3 2/3 Heating with wood the most natural fuel in the world The rising cost of fossil fuel and growing environmental awareness are resulting in an ever-increasing demand for renewable forms of energy. On the following pages, we will provide you with comprehensive information about how to burn wood, which is a regenerative fuel, efficiently in advanced boilers. A wood boiler is a good alternative to heating with oil or gas. Alongside environmental considerations there are also economic reasons for relying on wood, which, as an indigenous fuel is very cost effective and not subject to wide price fluctuations. Thanks to the advanced Viessmann technology heating with wood is now both efficient and convenient. Whether you are looking for an auxiliary appliance or a complete heating system, the Viessmann range offers flexible solutions, fired with logs or pellets subject to boiler type.

6 Introduction

7 6/7 Saving energy and protecting the climate Viessmann is aware of its responsibility for the sustained protection of the environment. Its company philosophy and products have been developed with this duty in mind. "Nothing is so good that it cannot be improved". This maxim is also reflected in our company principles. In its industry, Viessmann can rightfully claim to be the leader in quality and technology, and as such, aims to continually set new standards. Of course, this applies in particular to the company's product range, which is consistently geared towards significantly lowering the consumption of fossil fuels and gradually replacing them with renewable sources of energy. At around 40 percent, the heating market actually accounts for the largest proportion of energy consumption. The rest is shared by "goods transport", "personal transport" and "power", with 20 percent each. These values also fairly accurately apply to other industrial countries. Ever-rising energy costs mean that the emphasis is on reducing the consumption of fossil fuels as quickly as possible. Wood is a good alternative Taking the overall investment and current energy prices into consideration, a wood burning heating system is an economical alternative. Viessmann wood boilers are highly efficient and economical in their fuel consumption. Extending an existing heating system with a wood boiler significantly reduces spending on oil and gas, and will start paying for itself in next to no time. You will be making a positive contribution towards the sustained protection of our climate, as heating with wood is CO 2 neutral. This means that only as much carbon dioxide is released into the atmosphere as the wood absorbed while it was growing. Viessmann has the right solution for you, too! Viessmann offers energy efficient heating systems for oil, gas, solar, biomass and natural heat. The pictographs are designed to aid orientation when selecting a system. Viessmann works continually to develop new, environmentally responsible solutions, resulting in environmentally sound, cost effective and efficient heating systems.

8 What you should know about wood and pellets Wood storage The combustion of moist wood is not only uneconomical, it can also lead to high emissions and tar deposits inside the chimney stack due to low combustion temperatures. Wood reaches its highest calorific value after being dried for several years in a well protected place. Here are a few tips: Split round logs with a diameter of 10 cm or more Stack the logs in a ventilated and preferably sunny spot underneath a rain canopy If possible, stack logs with generous air gaps to enable flowing air to absorb the dissipating moisture Stack logs on a support timber so moist air can escape Never store freshly cut wood in a cellar, as air and sunshine are required for drying. However, dry wood can be stored in ventilated cellars Pellet properties 100 percent natural wood remnants are used to produce pellets compliant with DIN-Plus or ÖNorm. This raw material is waste matter created by the wood processing industry in large volumes through planing or sawing. Fine-grained wood remnants are compressed under high pressure and formed into pellets, i.e. pressed into a cylindrical shape. The fuel is stored and transported in perfectly dry conditions. Absolutely dry storage must also be ensured by the system user. Optimum and effective combustion can only be ensured under these conditions. Pellets are offered in packs and in bulk. In their loose form, pellets are transported by silo tanker and pumped into the storage room via a hose system. If an oil heating system is to be completely replaced by a new pellet heating system, the room in the cellar that was previously used to store fuel oil is ideally suited for this purpose. Pellets are the ideal fuel: futureproof, inexpensive, easy to store and CO 2 neutral.

