A wood burning fireplace insert turns your existing fireplace into a real wood heater instead of letting heat go to waste. These seven Osburn inserts range from a compact unit with tapered sides and top to the largest in the line. You may also know one as a wood stove insert or wood fireplace insert. Burn dry, seasoned firewood and turn the air control down for longer burns.


How to choose a wood burning fireplace insert

The Osburn insert line starts at 250 to 1,200 square feet for a bedroom or den and reaches 1,000 to 2,700 for a large home. Mid-size choices suit an open living area. They burn 7 to 10 hours on one load, longest in the largest insert. Firebricks line the firebox and hold heat, and glass doors show the flames. One has a cast iron door. A blower pushes warm air into the room; several include it, while others offer it optionally. All are non catalytic and meet current EPA clean air rules.

Fitting the opening and chimney

These fit only a masonry fireplace, brick or stone, never factory built. Measure width, height and depth, front and back. A surround covers the gap. Your chimney usually needs a steel chimney liner; liner hookup parts are on each product page.

Other ways to go

Without a suitable fireplace, consider a freestanding wood stove on a hearth pad. For switch-lit heat without logs, see gas inserts. Choose plug-in electric inserts if you want no chimney work.

FAQ

Can you put a wood burning insert in an existing fireplace?

Yes, if it is masonry, brick or stone, and never factory built metal. The insert slides in, a surround covers gaps, and a steel liner runs down the chimney to it. Measure width, height and depth, front and back, to check the fit.

Do I need a chimney liner?

Almost always, yes. A steel liner gives smoke a tight, right-sized path through the old chimney. An installer or chimney sweep fits it. Find hookup parts on each product page and liners on our chimney liner page. Ask us to quote the run.

How much space can a wood burning fireplace insert heat?

Osburn rates the compact insert for 250 to 1,200 square feet, smaller and mid-size choices for 500 to 1,800 or 500 to 2,100, the large for 750 to 2,200, and the largest for 1,000 to 2,700. Choose a range with your space near its middle. Open layouts heat more easily than closed rooms.

Should I get a wood insert or a freestanding wood stove?

A wood burning fireplace insert uses your brick or stone fireplace. A freestanding stove stands on a hearth pad where you can run a chimney. Both keep burning during power outages; only the blower stops. Choose the size your room needs, not the biggest.
