgrades with domestic water heaters. Domestic water heaters can be installed as separated units which are then connected to the boiler. Ba purchasing the domestic water heater additionally, it is possible to control the temperature in the domestic water heater with the help of a pump. panelling is enamelled in the RAL 3000 or RAL 2004 colour combination. Our boilers are in compliance with all regulations regarding safety at work. Construction of the boiler is produced in accordance with regulations DIN 4751 B1.1, DIN 4702, EN 303-5, and is equipped with the CE 0036 marking. s are also equipped with a thermal protection device. The central heating system must compulsory include one of the system for lifting the return water as this is the only way to use the boiler with lower powers. If the boiler is not connected with the system for lifting return water the boiler condensates and causes poor combustion. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C, and emits only the excess energy into the system. At the same time it prevents the return water with temperatures lower than 55 C to enter the boiler, thus preventing the condensation. If the system includes a hot water accumulator, the three-way mixing valve enables the accumulator to be filled. With the use of the hot water accumulator, better operation of the burning device can be achieved, especially during the transition periods when temperatures are not too low, but still demand heating. model TOBI Power (fuel oil) kw Power (wood) kw Fireplace size dm 3 water quantity l Required draft Pa Weight kg Chimney Connection (fuel oil) Ø Chimney Connection (wood) Ø width mm height mm Required door width to enter the boiler with panelling into the room Required door width to enter the boiler without panelling into the room Efficiency (fuel oil) ,2 81, ,4 81,5 % Efficiency (wood) % 16 WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, tel.: , Fax: , wvterm@wvterm.si

27 Model Heating power kw power kw Weight kg BIOFLAMM HEATING SYSTEMS MODEL: TRB/VA This heating device comprises the pre-fireplace reactor TRB and the VA boiler. The combination of these two components is used everywhere where the combustion conditions are difficult due to the higher humidity or due to the problematic fuel. Bioflamm multi draft VA boilers are used as heat exchangers and places for flue gas burn down. s are equipped with two horizontal drafts and three vertical drafts routed through the pipe packages. The inspection-cleaning doors are positioned on the side of the boiler (top, bottom) and on the back side, thus allowing easy access. In especially tough operating conditions boilers are shielded with quality fireproof clay in the first draft. Large dimensioned drafts and vertical pipe packages provide this heat exchanger with low temperature flue gases and enable high efficiency. All larger boilers are equipped with walkable platforms with railings intended for cleaning and supply and with entrance and exit ladder. They are produced by welding certified quality sheet metal in accordance with DIN 4702 and The construction is made in accordance with TRD and all regulations and norms of SIST, EN-DIN and VGB. The production process is controlled by our experts as the company is certified in accordance with ISO 9001, module B and module D. Products are equipped with the CE 0036 marking. The standard version of boilers operates with overpressure of 3 bars and the operating temperature of the flow of 120 C. On special demand, boilers can also be produced for operation in tougher conditions (hot water boilers or low pressure steam boilers with powers of up to 6 MW, temperatures 140 C and operating pressure 4.5 bars). The automatic Bioflamm TRB pre-fireplaces with movable grates and automatic deashing enable the combustion of very problematic fuels. Reactors are constructed as a water-cooled pipe cage construction. The frame of the burner is shielded with quality fireproof clay A 40 or A 60, depending on the fuel the device is planned for. The quality movable transverse grates made of 24% chromed alloy ensure long service life and quality combustion on grates. Grates are installed next to each other, are simple, can be individually replaced, and form several movable grate layers. In case of extra humid, ash rich, or slag forming fuels, the Bioflamm degassing reactors with special air injection systems improve the combustion with their controlled combustion air fans. The primary air fan regulates the degassing process on the grate, whilst the secondary air fan enables combustion during the degassing of the formed flue gases. Separation from the fireplace and the boiler enables fast control in accordance with DIN 4751 Part 2. Reactors are produced in two construction versions; TRB N for humid fuels and TRB T for dry fuels. They are also equipped with the automatic cleaning and ash removing system. The exterior of the boiler can be installed with automatic deashing which transfers the ash into the ash container. The standard version of boilers operates with overpressure of 3 bars and the operating temperature of the flow of 120 C. On special demand, boilers can also be produced for operation in tougher conditions (hot water boilers with powers of up to 6 MW, temperatures 140 C and operating pressure 4.5 bars). In the past years, the company also developed an extra version of reactors marked TRB LK for connection of grain dryers or dryers of the sawdust accumulated during wood pellet production. Reactors are made of double-walled steel sheet frame where the air is directed into individual combustion zones. On the internal side, reactors are shielded with fireproof clay, whilst their external side is substantially insulated to prevent heat radiation into the environment. Grate movements and combustion air injection are similar to those of the basic version. The entire TRB/VA device is controlled by the Optimatika+ micro processing control via information received from the Lambda probe and temperature sensors. This control regulates the combustion process as well as the peripheral units from the takeover of the wood mass from the silo all to the cleaning of flue gases. The standard scope of micro processing control delivery includes the system for calling of 6 telephone numbers in case of standstill of any component of the device.

