ComfortBilt Pellet Stoves & Inserts

Bundles, inserts, and accessories

Several ComfortBilt stoves are also sold as money-saving bundles that pair the stove with a matching hearth pad — the HP22, HP22N, HP50S, HP61, and HP21 combos ship the floor protection with the stove. If you're fitting an existing masonry fireplace rather than standing a stove on the floor, the HP22i insert drops into the opening. For a model-by-model breakdown, read our guide to every ComfortBilt model, or compare the wider range in our full pellet stove lineup.

What you'll need for installation

ComfortBilt stoves vent with sealed 3" pellet vent pipe, which can run horizontally straight out through an exterior wall — no full chimney required, which is what makes them practical in a home without an existing flue. You'll also need a hearth pad rated for your model and the clearances printed in the owner's manual; see our clearance guide. Each product page lists that model's clearance requirements and the venting parts it needs.

How ComfortBilt compares to other pellet brands

Most pellet stove shoppers are choosing between a value brand and a premium one. Our Quadra-Fire vs ComfortBilt comparison sets the two side by side on heat output, hopper capacity, and what the price gap actually delivers. The Lopi vs Drolet and ComfortBilt guide widens that out to cover wood stoves as well, which is useful if you haven't settled on a fuel yet.

ComfortBilt pellet stove FAQs

What makes ComfortBilt pellet stoves different?

ComfortBilt builds a wide range of hopper sizes and cabinet styles around a similar thermostat-controlled auger system, so you can match heat output and refill frequency to your home without switching brands. The HP22 is one of the best-selling pellet stoves in the country, and the line runs from the compact HP21 up to the 3,000 sq ft HP75C.

How long does a hopper of pellets last?

It depends on hopper size and how hard the stove is running. Hopper capacities range from 40 lb on the HP21 to 80 lb on the HP22N, which the manufacturer rates for up to 32 hours between refills on a low setting. Expect shorter intervals on a cold night at high output. Each product page lists that model's hopper capacity.

Do ComfortBilt stoves need a chimney?

No. ComfortBilt pellet stoves use sealed 3" pellet vent pipe and are commonly vented straight out through an exterior wall, so they don't need an existing masonry chimney. See our pellet venting parts for the pipe and fittings.

Do ComfortBilt pellet stoves need electricity?

Yes. Like all pellet stoves, they run an electric auger, igniter, and blower, so they need a standard 115V outlet. If you want heat during an outage, plan for a battery backup or generator with a pure sine wave output, which the control board requires.

Is StoveSource an authorized ComfortBilt dealer?

Yes. We're an authorized ComfortBilt dealer, so every stove carries the full manufacturer warranty and factory support. ComfortBilt's warranty covers the stove for one year, with longer coverage on select components as listed in the owner's manual.

Do you charge sales tax on ComfortBilt stoves?

No. StoveSource charges no sales tax in any state, and orders over $250 ship free to the lower 48.

Choosing between them

We're an authorized ComfortBilt dealer, so your warranty is fully supported. Most ComfortBilt stoves currently include a free accessory with purchase — the included gift is shown on each product page.

Choosing between them

A larger hopper doesn't add heat — it just means fewer trips with the pellet bag. Burn times below are the manufacturer's figures on the lowest of five power settings; expect shorter intervals at high output on a cold night. Between sizes?
