Overview
Big-stove heat in a slim European frame — and the lowest price in the ComfortBilt lineup.
The HP50S has been a fixture in European homes for years, and its compact footprint is exactly why: it slips into spaces where boxier stoves won't, while still pushing over 35,000 BTU and heating up to 2,400 sq ft with 80.4% EPA-certified efficiency. The 47 lb hopper keeps burn sessions long, and the adjustable glass air-wash damper keeps the flame view clean between weekly cleanings.
You get the same control stack as ComfortBilt's flagship stoves — five heat levels, Temp mode with ECO auto-cycling, 7-day scheduling, wired-thermostat support, and an included remote. Four finishes, including Arctic White — a rarity in pellet stoves — plus Black, Burgundy, and Dark Brown.
For condos, cabins, smaller homes, or anyone who wants pellet heat without a big-box silhouette, the HP50S is the sweet spot of price, size, and output.