31 DEVICE CONTROL Controls with the Lambda probe Lambdamatika and Optimatika+ are installed in Rital cabinets which include all control elements for the entire system, continuous motor drives, protection of drive units, and the device for calling of 6 telephone numbers. On special order they can also be installed with modems for connection with the remote control. The cabinet is equipped with the main switch (depending on the supply power of electric motors) and the emergency switch. Doors of the cabinet are equipped with the microprocessor with a display and a keyboard for direct access into the combustion parameter setting program. Use of the program and the input of desired data is simple as the program allows scrolling with cursor keys and includes simple commands. The programme is made as a multi-level programme device operator level and repair or fine-tune expert level. VISUALIZATION The communication package for remote control of data and for the visualization of operation is used for control when the operator is out of the boiler room. The connection is established with the help of the modem and internet, or directly via the cable in case of small distances. In case of the cable connection, the visualization works trouble-free for 24 h, but demands an amplifier in case of distances greater than 200 m. Long-term connection via your telephone will cause disturbances during monitoring of current values due to the signal strength fluctuation. Significant data about device operation and reports of disturbances can be followed on the PC display. This way enables the operator-supervisor the access to all required data, which is why he can quickly react in cases of device malfunctioning. On the basis of these data, the supervisor makes corrective measures and adapts the operation to desired parameters. If the supervisor is unable to repair the malfunctioning he must immediately contact the manufacturer's service team which will take care for it with no major problems. With the permission of the investor, the manufacturer's service team can enter into the communication system. The visualization allows access to different levels of operation, depending on the data to be checked. All levels enable formation of excel charts and analyses of operation in individual time periods. Because this is a complex heating device, we recommend the operator to plan adequate maintenance interventions on the basis of number of hours of operation. COMPANY PRESENTATION OUR 150 YEARS Company WVterm from Maribor continues the TVT Boris Kidrič company's tradition in the field of boiler production. The beginning of industrial production reaches back in 1863 when the railway carriage and steam locomotive overhaul facilities were constructed. In 1970 the TVT Boris Kidrič, proizvodnja tirnih in cestnih vozil company signed a contract with the German STADLER company. Later, TVT became the biggest producer of boilers in the former Yugoslavia. Unfortunately, this big company could not avoid the crisis which appeared after the break-up of Yugoslavia. In 1995 an ownership transformation occurred and a new company WVterm was founded. During the past years, WVterm proved to be a vital export oriented company. The changed approach to work enabled better conditions in all fields of operation. The operation economics provides the company with a favourable business partner position. The company experienced rapid growth during the past years and today employs approx. 80 workers instead of the original 27. Due to the local conditions, export orientation was compulsory and today represents over 60% of all production. Our biggest partners come from the EU market. Besides the EU market the company is also present in the markets of the former Yugoslavia where the TAM STADLER trademark is still appreciated. Our perspective is built on experience upgraded with hard development work and with the aim to develop good products interesting for the market. With the internal and external potentials we significantly renewed and expanded our production programme. Efficiencies as well as low flue gas emissions and design of our products are now at the same level as the European competition. The conformity of products is guaranteed with the company s TÜV certificates which represent an integral part of documentation. One of the founding aims of the market appearance is to renew the old trademark that is to establish a positive contact with the market. We strive to restore the good name of the STADLER TVT trademark with hard work and quality production. Use of the trademark is protected both at home and