Arikazan wood gasification models range from 20 kW up to 100 kW, with efficiencies above 90%, and automatically move between loading and combustion mode. There are also two self-lighting log and pellet combination boilers. Great build quality, advanced features, good value.
Vigas make log gasifying boilers with outputs from 25-80kW and efficiencies in excess of 80%. The Vigas uses one fan to supply combustion air to burn the wood gases and to regulate the output of the boiler.
