Wood gasification technique and obtaining wood gas (so-called. Holzgas) is known for long time. Light forgotten again gaining popularity due to ecology reasons and focus on renewable energy sources supported by the European Union. Wood gasifying boilers are the most efficient form of burning large pieces of wood, giving almost twice as much heat than traditionally fired boilers and stoves and are ideal for those who have access to cheap wood like foresters and sawmill owners, timber yards, carpenters and so on. Wood gasification boiler works at his best when the wood is dry, seasoned wood, the lower the humidity the better, more efficient and cleaner combustion.

Similarly, it is possible to burn hard coal, ecologically, efficiently and cleanly.

For wood gasification boilers up to 80 kW, a gasification boiler should work with the device known as Laddomat (automatic pump steering device to correct return water temperature and managing the heat economy of the boiler) and a water accumulation storage tank for maximum profit of the generated heat. Moreover, Laddomat automated hydraulic protects the boiler from overheating in case of stopping the pump (eg. the lack of electricity) by removal of heat from the boiler to the accumulation tank using the built-circulation system. The return water is heated up to prevent condensation and corrosion processes, which prolongs the life of the boiler (in many cases, you can count on an extended manufacturer's warranty for boilers using Laddomat and accumulation tank).

Pellet boilers in the SLIM category are boilers which, due to their design, can be installed in rooms with limited space. Due to the space in the boiler room, the boiler can not always be installed with the conventional solution. Therefore, there are boilers with the tank above the boiler to take advantage of the limited space available.

Boilers, commonly called furnaces are devices used for heating homes, shops, offices, halls, factories and other commercial premises. Furnace or boiler with a feeder and a fan controlled by the controller are currently the highest evolutionary form when refferd to manual hand fired boilers. Automatic boilers have not only a much higher level of efficiency when it comes to combustion and performance but are also characterized by a lower solid fuel consumption and offer a better combustion accuracy and output power management. Digital boiler controllers with user applications allows continuous adjustment control, temperature setpoint and modulated boiler power output and high user comfort. The external fuel storage tank (also called solid fuel silo) allows for unattended operation of the boiler reducing the role of the stoker person who uses the furnance or boiler for storage tank refill, periodic cleaning,conservation and ash carrying outt. If comfortable and ecological combustion is a priority the boiler with feeder is the right choice. For these reasons a boiler with a feeder (auger) for fine coal, pellet or biomass is the most ecological and efficient form of solid fuel combustion.

Specialized wood chips and wood waste boilers of wood and plant origin. The combustion of renewable fuels in the form of wood chips has low emissions and is eco-friendly. Boilers for wood chips are ideal for users with cheap and permanent access to wood waste and wood chips like carpenters, sawmills, lumber yards etc. Wood chips and pellets are playing an increasingly important source of environmentally friendly, renewable energy.
