Overview
Turn a drafty fireplace into a 40,000 BTU heat source — the HP22i is the HP22's engine in insert form.
The HP22i slides into an existing masonry or approved factory-built fireplace and replaces open-hearth heat loss with 80.5% EPA-certified efficiency and up to 2,800 sq ft of coverage. At 1.01 g/hr it's the cleanest-burning stove ComfortBilt makes. The 47 lb hopper feeds long burns, and the included 43" × 32" surround panel finishes the opening cleanly, with the room sensor routed discreetly through the shroud.
You keep the full ComfortBilt control stack — five heat levels, Temp mode with ECO, weekly scheduling, thermostat support, remote included — and the maintenance-friendly design carries over: heat-tube scraper, removable ash pan, glass air-wash damper.
Pair it with the 3" flexible liner kit so the insert stays serviceable for annual cleanings — with rigid piping, the unit can't be pulled out for maintenance.
