HearthStone Green Mountain 60 TruHybrid Wood Stove

The Green Mountain 60 is a soapstone-lined TruHybrid wood stove, and the first thing people notice is the fire. Its clean, traditional lines frame a wide view into the firebox.

Behind the glass, soapstone blocks line the firebox. HearthStone says they store heat from the fire and give it back as gentle radiant warmth. The TruHybrid catalytic system carries a 79% efficiency rating (HHV) and certified emissions of 0.6 g/hr. The 2.0 cubic foot firebox takes logs up to 18 inches, and an optional blower kit is available.

Ownership & Maintenance

The TruHybrid system uses a catalytic combustor. Like any catalytic stove, the combustor should be checked periodically and will eventually need replacing. HeatLife is HearthStone's own burn-time rating, so treat it as a guide rather than a promise. Buy from us and you get ongoing service for our customers.
