Overview
The HP75C is ComfortBilt's flagship — the most powerful, most efficient pellet stove they make.
Up to 43,298 BTU and 3,000 sq ft of coverage put the HP75C at the top of the range, and its 80.7% EPA-certified efficiency is the best of any ComfortBilt stove. The oversized 65 lb hopper delivers up to 22 hours of continuous burn, the vermiculite-lined firebox frames a wide ceramic-glass flame view, and four designer finishes — Satin Black, Cream, Green, and Brown — make it the rare pellet stove chosen for looks as much as heat.
Same trusted control stack: five heat levels, Temp mode with ECO, 7-day scheduling, wired thermostat support, and an included remote.
For large homes, design-forward spaces, or anyone who wants ComfortBilt's best, this is it.
