The Harvia GreenFlame 22 is a timeless and elegant black wood-burning stove that features a large glass door to create a unique atmosphere that highlights the fire beautifully. The GreenFlame 22 stove is best suited for medium-sized saunas up to 635 cu. ft. and boasts 70% lower emission levels thanks to the GreenFlame technology.

Requires a minimum of 88 lbs of stones, sold separately.

The stove is perfect for medium-sized saunas and boasts lower emission levels thanks to the GreenFlame technology. GreenFlame ® ensures a controlled burn, reliable operation and a long life for your stove. The stones of the WKLI22GM stove heat the entire sauna quickly, offering enough heat even for the most demanding sauna bathers. Linear GreenFlame represents pioneering quality in sauna heater technology.

The heart of the heater is a fully updated GreenFlame ® fire chamber, which has been designed with clean combustion in mind. The new fire chamber reduces the particulate emissions generated by wood combustion by 20% and carbon monoxide emissions by 70%. The updated GreenFlame fire chamber is an element in Harvia’s determined development efforts towards cleaner combustion and emission reductions. As a long-term goal, Harvia has decided to cut the particulate emissions of wood-burning stoves by half.
