The combustion system employed in Solo Plus boilers solves most of the problems associated with conventional wood boilers and outdoor water stoves.
Here’s why: The wood gasification combustion process in the Solo Plus boiler begins when the small, quiet draft fan turns on in response to the boiler’s heat controls. The draft fan blows fresh air into the top of the firebox and down through the wood and live charcoal bed. This hot air and smoke mixture is forced through a slot in the top of the ceramic combustion chamber. Super-heated secondary air is then injected into these gases. The combination of the wood gas and smoke with the high temperature oxygen results in a super-hot 1800° flame in the ceramic combustion tunnel. This is the “Wow, that’s unbelievable” process we call wood gasification. The gases stay in this hot, turbulent environment long enough to achieve extremely high combustion efficiency. The resultant heat passes into the vertical heat exchange tubes giving off heat to the boiler water for house heating and domestic hot water demands. The combination of optimum combustion and maximum heat exchange efficiency is what yields the unusually high overall boiler heating efficiencies of 80-85%.

Feel good about heating with wood without becoming a slave to a heater that needs a mountain of wood to keep you warm.
