This guide compares all seven current models, from the entry-level HP21 to the top-of-the-line HP75C and the HP22i fireplace insert, so you can match the right stove to your home.
Heating-area figures are manufacturer ratings; real coverage depends on climate, insulation and layout. Confirm floor-protection and venting requirements against the owner's manual on each product page before ordering.

All figures above are EPA-certified test values from each stove's product page. Note that ComfortBilt publishes EPA-certified HHV efficiency, which is measured differently from the "optimum" efficiency figures some other brands advertise — our guide to reading pellet stove efficiency ratings explains why those numbers aren't directly comparable.
1. ComfortBilt HP22 — Best Overall
The HP22 is the stove that made ComfortBilt's reputation and remains the default recommendation: 42,000 BTU, up to 2,800 sq ft of coverage, a 55 lb hopper, and 80.5% EPA-certified efficiency. It's available in multiple finishes, and the HP22 + Hearth Pad Combo bundles the floor protection most installs need while saving $249 versus buying separately — one of this month's pellet stove deals. For a deeper look at how it stacks up against its bigger siblings, see our HP22 vs HP61 vs HP75C comparison.
2. ComfortBilt HP75C — Top of the Line
The flagship: up to 43,298 BTU, 3,000 sq ft coverage, a 65 lb hopper, and 80.7% efficiency — the highest in the ComfortBilt range. If you want the most stove ComfortBilt makes, this is it.
3. ComfortBilt HP61
Nearly 40,000 BTU with the largest coverage in the classic line at 3,000 sq ft, fed by a 51 lb hopper. The value route to whole-house pellet heat — and the HP61 + Hearth Pad Combo saves $249 on the install.
4. ComfortBilt HP22N — Longest Runtime
The HP22's output — 42,000 BTU at 80.5% efficiency, up to 2,800 sq ft — paired with a huge 80 lb hopper good for up to 32 hours of continuous burn. If you don't want to refill daily during a cold snap, the HP22N is the answer within the ComfortBilt line. Also available as a combo with hearth pad.
5. ComfortBilt HP50S — Best for Small Spaces
A slim, European-style cabinet that packs 35,000+ BTU and heats up to 2,400 sq ft at 80.4% efficiency. The stove to pick when floor space or aesthetics rule out the boxier classic models. The HP50S + Hearth Pad Combo saves $249. If a compact stove is what you're after, our small pellet stove guide compares it against the HP21 on turndown range.
6. ComfortBilt HP21 — Best Budget Pick
The entry point to the lineup: 31,753 BTU peak output, 2,400 sq ft coverage, a 40 lb hopper, and 76.3% EPA-certified efficiency. It also has the widest turndown in the range, idling down to 12,349 BTU/hr — which makes it the most comfortable choice for genuinely small rooms. The HP21 combo adds floor protection for $99 less than buying separately.
7. ComfortBilt HP22i — For Existing Fireplaces
The only insert in the range: up to 40,689 BTU and 2,800 sq ft from inside your existing fireplace, with the cleanest burn in the line at 1.01 g/hr. It requires the HP22i flexible liner kit, which keeps the insert removable for maintenance.
Which ComfortBilt Should You Buy?
For most homes, start with the HP22. Go HP22N if you want to refill every day or two instead of daily, HP61 or HP75C for 3,000 sq ft coverage, HP50S for tight spaces, HP21 on a budget, and the HP22i if you're converting a fireplace. Every stove ships free with No Sales Tax, and every product page includes the owner's manual with exact clearance and venting requirements.
Cross-shopping other brands?
We also carry the Canadian-built Drolet ECO pellet stoves, which run lower emissions (0.77 and 0.96 g/h) and much larger hoppers — up to 105 hours per fill on the ECO-65R — at higher price points. The USA-made Englander 25-CBPAH is another long-burn option with a 120 lb hopper. Our best pellet stoves roundup ranks everything we stock side by side.