abroad with number Z Besides this trademark we are also present in the wood biomass market with Bioflamm and HDG Bavaria trademarks. The company provides HDG boilers in Slovenia and other countries of the former Yugoslavia. Company's production programme is very wide and with its Made in Slovenija products covers almost all areas of hot water boiler production. In the last years, the company increasingly invested in new technologies and has already caught up with technical development of its European competitors, thus keeping its competitiveness in the EU. During the last years, the welding technology was modernised with new pulse welding machines and robot welding of boilers and components. Preparation of boiler parts is based on top-class laser cutting of sheet metal and CNC technology for sheet metal and pipe forming. This technology helped us to achieve the production and productivity which is comparable with European competitors. WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, Tel.: , Fax: , wvterm@wvterm.si 31

74 FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER TR STADLER TR firewood hot water central heating boilers provide comfortable and energy saving heating. Such heating is enabled with integration of the new innovative technology in the field of control and modern production technology. s are constructed for burning all types of wood and reach efficiencies of over 91%. Constant growth of fossil fuel prices and the increased care for the environment make this boiler even more important. By using different types of wood, even of different humidity, these boilers allow you to reach perfect combustion conditions. Emitted flue gases are harmless to the natural balance. You should load the boiler with ½ m long firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. Fireplace volume equals to 150 l and can be loaded with up to 50kg of hardwood logs. Connection to the power supply is very simple, as the boiler includes already prepared wiring with plug equipped cables. By purchasing our boiler, you meet all of the requirements to obtain your government's subsidy. Construction of the boiler incorporated the modern degassing combustion technology. The flame is vertically directed through the burner nozzle with the help of the controlled injection of the primary and secondary air. When the flame enters the combustion chamber, it swirls and in touch with the red-hot combustion chamber causes the remaining not-combusted wood gases to burn at temperatures of approx C. The control regulates the operation of the primary and secondary air step motors, thus supplying the combustion process with regulated quantities of air which enable the best combustion. The large panel shielded loading place protects the boiler from accumulation of tar and ensures long service life of the boiler. s can be loaded with firewood of up to 56 cm in length. The burner nozzle is made of chrome alloy which also significantly prolongs the service life of the boiler. 2 The fireproof clay combustion chamber is upgraded with the bottom made of high-temperature resistant concrete which guarantees complete combustion of wood gases. s are equipped with the Lambda probe, temperature sensor and continuously controlled electric motor of the fan.

76 FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER LT Due to their wood gas combustion technology, Stadler LT firewood hot water central heating boilers enable energy saving heating. s are constructed for burning all types of wood and reach efficiencies of over 90%. They are completely made in Slovenia, thus showing high level of expertise. Development of the product brought such improvement that our company was granted with the national patent by the Slovenian Intellectual Property Office. These hot water boilers are constructed for for burning of 56 cm, or 33 cm long firewood. You should load the boiler with firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. Fireplace volume equals to 130 dm3 and can be loaded with approx. 35 kg of firewood. The container should be loaded with firewood to its top limit, while taking care not to load the firewood too close to each other as this could cause jamming. Modern control enables you to burn different types of wood and to reach ideal combustion conditions with flue gases which are harmless to the natural balance. These boilers are equipped with modern fireplaces with hot combustion chambers made of temperature resistant ceramics. The hot combustion chamber allows swirling combustion of wood gases resulting in the combustion of all combustible substances in flue gases.