14 Wood gasification boiler Vitoligno 200-S 20 to 40 kw The Vitoligno 200-S biomass boiler is a good alternative to an oil or gas heating system, as wood is inexpensive and CO 2 neutral in combustion. The Vitoligno 200-S is a high quality wood gasification boiler with output stages of 20, 30 and 40 kw. It modulates and adapts continuously to the current heat demand. Logs up to 50 cm long are easily handled by the large stainless steel hopper. This means the combustion time can last up to twelve hours without recharging. Heat-up in just three minutes The heat-up process is complete after just three minutes. The extraction of oxygen from inside the hopper means that the logs smoulder, rather than burn. No flame is produced because the wood gas lacks the oxygen necessary for a flame to develop. The combustible wood gas burns cleanly at high temperatures, both under partial and full load. Convenient with automatic ignition To heat up the fuel, an automatic ignition device is available as an optional extra. The control unit also enables the programming of the ignition time. This is especially convenient if you like to return to a warm house after a long journey. Digital control The menu-guided Ecotronic boiler control unit makes the operation of the Vitoligno 200-S particularly easy. Up to three heating circuits can be controlled. Furthermore, the heating water temperature can be conveniently regulated via the integral buffer cylinder management system. Easy cleaning The Vitoligno 200-S heat exchanger is quick and easy to clean using a mechanical lifting mechanism. Due to the high combustion efficiency, the wood burns with few residues. This means that in the heating season the ash only needs to be removed once a fortnight. An ash box with a lid is available for taking the ash to the bin without any mess Vitoligno 200-S Fully wired control unit with user prompts 2 Continuous variable speed induced draught fan for modulating operation mm thick thermal insulation 4 Heating surfaces 5 Large hopper door 6 Convenient heating surface cleaning system 7 Large hopper 8 Combustion chamber made from durable fireclay 9 Automatic ignition (optional) 10 Infinitely variable primary and secondary air apertures

20 Log boiler Pyromat ECO 40 to 170 kw The Pyromat ECO was developed specifically for the combustion of logs and represents state of the art combustion technology. Pyromat ECO log boiler for 1 m logs, 85 to 170 kw Integral heat management The Pyromat ECO was developed specifically for the combustion of logs and represents state of the art combustion technology. The Pyromat ECO log boiler has already stood the test in thousands of applications. Charging from the top makes it easy to use, control via the Lambda probe guarantees low emissions, and the integral heat management ensures maximum convenience. Clean and efficient combustion The microprocessor-controlled Ecotronic captures all details relevant for the operation and regulates the amount of heat required and provided. As a result, the boiler system is monitored continually through all operating phases, from heat-up and operation under load, right through to burnout, and is held within its optimum operating range via its motorised air dampers. This guarantees clean and efficient combustion Applications The Pyromat ECO can regulate up to three heating circuits with a 3-way mixer, a heating water buffer cylinder and a DHW cylinder. It can be used in detached houses, apartment buildings, agricultural applications and commercial operations. Large hopper Thanks to its large charging chute, the Pyromat ECO offers great operating convenience during heating, whether with logs, wood briquettes or wood remnants, either loose or in pieces. Log boilers with a rated heating output range of 40 to 75 kw can be charged with logs of 50 cm length. In the 85 to 170 kw range the hopper width increases to 1080 mm, ensuring convenient charging even with logs of 1 m length. With oil burner connection The Pyromat ECO is also approved as oil boiler compliant with EN standard; the necessary connections are already in place. Adding an oil burner may, for example, help to bridge holiday times when manual charging with logs is not feasible. 1 Pyromat ECO Easily accessible hopper door for charging the log boiler from above 2 Ecotronic control unit 3 Hopper tapering downwards for reliable fuel recharging 4 Degassing zones with cast stainless steel grate and fireclay bed 5 Large, easily accessible ash box for the grate ash 6 Combustion chamber made from high temperature-resistant refractory concrete 7 Ash container below the heat exchanger 8 Flue gas fan with Lambda probe and flue gas temperature sensor 9 Vertical tubular heat exchanger 10 Top cleaning cover 11 Return temperature raising facility as part of the standard delivery (boiler assembly) with boiler circuit pump, boiler control valve, flow and return temperature sensor

22 Wood boiler Pyromat DYN 35 to 100 kw The Pyromat DYN is suitable for manual charging with logs and wood remnant pieces, as well as automatic charging with pellets, chippings, wood briquettes or loose wood remnants. Pyromat DYN 35 to 100 kw The Pyromat DYN can convert many forms of wood fuel into heating energy. An ignition fan system automatically ignites the charge if the wood boiler is equipped with automatic charging. Combined with a DHW cylinder, this permits perfect control in the case of low loads (DHW mode in summer). Self cleaning heat exchanger surfaces The vertical heat exchanger surfaces are continually cleaned by motorised coil springs. The drive mechanism is sited low down inside the protected cool gas flow. The springs can be removed easily for the annual cleaning by the flue gas inspector/chimney sweep. The high efficiency of the Pyromat DYN is the result of a long burnout path, the optimum heat transfer, self-cleaning boiler passes and the utilisation of residual heat in the ash. In standard operation, the ash is automatically removed from the main combustion chamber into the front combustion chamber, where it remains until all incandescence has ceased. Large hopper The large hopper above the combustion chamber allows for convenient operation with logs. A simple push of a button is enough to change over to log combustion (patented air damper function).

