Key Technologies

Quadra-Fire Advanced Energy (AE) technology is a combination of efficient engineering and easy operation.

Automatic Combustion Control (ACC) is an advanced heat-management system from Quadra-Fire that maintains precision airflow for longer, cleaner and more efficient burns.

With Direct Vent Technology, your fireplace can use outside air for combustion, expelling 100% of the combustion exhaust and by-products.

Harman pellet stoves utilize an advanced Exhaust Sensing Probe (ESP) system to deliver precision heating control.

Direct vent FireBrick gas fireplaces and inserts provide the warmth and glow of a real wood burning fire without any of the inconvenience.

FireDome technology maximizes wood-heating efficiency and keeps the viewing area clean by directing airflow between the glass and fire.

FlexBurn stoves burn with or without a catalyst and achieve 15% higher efficiency on low burns with the catalyst in place.

Our unique, built-in thermostat requires no electricity and automatically adjusts the required air for combustion. Just set the stove for the heat output you want and let the thermostat do the rest. The result—longer, more even heat.

IntelliFire features intermittent-pilot Ignition (IPI) allowing you to conserve fuel and money when the fireplace is not in use.

The patented Pellet Pro System makes it possible to burn any grade of pellet fuel for maximum heat and efficiency.

Quadra-Fire wood stoves, inserts and fireplaces are famous for the patented “four-point” Quad Burn combustion system.

Our wood stoves utilize the latest in engineering breakthroughs to maximize performance and efficiency.

Power venting technology makes it possible to install a gas fireplace virtually anywhere.

PowerFlow redirects the flow of heat, sending the warmth where you want it.

Our top load technology is second to none and perhaps the most celebrated feature of Vermont Castings stoves. 

This climate control technology provides homeowners with the option to redirect heat output to specific areas of the home, improving heating efficiency.

Heat Management solutions allow you to enjoy the fire in comfort and at the same time control the heat.

WhisperTone technology allows airflow with minimal sound, the ability to horizontally terminate, and an automatic damper which stops air movement when the fireplace is off, thus preventing cold air infiltration into the home.
