Our take on the HP21 Pellet Stove

The ComfortBilt HP21 is a freestanding pellet stove with a bay-view window and pedestal base. It delivers up to 32,000 BTU per hour and is rated to heat up to 2,400 square feet in mild conditions. A 40-pound hopper runs up to 16 hours on the lowest setting, and a programmable thermostat and remote add convenience. It competes with other mid-size pellet stoves on capacity and features, though its efficiency (76.3% HHV) is about average.