Page 34

28 System technology Pellet storage Pellet silo Complete pellet systems Pellet storage with discharge systems for every application area. For lasting and reliable operation, the pellet boiler, discharge system and pellet store must form a matching unit. Pellets can be supplied by means of tankers and blown into the pellet storage room. A hose length of 30 metres should not be exceeded when filling the storage room. If longer hose lengths are to be expected, please consult your pellet supplier for clarification of their technical capabilities. The access route must be suitable for tankers. Generally a road width of at least 3 metres and an overhead clearance of at least 4 metres is required. If possible, the storage room should adjoin an outside wall. There should be a 230 volt power connection for the pellet supplier's vacuum fan and an electrical isolator for the pellet boiler.

29 28/29 Storage with charging of the pellet boiler via vacuum system The vacuum supply system is particularly useful wherever the storage room does not directly adjoin the installation site of the pellet boiler. Pellets can be transported over a distance of up to 15 metres with the vacuum supply system. The flexible positioning of the vacuum system enables installation even in tight spaces. The vacuum supply system can also be adapted to a room discharge screw conveyor or a pellet silo. Storage room with charging of the pellet boiler via vacuum system Pellet silo (fabric container) with charging of the pellet boiler via vacuum system Storage with charging of the pellet boiler via flexible screw conveyor If the storage room or the pellet silo is situated immediately adjacent to the boiler room, the pellet boiler can be charged via a flexible screw conveyor directly to the rotary lock valve. Using this system means there is no need for a pellet hopper at the boiler. The drive unit for the flexible screw conveyor is installed directly at the boiler on the rotary lock valve.

30 Pyromat Storage and supply systems for the Pyromat DYN The adjustable supply screw conveyor is easy to install and can be tailored to the specific physical site conditions. Our pellet discharge systems are patent protected. For chippings Solid room discharge A bottom agitator with two leaf spring arms fills a screw conveyor channel let into the floor. The agitator and screw conveyor are designed for robust operation and high torque. This safeguards a trouble-free and reliable fuel discharge of a wide range of chippings. The stable torque support protects the gearbox against overloads and ensures a consistently smooth and quiet operation. For pellets Very quiet supply screw conveyor with low power consumption The supply screw conveyor is made from hardened steel (chrome-nickel steel) and is characterised by its high torsional strength, resilience and very low friction losses. Outside the store room, the feed pipe is made from natural chrome-nickel steel. Flame proof boiler feed with dispensing hopper The solidly constructed feed screw conveyor made from heat-resistant chrome-nickel steel transports the fuel whether pellets or chippings into the combustion chamber in accurately dispensed volumes. Located above the screw conveyor is a dispensing hopper with light guard that determines the level of the separating fuel layer. This fuel barrier prevents an exchange of gases and consequently fuel burn-back. A second burn back protection device takes the form of the tested shut-off gate. This spring-loaded gate opens during the heating phase and closes automatically afterwards or in the case of a power failure. Fuel silo for chippings with solid room discharge Fuel silo for pellets with quiet and energy saving plastic supply screw conveyor

31 System components for Pyromat ECO and DYN 30/31 The complete system from a single source.

32 System technology Solar thermal systems and photovoltaics Vacuum tube collectors can be installed anywhere, and in new build also make for an attractive architectural feature. Solar thermal systems free solar energy Complement your new wood boiler with the right choice of solar technology. Then you'll save twice as much precious heating energy. Any new heating system simply cries out for the addition of a solar thermal system. There are good reasons for this. In the summer, almost the entire energy demand for DHW heating can be covered by solar collectors. In spring and autumn, this system can also backup your central heating system. In a new build this means you can save up to 35 percent of the total heating energy. Calculated over the year, 60 percent of energy can be saved on DHW heating alone. This is because solar energy is free, and the collector converts daylight into heat even when the sun is not shining directly onto the roof. The principle is quite simple To capture solar rays and then utilise them efficiently sounds more difficult than it is. Of course, a great deal of innovative technology and experience are required. Solar thermal systems "collect" solar energy in the flatplate or tube collectors. In these, a heat transfer medium is heated by insolation and routed into a DHW cylinder. There, the heat is transferred via an indirect coil to the domestic hot water to be heated, or to the heating circuit. Thereafter, the cooled liquid is returned to the collector, and the cycle begins again. If there is insufficient insolation, e.g. in winter, reheating is provided by the boiler.

