HVS Boilers are available for burning natural, split logs with log lengths of 33, 50, 70 to 100 cm (depending on the size of the boiler), optionally with or without lambda control with a nominal heat output of 16, 25, 40, 60 and 100 kW.
With the log boilers from Solarbayer heat in an environmentally friendly, CO2-neutral and ecological way with maximum energy efficiency and an excellent price / performance ratio.
* Please note the BAFA funding criteria.
Fill in wood, light and everything else runs automatically. The large filling space of the wood gasification boiler ensures a long burning time. The integrated fan guarantees a problem-free start even when the fireplace is cold. The fire flap and door lock prevent smoke from escaping. In addition, the fan stabilizes the combustion over the entire burning time and enables absolutely problem-free operation. Even our "smallest", the HVS 16 LC, is already excellently suited for heating a single-family home with a low-energy standard. From a boiler size of 25 kW, the large filling door can be used to comfortably heat with half-meter logs, whereby a certain excess length of the logs does not cause any problems due to the depth of the filling chamber. For larger buildings, the wood gasification boilers HVS 60 with 70 cm log length or HVS 100 with meter logs can be filled. The large filling volume results in long refilling intervals. The inside of the filling chamber is provided with a "hot air duct", which increases performance and achieves the best exhaust gas values.

In the wood gasification boilers of the HVS LC series, a modern and modular control concept with monitoring of the exhaust gas values through the standard built-in lambda probe ensures more output and, at the same time, low, environmentally friendly pollutant emissions. Based on the integrated boiler and flue gas logic, the intelligent control recognizes the power requirement. By means of the modulating air supply, the wood gasification HVS LC can react to excess power and ensure optimal and almost perfect fuel utilization. This offers you the best possible comfort and constant, even combustion for your wood. Optimal system efficiency can only be achieved with a perfect team. We therefore generally recommend our high-performance stratified storage SPS type SPS with a patented built-in stratification system for wood heating systems. The heat produced by the wood boiler can be optimally stored here. The heater then calls up the stored heat as required. This also protects the environment and keeps your fuel consumption as low as possible.
The wood gasification HVS Economic achieves extremely clean emission values even without lambda control. By using the latest control technology, a product has been created that falls below the strict emissions standards that have already been set. With this boiler series you make the best possible use of the fuel and thus protect our environment. Each of these models is equipped with the electronic combustion control as standard. The permanent monitoring of the flue gas and boiler temperature means optimal comfort for you and constant, even combustion for your wood. The physics of the combustion process was copied from nature and integrated into our wood gasification boiler in an excellent way. The logical interplay of flue gas and boiler temperature rise in certain time sequences is used here to optimize the supply of combustion air.

To 01. January 2020, BAFA significantly increased the subsidies for heating with renewable energies (solar thermal, biomass and heat pumps). The grants are no longer granted as a fixed amount subsidy, but as a share financing (percentage subsidy) on the basis of the eligible investment costs, so that the acquisition costs, assembly costs and many other costs can be recognized from now on. Further details on the eligible costs are available on request.
