Pellet Inserts for Masonry Fireplaces

Why Families Choose Pellet Inserts

A pellet insert turns an open masonry fireplace into a clean, consistent heater you run from a thermostat. The unit sits inside your firebox, a hopper holds the pellets, and the stove feeds itself—so the fireplace that used to pull warm air up the chimney becomes the room’s best heat source. Pellets burn clean and consistent, and they are affordable, available, and renewable.

Harman and Quadra-Fire inserts are sized to the opening you have, with a surround that finishes the gap, so measure your firebox or bring photos to the showroom and we’ll match you to the models that fit. Most of the heat is convectional—blown through a heat exchanger and out into the home. Automatic thermostats and temperature controls do the work for you—just keep your hopper filled.

Every pellet insert vents up the existing chimney through a new liner and needs an outlet nearby. Pellets are normally available in 40 lb. bags. A 1,500 sq. ft. home will use 2-4 tons per season, on average. Our trained in-house team handles the liner, the power, and a safe, code-compliant installation, and we service what we sell—including the annual cleaning a pellet insert needs. Price any insert below, then see one running in the showroom.

We purchased a propane fireplace from Hearths A'Fire and had little to no experience with installation or maintenance. The customer service here is exceptional. I cant say enough about a gentleman by the name of Brian. He has gone far above and beyond for me in any time of need. He's about as professional and personable as anyone I've encountered and has truly shown he cares. He recently came with another very helpful gentleman by the name of Luke, even when their schedules are packed, to help me resolve a maintenance issue. Im truly thankful for the customer service I've received from these folks. Highly recommended!

More questions & answers

How much does a pellet insert cost installed?

Less than a built-in pellet fireplace, because the opening and the chimney already exist—the variables are the unit, the liner, and the surround. Every insert on this page carries a price tier, and the instant estimate narrows it to your fireplace. Your in-home evaluation makes it exact.

Will a pellet insert fit my fireplace?

Most masonry fireplaces take one. Measure the opening—height, width, and depth—or bring photos to the showroom. The in-home evaluation confirms the fit and the chimney before anything is ordered.

Does it need electricity?

Yes—the auger and the fans run on power, so there’s an outlet to plan for. If outages matter to you, ask us about backup options before you pick a model.

How often does it need cleaning?

Empty the ash pan every week or two in heavy use, and give it a thorough cleaning once a year—we schedule annual cleanings April through August.

Who installs it, and what about service afterward?

We install what we sell—our trained in-house team handles a safe, code-compliant installation with attention to detail—and we service what we sell, so we’ll be here long after installation to make sure everything works the way it should.
