Gas Fireplace Inserts in Waukesha County,
An open fireplace can actually make your house colder, pulling warm air in and sending the heat straight up the chimney. A sealed gas insert keeps over 80% of the heat in your home, with no ash and no hassle. See working inserts among our 60 burning displays before you decide.

Gas Logs vs. Gas Inserts
Many people confuse gas logs and gas inserts, but they are very different products. Drag the slider to see a real insert transformation from one of our recent projects.
Gas Logs: Ambiance First
A decorative log set inside an open fireplace. Looks like a fire, but the unit is not sealed, so much of the heat still escapes up the chimney.
Gas Inserts: Real Heating
A sealed glass front with a liner system creates a closed combustion loop, drawing air in and venting out. A decorative furnace.
Over 80% Heat Retention
Sealed inserts keep the warmth in your home, while open fireplaces can pull more heat out than they produce.
Professionally Installed
Sized, sealed, and vented correctly by our installation team, and backed by our 1-year installation warranty.

Milwaukee Homeowners
"Excellent product. Efficient and tidy."
Great work. Replaced an older insert in our fireplace. I now can use the lower fireplace without bending to light the pilot. So happy with both American Heritage and Lopi products.
Insert Replacement
"Great service at a very competitive price"
I have been working with American Heritage Fireplace for many years, not only for my personal property, but referring many friends, family and clients. They provide great service at a very competitive price. Highly recommend.
Longtime Customer
"My experience with them was smooth"
I stopped by the store just to see their inventory. Rachel showed me the gas fireplace inserts that would best suit my needs, and Brian came to my house the next day to take measurements and explain options. The team was highly professional throughout. The temperature is below zero today and I am so pleased to have a warm fireplace.

Questions, Answered
What is the difference between gas logs and a gas insert?
Gas logs are a decorative set placed in an open fireplace: they look great but most of the heat still escapes up the chimney. A gas insert is a sealed unit with a glass front and liner system that keeps over 80% of the heat in your home. If you want real warmth, the insert is the answer.
Will an insert fit my existing fireplace?
In most homes, yes. Inserts are sized to fit into existing masonry or factory-built fireplace openings. Our in-home evaluation confirms measurements, venting, and gas line routing so you get a clear plan before any work begins.
How efficient are gas fireplace inserts?
Modern sealed inserts retain over 80% of the heat they produce, compared to an open fireplace, which can actually pull more warm air out of your home than it creates. Many families use their insert for zone heating and lower their utility bills.
Can I control the insert with a remote or thermostat?
Yes. Most modern inserts include remote controls, and many support thermostat control, so you get instant flame at the press of a button and consistent room temperature without tending a fire.
How long does insert installation take?
Most insert installations are completed in a day, including the liner system and finishing. Projects involving venting complexity can take longer; you will get a clear timeline in your installation plan.
Can I see working inserts before I choose?
Yes, and you should. Our Milwaukee showroom has 60 burning displays, including gas inserts, so you can compare flame styles and heat output in person before deciding.
