Basically, the new laws apply only to freestanding and built-in “space heaters” which burn wood in a controlled manner (so-called “air tight” stoves). The standards call for these appliances to be able to burn very cleanly, up to 10 times cleaner than older stoves. They also must burn cleanly at all settings, from very low to very high. Certain Solid Fuel appliances are exempt from these standards. Coal stoves, open fireplaces, cook stoves and all central heating units are not required to meet these standards.

If you already have a wood stove, don't worry! All existing stoves and “grandfathered” and allowed to be used. The law only applies to manufacturers and retailers. Still, it is smart to upgrade your system to a more efficient model whenever possible. This will help us all clean the air and make better use of our resources.

HS-TARM Excel and Solo Plus boilers would easily meet or exceed these standards. In fact, the country of Sweden (where HS-TARM is a big seller), has strict standards on the pollution and efficiency of boilers. Although our MB-Solo series is not as clean as the Excel and Solo Plus boilers, MB-Solos are still the best available of their type. Much time and effort is invested in the design and engineering of all our Central Heating Systems so you can get the most heat – from the least amount of wood.

The Chart below shows the amount of smoke and pollution (figures in grams of smoke) released into the air to produce an output of 100,000 BTU, enough to heat a large home for 1 or 2 hours. A gram of smoke is roughly the amount produced by a cigarette. Compare for yourself how an HS-Tarm boiler is the cleanest solution.