78 FIREWOOD HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER GT STADLER GT boilers belong to a new generation of firewood hot water heating boilers. With their wood gasification technology they enable modern and energy saving heating. They are constructed to burn all types of firewood of up to 54 cm or 33cm in length. Their combustion efficiency reaches over 90%. themselfs are designed and produced in Slovenia. By naming the product range STADLER we wished to show that the production is still active and adapts to new combustion conditions and techniques. In comparison with our boilers marked TR and LT, these boilers come with a simpler control. Nevertheless, they provide stable combustion processes enabled by the inovative construction. These boilers achieve excellent combustion parameters which are characteristic for wood gasification boilers. Quality production, controlled combustion process and high efficiency of these boilers beat the competition of the lower priced boilers by far. By using different types of wood, it is possible to achieve good combustion conditions in the boiler. Firewood burns in the lower part, whilst the supplied primary air leads the flame and wood gases downwards into the combustion chamber. When flue gases come through the burner nozzle, they are blown with controlled supply of secondary air. Flue gases mixed with the flame and fresh air swirl in the combustion chamber, and in touch with the red-hot fireproof clay, burn with extreme temperatures. The control regulates the combustion process via the temperature sensor in the chimney and sensors installed in the boiler and the accumulator. It also regulates the continuous control of the fan and the primary and secondary combustion air supply motor flap. Controlled supply of the combustion air enables low values of emmissions in flue gases which are significantly lower than the law regulated ones. s are equipped with an insulated hot combustion chamber made of fireproof clay which quickly reaches high temperatures and enables good combustion of wood gases. The efficiency boilers reache over 90% which points out the top-class echievement for boilers with lower level control without the Lambda probe. The hot combustion chamber enables the boiler to reach the optimal combustion Characteristics Unit GT 20 GT 30 process in only minutes. These boilers can be installed into systems equipped with hot water accumulators. We recommend the use of the heating system control because this is the only way to preserve different water layers in the hot water accumulator. Our boilers are in compliance with all currently valid provisions on safety and construction design (e.g. DIN 4751 B1.1, DIN 4702, etc.). They are tested for pressure and water tightness, factory equipped with a thermal protection device and can be installed in closed heating systems. The permissible operating pressure of boilers equals to 3 bars. We recommend the use of firewood with humidity of 25% which is achieved by drying it outdoors for 2 years. You should load the boiler with firewood as close together as possible, thus reaching uniform fuel structure and stable combustion conditions. Single load should be enough for several hours of operation. The volume of the fireplace is 105 dm3 and can be loaded with approx. 30 kg of firewood. You should load the container with firewood to the top of the doors, while taking care not to load them too close to each other as this could cause jamming.

81 WOOD PELLET HOT WATER CENTRAL HEATING BOILERS MODEL: STADLER EKO PELET Stadler EKO PELET hot water central heating boilers were designed with combination of firewood boilers and Swedish made burners. In this way boilers with the BeQuem wood pellet burners became automated units for heating of living quarters. Unlike the use of fossil fuels, the use of local energy resources, such as wood pellets, is harmless to the environment and decreases heating costs. These wood pellet boilers are equipped with a control which allows completely automated operation of the boiler without constant regulation. They regulate the supply of pellets from the container and the combustion process. s are also equipped with a pellet ignition device and flame control. The burner activates automatically as soon as the sensor in the boiler detects fall of water temperature bellow the preset value, and deactivates as soon as this temperature is reached. The volume of the factory offered wood pellet container equals to 0.6 m3 which is enough for approx. 