33 32/33 The Vitosol range offers solar collectors for every aspiration and every budget. Installation on the roof or wall opens up a variety of design options. Flat-plate and tube collectors The Vitosol 200-F flat-plate collector distinguishes itself through its high quality, lasting operational reliability and high efficiency. The high performance Vitosol 300 F flat-plate collector with extremely translucent anti-reflex glass and highly selectively coated copper absorbers utilises intensive solar radiation particularly efficiently. The Vitosol 200-F flat-plate collector features frost and hail-proof safety glass, as well as corrosion-resistant components made from stainless steel and aluminium. The frames are available on request in any RAL colour. Outstanding quality you can rely on: German consumer association "Stiftung Warentest" rated the combi solar thermal systems Vitosol 200-F, Vitocell 340-M and Vitosolic 200 as "Best in Test Good" in its March 2009 edition. More information at With the Vitosol 200-T vacuum tube collector, which employs the heat pipe principle, Viessmann has increased the operational reliability of solar collectors to the extent that they can be installed anywhere. The Vitosol 200-T can be installed vertically and horizontally at any angle between 0 and 90 degrees. It is as suitable for private as for commercial systems. German consumer association "Stiftung Warentest" rated the Vitosol 200-F as "Very Good" in its March 2008 edition. More information at The Vitosol 300-T meets the highest demands.

34 System technology Domestic hot water The Vitocell range from Viessmann offers the right DHW cylinder for every demand, ideally matched to your boiler or solar thermal system. DHW convenience for every demand With our Vitocell DHW cylinders we offer a convenient solution to supplying your household with hot water the perfect extension to your new wood boiler. The demand for hot water is different in every household. One factor is the number of residents and another is their bathing and showering habits. For example, several people in one household often leave for work and school at the same time, so lots of hot water needs to be continuously available for the shower in a short space of time. Those who prefer a bath will also want to have enough hot water to fill the tub. Similarly, a DHW cylinder in an apartment building should be able to deliver a sufficient supply if hot water is drawn from more than one outlet at the same time. Vitocell DHW cylinders fulfil these requirements in every respect and can also meet every aspiration where equipment levels are concerned. In all instances, the installation of a solar thermal system is recommended to save energy and heat the water without cost.

35 34/35 The right DHW cylinder for every demand In the Vitocell cylinder range, you'll find exactly the right DHW cylinder for your requirements. Subject to DHW demand and installation options, select a freestanding DHW cylinder, or a cylinder for installation adjacent to or below the boiler. Hygienic DHW provision The quality of the inner surface of the DHW cylinder is crucial to providing DHW hygienically. For this reason, Viessmann relies on two high quality materials: Ceraprotect enamel coating for safe, lasting protection against corrosion in the Vitocell 100 range, and stainless steel in the Vitocell 300 range for the highest of hygiene standards. The indirect coils inside Vitocell DHW cylinders reach right down to the cylinder floor. This enables them to heat the entire water content, making them very economical. Vitocell 100 with Ceraprotect enamel coating The Vitocell 100, with Ceraprotect enamel coating, meets all requirements for convenient, economical DHW heating and is amongst the top selling enamelled DHW cylinders. The Ceraprotect enamel coating provides the DHW cylinder with secure and lasting protection against corrosion. Vitocell 300 made of stainless steel Vitocell 300 DHW cylinders made from corrosion-resistant stainless steel meet some of the most stringent hygiene standards. Stainless steel is used in kitchens, laboratories, hospitals and the food processing industry for good reason, as it offers excellent hygienic properties. Its homogeneous stainless steel surface retains its hygienic properties even after many years of use. Take advantage of these benefits: Vitocell with Ceraprotect enamel coating or made from stainless steel Capacity: 80 to 1000 litres Dual mode and multi mode DHW cylinders for the integration of solar thermal systems for DHW heating and central heating backup Internal indirect coils reaching right down to the cylinder floor heat up the entire water content Low heat losses through highly effective thermal insulation 1 2 Vitocell 300-V 3 1 Vitocell 300-V made from stainless steel.
