The Walltherm® provides wood gasification efficiency and shows beautiful flames in two combustion chambers. With the Walltherm® you can heat your whole house, including the domestic hot water. Especially in winter the stove creates a very pleasant and comfortable atmosphere with the double flames .

The award winning Walltherm Zebru, is the most efficient wood burning stove in the world. The stove is available in black or grey and has a nominal output of 10.5 kW to water and 4.5 kW to the room. The combustion rate is thermostatically controlled and the air can be brought directly from outside making it suitable for highly insulated houses. The direct air fitting can be taken from the back or the base of the appliance. The stove would normally be connected directly to a thermal store, allowing you to harness the heat when and where you want it and providing the domestic hot water as well as heating the house. There is an option of a log box and tool store, priced separately

This is how the stove works:

The Walltherm has two combustion chambers, in the upper chamber there is the wood which produces wood gas while burning. This wood gas is drawn down into the lower chamber. On the way it runs through the hot glow where it ignites while secondary air is injected. This process creates a very hot flame and burns nearly all residues.

Even if this sounds complicated, no electronic part is involved and neither does it use a drought generator. Because of a very clever heat exchanger the flame is drawn down only but the natural drain provided by the chimney.
The resulting efficiency is stunning, the wood gasification flame reaches temperatures of up to 1000°C and nevertheless the exiting fume temperature is only about 120-150°C. The temperature difference is used to heat the water in the heat exchanger.