10 days of operation. Alternatively you can order a larger container with volume of 0,93 m3. Our company also offers elements for the construction of even larger wood pellet containers which can be assembled in your boiler room or the room next to it. These boilers can easily be rearranged into firewood heating boilers by unscrewing the flange screws, removing the burner and turning it into the position which does not interfere with the operation of the boiler. Then, you have to install the cover over the burner on the external side of the boiler. Fix the cover firmly and prevent the flue gases from escaping. Cleaning of the boiler is also very simple. Open the lower door and remove the ash collected in the drawer. From time to time it is also necessary to check if the combustion chamber is clean. In case you notice any slag residue, remove it adequately. We do not recommend you to disassemble the burner during cleaning, however if this is necessary please call our authorised repair service centre. After each rearrangement of the boiler for burning firewood, clean the fireplace of the boiler and the space under the grate. The construction of the burner is equipped with a display showing mode of operation and temperature. Under the display, there are some arrow keys which enable you to scroll along the simple menu. With the use of these keys you can set the operation of the burner or simply control its operation. Calculation of the required boiler power m 2 cm 0,30 Apartment x Living quarters x Heat loss size height coefficient Poorly insulated buildings, shady and high altitude positions require the use of a heat loss coefficient of In case of simpler heating systems we recommend you to install a special pump. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C and then only emits the excess energy into the system. During the cool down phase, the pump and the three-way valve ensure that the water temperature in the boiler does not fall below 55 C, thus preventing the formation of condensate. If the system includes a hot water accumulator, the three-way mixing valve allows the accumulator to be filled. With the use of the water accumulator, better operation can be achieved, especially during transition periods when temperatures are not too low. model Wood pellet boiler capacity kw Firewood boiler capacity kw / 860 = Required boiler power Electric connection 240 V 50 Hz Power consumption 240 V 50 Hz Efficiency EKO PELET W 60 W 91,5 % EKO PELET W 90 W 90,7 % WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, Tel.: , Fax: , wvterm@wvterm.si 9

83 HOT WATER CENTRAL HEATING ACCUMULATORS MODEL: AT Hot water accumulators represent intermediate central heating elements and are used in modern heating systems. They are used for accumulation of the excess thermal energy produced by the boiler and for evenly regulated supply of energy to different consumers. Hot water accumulators are indispensable in systems with installed firewood, wood pellet, or wood chip heating boilers. Firewood heating boilers do not allow the complete control of power without significant interruption of the combustion process. Firewood combustion cycle brings excess thermal energy which consumers cannot use at that moment therefore it is conducted to the hot water accumulator. After the fuel has burnt and the heating elements cooled down, the automatic control takes care for transfer of hot water from the accumulator to heating elements. Our production programme includes hot water accumulators of various sizes: 500, 750, 1000, 1250, 1500, 1800, 2000, and 3000l.

Construction of the boiler is produced in accordance with regulations DIN 4751 B1.1, DIN 4702, EN 303-5, and is equipped with the CE 0036 marking. s are also equipped with a thermal protection device. The central heating system must compulsory include one of the system for lifting the return water as this is the only way to use the boiler with lower powers. If the boiler is not connected with the system for lifting return water the boiler condensates and causes poor combustion. This special pump with a three-way valve ensures that the boiler first reaches the temperature of 60 C, and emits only the excess energy into the system. At the same time it prevents the return water with temperatures lower than 55 C to enter the boiler, thus preventing the condensation. If the system includes a hot water accumulator, the three-way mixing valve enables the accumulator to be filled. With the use of the hot water accumulator, better operation of the burning device can be achieved, especially during the transition periods when temperatures are not too low, but still demand heating. model TOBI Power (fuel oil) kw Power (wood) kw Fireplace size dm 3 water quantity l Required draft Pa Weight kg Chimney Connection (fuel oil) Ø Chimney Connection (wood) Ø width mm height mm Required door width to enter the boiler with panelling into the room Required door width to enter the boiler without panelling into the room Efficiency (fuel oil) ,2 81, ,4 81,5 % Efficiency (wood) % 16 WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, tel.: , Fax: , wvterm@wvterm.si

