2 Ecological hea ng with highest comfort! Li le e ort from refueling to cleaning! Just ll in logs, ignite them and everything else is working jsut by itself. The large fuel chamber provides a long combus on period. The integrated fan guarantees an unproble ma c start. The fuel chamber door and its bolt do not give way for smoke emission. Mo reover, the combus on is stabilized throughout the whole combus on period by the fan and enables an unproblema c opera on. Even the boiler size with 25kW can comfortably be lled with 0,5m logs through the large fuel chamber door. An overlength of the logs is, at least to some extent, no problem due to the depth of the fuel chamber. Long refueling intervals are the result of the large lling capacity. An increase in performance and very good exhaust gas values are achieved by an hot air duct inside the tank kw output Two di erent types are available: Op on I HVS E [without lambda control] Op on II HVS LC [with lambda control] Advantages of the SOLARBAYER wood log boiler: Gasifying wood log boiler with downward combus on and upward wood gasi ca on solid boiler construc on and robot manufacturing guarantee a long service life solid contruc on of the fuel chamber All re swept parts are made of special 6mm boiler steel new designed fuel chamber geometry Consistent and cer ed boiler technology with innova onal developments exhaust gas turbulators for more performance and lower exhaust gas temperatures easy handling and cleaning up to 30% more e ec ve combus ble u liza on than with standard wood log boilers modula on combus on, exhaust gas control as well as an op onal lambda control (op on HVS Lambda Control) take care of the observa on of the momentary valid limit value of the German BIMSch regula on 2 Wood log hea ng HVS

Due to the use of latest control technology a product was created that under runs the already determined exhaust gas requirements. You can make the best possible use of the combus ble with this boiler series and you also respect the environment. Each model is equipped with the electronic combus on control. The permanent observa on of the exhaust gas and boiler temperature means perfect comfort for you and a steady and even combus on for your logs. The physics of the combus on process has been adopted from nature and integrated into our boilers in an excellent way. The logical coopera on of exhaust gas and boiler temperature in certain intervals is used to add the combus on air in an op mized way. Op on I: HVS E [without lambda control] Available in boiler sizes 25, 40, 50 and 80 kw nominal heat output HVS LC LAMBDA CONTROL Combus on op mized performance and ring control unit due to permanent lambda control The outstanding concept of the HVS boiler which has been further developed by permanent innova ons has now reached the next genera on. The permanently increasing environmental impact by dust and CO 2 urges the industry on new developments and more modern technology in all areas. A modern and modular control concept of our wood log boiler series HVS LC ensures more performance and a low, environmentally friendly pollutant emission due to the serially integrated lambda sensor which observes permanently the exhaust gas values. With the help of the integrated boiler and exhaust gas logic the intelligent control recognizes the requirements of energy. Due to the modula ng air supply the boiler is able to react to a possible power reserve and can therefore ensure an almost perfect exploita on of combus bles. This means the highest possible comfort for you and a steady and even combus on for your wood. You can only achieve an op mal e ciency factor with a perfectly aligned system. Therefore, we generally recommend our high quality stra ca on tanks SPS with integrated, patented, stra ca on system. The produced heat of the wood log boiler can be perfectly stored in this kind of tank. The stored thermal energy is relieved into the hea ng system when needed. This keeps your fuel consump on as low as possible and even preserves the environment. lambda sensor actuator exhaust gas sensor Permanent combus on op miza on due to exhaust gas analysis via lambda sensor and adjustable exhaust gas temperature forced draught fan The actuator guarantees a perfect adjustment of the air quan ty Op on II: HVS LC [with lambda control] Available in boiler sizes 16, 25 and 40 kw nominal heat output Wood log hea ng HVS 3

