An Empire fireplace insert turns the wood fireplace you already have into a gas fire with no demolition. You choose the size, venting and look that suit your hearth. Empire Comfort Systems fireplace inserts carry the White Mountain Hearth name, from a family-owned company in Belleville, Illinois, since 1932. Measure the opening’s width, height and depth at the back before you choose a size.

What an Empire fireplace insert does

Each insert slides into your existing fireplace, whether masonry or factory built, with no demolition. A surround covers the old opening, and you can choose natural gas or propane. Compare our gas inserts across brands or visit the Fireplace Inserts hub for wood and electric options too.

Three direct vent inserts and two vent free inserts

A direct vent gas insert uses sealed pipe through your existing chimney to bring in air for the fire and carry exhaust outside. Each direct vent insert offers a standing pilot or electronic ignition and a remote control as an add-on. Innsbrook offers a traditional log fire in direct vent and vent free versions. Rushmore TruFlame has tall flames that wrap the logs. Rainier pairs a raised burner with glowing embers and ember glass. Explore our vented gas inserts.

A vent free gas insert needs no chimney liner or vent pipe, and nearly all its heat stays in the room. The Innsbrook vent free insert works as a room heater and comes with a concrete or ceramic fiber log set and a blower. Its standing pilot version keeps heating in a power outage. Loft uses reflective crushed glass instead of logs. Check your local code before choosing ventless gas inserts.

A new fireplace or gas logs instead

If you are building a new wall, compare direct vent fireplaces and ventless gas fireplaces, or browse Empire's built-in gas fireplaces and all Empire fireplaces. To keep a real fireplace's open look, consider Empire gas logs.

Frequently asked questions

How do I know if I need a vented or a vent-free insert for my fireplace?

Choose direct vent if your chimney is sound and can take a liner. It gives you a sealed fire behind glass with exhaust outside. Vent free needs no pipe and keeps nearly all the heat indoors, but check your local code first. Both use natural gas or propane.

How long does a gas fireplace insert last?

A gas insert can last many years with yearly burner and pilot cleaning and checks by a gas technician. Keep the glass clean and the vent clear. Parts that wear can be replaced, including ignition parts, the blower and glass gasket. We can check availability for your Empire model.

Who makes the best fireplace inserts?

We do not rank brands. Choose an Empire fireplace insert from three direct vent looks: plain logs, tall flames or a raised burner with glowing ember glass. Two vent free looks offer logs or glass. All use natural gas or propane with a surround. Our inserts hub above shows other brands.
