Solo Plus, a patented, wood-fired gasification boiler. Three sizes available with outputs from 100,000-198,00 BTU/hr.

HS –TARM Solo Plus boilers provide a convenient, safe and environmentally friendly way to heat your home and domestic hot water with wood. Solo Plus boilers assure the independence and self-reliance that heating with wood provides. Because they use the “magic” of wood gasification combustion, they give unusually high overall heating efficiency. They use substantially less wood than conventional boilers and outdoor water stoves.

Solo Plus boilers burn so clean, they are safer (virtually no risk of a chimney fire) and result in cleaner air for everyone. They also help to substantially reduce greenhouse gas emissions. HS-TARM Solo Plus boilers enable you to increase the warm security of your home in a safe, environmentally responsible way. Everyone wins!
For more than 70 years, HS-TARM has been a pioneer in the development and production of residential central heating equipment. HS-TARM's primary objective is quality, function and appearance... excellence on all levels. In fact, HS-TARM has earned the prestigious ISO 9001 certification, which assures consistently reliable product quality.
Operational reliability, unique firing efficiency, total quality, and concern for the environment, are all factors that have been instrumental in HS-TARM becoming an internationally recognized supplier of central heating boilers.

Combustion is regulated by a thermostatically controlled draft blower that forces combustion air into the boiler’s ceramic combustion tunnel. Here, unusually effective combustion takes place at very high temperatures allowing the Solo Plus to use very little fuel in comparison to “conventional” boilers.

HOW THE SOLO PLUS-MKII WORKS

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.