6 Ecological hea ng with highest comfort! The interac on of all components is decisive for the e ciency factor of a wood log boiler system. Solarbayer wood log boiler sets always include stra ca on bu er tanks SPS. This guarantees a fast and e cient heat conduct into your building. Due to the enormous hea ng performance of our boilers the installa on of a bu er tank is inevitable. A bu er tank volume of 55 liter per kw nominal boiler output has to be installed. In order to achieve a perfect e ciency factor we recommend to install a bu er tank volume of 70 to 100 liter per kw nominal boiler output, depending on the space condi ons in your boiler room. The best possible tank for this is our stra ca on bu er tank SPS with integrated stra ca on system SLS. The characteris c aspects of these systems are the long refueling intervals as well as the high e ciency factor. With this you will achieve perfect system e ciency. Opera ng mode of our stra ca on bu er tanks with stra ca on system SLS Perfectly aligned sets Our wood log boiler sets consist of the following components: Solarbayer gasifying wood log boiler two di erent types are available: HVS Economic [without lambda control] HVS Lambda Control [with lambda control] Laddomat (boiler charging unit with boiler circuit pump and shut o device, 28 mm compression ng) thermal discharge safety valve (¾ internal thread) with sensor and immersion sleeve patented stra ca on bu er tank SPS with integrated stra ca on system SLS (one of the most e cient systems on the market) membrane expansion vessel suitable for the par cular bu er tank size cap valve for expansion vessel with shut o device, connec on and draining boiler safety unit with bleeder, manometer and safety valve detailed instruc on manual with technical descrip on and installa on instruc on Thermo graphic real me recording of the bu er tank charging process stra ca on system SLS (at top and bo om of the tank) charging removal Real me simula on with Solid Works Flow Simula on The charging of the Solarbayer stra ca on tank is lead into the stra ca on pot via the charging pipe. The thermal extrac on starts as soon as heat is needed, through the discharge pipe into the hea ng system. The heat needed is only taken out of the stra ca on pot and is therefore immediately ready for extrac on. The surplus of energy provided by the heat transfer medium is going to be stored in the bu er tank, perfectly layered, via the boreholes in the stra ca on system SLS (as show in the pictures on the right). The displayed me lapse clearly demonstrates the steady alloca on and stra ca on of thermal energy while the boiler is charged 6 Wood log hea ng HVS

8 Calcula ng the boiler size To determine the exact standard building heat requirement a calcula on in accordance with DIN 4701 for hea ng systems must be made. In order to make a quota on for a wood log boiler hea ng system a rough calcula on is adequate. Decisive in choosing a log burner is the ques on how o en a re ll of fuel is required to meet the daily heat requirements. Please note that with solid fuel boilers the speci ed output is guaranteed under the full load only. A er the pre hea ng phase it will take about 30 minutes un l the boiler will operate with its maximum output which will last for approximately 2 hours. Now the burn o period begins. During this period (approx. 1,5 hrs) the boiler already operates with decreased power. The rebed remaining in the combus on chamber will post heat for about an hour. A erwards the combus ble is completely used up. Thus, the boiler can generate the nominal output speci ed for approx. 4 hours. By mul plying the nominal boiler output with the burning period will show the burning down heat output of the boiler. example (with wood log boiler SOLARBAYER 25 E): burning down heat output = 25 kw x 4 h = 100 kwh For the calcula on of the boiler size by means of living space the speci c heat requirement of the building at an outdoor temperature of 16 C is needed. Old building 0,12 Kilowa / m² New building (from 1995) 0,08 Kilowa / m² Low energy house in acc. with EnEV ,05 Kilowa / m² The hourly heat requirement is calculated by mul plying the speci c heat requirement and the living space of the building. Example of a new building from 1997 with 150 m² living space: heat requirment = 150 m² x 0,08 kw/m² = 12 kw By means of the daily heat requirement and the corresponding burning down heat output of the boiler it can be determined how o en the boiler chosen must be lled with fuel: Our example of the wood log boiler Solarbayer 25 E in a new building with a living space of 150 m² shows how to calculate the number of fuel re lls per day to meet the heat requirements of the building. Thereto, we need to add the daily hot water requirement of approx kw per person per day. (12 kw x 24 h) : 100 kwh = 2,88 = approx. 3 boiler llings Your installer will be pleased to assist you: Solarbayer GmbH (2310) Technical changes and errors reserved
