Gas Fireplace Inserts

When you want the best of all worlds—convenience, low maintenance, and high heating efficiency—gas fireplace inserts are a home run. In addition to providing affordable, continuous heat, their blower fan makes them ideal for transforming your masonry or manufactured fireplace into a powerful, forced-air heating system. Unlike traditional open fireplaces that lose most of their heat up the flue, a modern gas insert converts nearly all its fuel into usable warmth for your home, significantly reducing energy bills.

Sweepnman sells, installs, and maintains gas fireplace inserts from the world's leading manufacturers, ensuring energy-efficient home heating. Our factory-trained and certified technicians provide professional installation services that comply with NFPA industry standards and local building codes throughout our southern NH and northern MA service area.

Gas Fireplace Insert Benefits

Installing a gas insert is a smart investment that yields many valuable returns:

Exceptional Energy Efficiency

Gas inserts are sealed-combustion appliances that retain most of the heat they generate in the firebox. This innovative design prevents conditioned room air from being lost up the chimney, achieving efficiency ratings of 70% or higher.

Push-button Convenience

Gas fires light instantly with a remote control, wall switch, or eFire app (select models). There is no ash cleanup, chopping wood, or hauling logs.

Powerful Zone Heating

The built-in multi-speed blower fan circulates warm air back into the room and surrounding areas, distributing heat effectively and allowing you to lower your central thermostat.

Better Indoor Air Quality

The sealed glass firebox provides better air quality than opposed to wood burning, protecting your indoor air quality while providing a clear view of the spectacular flames.

Authentic Experience

High-definition log sets, ember beds, and reflective liners create incredibly realistic flame presentations that rival the look of a natural wood fire.

Wood to Gas Fireplace Conversion

Is your old masonry fireplace inefficient, too messy, or used infrequently? A gas insert is the perfect solution.

“Inserts slide into the existing fireplace opening, transforming it into a new, high-efficiency heating system. It also requires less construction than installing an entirely new fireplace, making it a popular choice for home remodels.”
