love it!!!

Tyler Wood
Reviewed ComfortBilt HP21 Pellet Stove

This Pellet Stove has been great in being the only heat source for our home. The only complaint would be the gaskets on the sides of the stove. When performing the monthly cleaning, the gaskets seemed to be extremely fragile and gave us an uneasy feeling when placing the covers back on. The exhaust fan gasket was also extremely fragile.

It puts out a ton of heat. It'll run the entire night with no problems as long as I cleaned it before turning it on.