103 DEVICE CONTROL Controls with the Lambda probe Lambdamatika and Optimatika+ are installed in Rital cabinets which include all control elements for the entire system, continuous motor drives, protection of drive units, and the device for calling of 6 telephone numbers. On special order they can also be installed with modems for connection with the remote control. The cabinet is equipped with the main switch (depending on the supply power of electric motors) and the emergency switch. Doors of the cabinet are equipped with the microprocessor with a display and a keyboard for direct access into the combustion parameter setting program. Use of the program and the input of desired data is simple as the program allows scrolling with cursor keys and includes simple commands. The programme is made as a multi-level programme device operator level and repair or fine-tune expert level. VISUALIZATION The communication package for remote control of data and for the visualization of operation is used for control when the operator is out of the boiler room. The connection is established with the help of the modem and internet, or directly via the cable in case of small distances. In case of the cable connection, the visualization works trouble-free for 24 h, but demands an amplifier in case of distances greater than 200 m. Long-term connection via your telephone will cause disturbances during monitoring of current values due to the signal strength fluctuation. Significant data about device operation and reports of disturbances can be followed on the PC display. This way enables the operator-supervisor the access to all required data, which is why he can quickly react in cases of device malfunctioning. On the basis of these data, the supervisor makes corrective measures and adapts the operation to desired parameters. If the supervisor is unable to repair the malfunctioning he must immediately contact the manufacturer's service team which will take care for it with no major problems. With the permission of the investor, the manufacturer's service team can enter into the communication system. The visualization allows access to different levels of operation, depending on the data to be checked. All levels enable formation of excel charts and analyses of operation in individual time periods. Because this is a complex heating device, we recommend the operator to plan adequate maintenance interventions on the basis of number of hours of operation. COMPANY PRESENTATION OUR 150 YEARS Company WVterm from Maribor continues the TVT Boris Kidrič company's tradition in the field of boiler production. The beginning of industrial production reaches back in 1863 when the railway carriage and steam locomotive overhaul facilities were constructed. In 1970 the TVT Boris Kidrič, proizvodnja tirnih in cestnih vozil company signed a contract with the German STADLER company. Later, TVT became the biggest producer of boilers in the former Yugoslavia. Unfortunately, this big company could not avoid the crisis which appeared after the break-up of Yugoslavia. In 1995 an ownership transformation occurred and a new company WVterm was founded. During the past years, WVterm proved to be a vital export oriented company. The changed approach to work enabled better conditions in all fields of operation. The operation economics provides the company with a favourable business partner position. The company experienced rapid growth during the past years and today employs approx. 80 workers instead of the original 27. Due to the local conditions, export orientation was compulsory and today represents over 60% of all production. Our biggest partners come from the EU market. Besides the EU market the company is also present in the markets of the former Yugoslavia where the TAM STADLER trademark is still appreciated. Our perspective is built on experience upgraded with hard development work and with the aim to develop good products interesting for the market. With the internal and external potentials we significantly renewed and expanded our production programme. Efficiencies as well as low flue gas emissions and design of our products are now at the same level as the European competition. The conformity of products is guaranteed with the company s TÜV certificates which represent an integral part of documentation. One of the founding aims of the market appearance is to renew the old trademark that is to establish a positive contact with the market. We strive to restore the good name of the STADLER TVT trademark with hard work and quality production. Use of the trademark is protected both at home and abroad with number Z Besides this trademark we are also present in the wood biomass market with Bioflamm and HDG Bavaria trademarks. The company provides HDG boilers in Slovenia and other countries of the former Yugoslavia. Company's production programme is very wide and with its Made in Slovenija products covers almost all areas of hot water boiler production. In the last years, the company increasingly invested in new technologies and has already caught up with technical development of its European competitors, thus keeping its competitiveness in the EU. During the last years, the welding technology was modernised with new pulse welding machines and robot welding of boilers and components. Preparation of boiler parts is based on top-class laser cutting of sheet metal and CNC technology for sheet metal and pipe forming. This technology helped us to achieve the production and productivity which is comparable with European competitors. WVterm d.o.o., Valvasorjeva 73, 2000 Maribor, Tel.: , Fax: , wvterm@wvterm.si 31
