Key Features & Technologies

Regency Fireplace WiFI App Control

App Control (Optional)

Adjust flames, heat output & more directly from your smartphone. This is an optional feature to control your Regency fireplace in addition to the remote and/or controls on the unit itself.

Direct Vent Fireplace

Direct Vent Technology

A direct vent fireplace has a completely sealed combustion chamber which allows it to vent directly out a side wall or through the ceiling of your home. The benefit of this system is that it brings in air from the outside of the home rather than using the room air.

Regency Fireplace Electronic Ignition

Electronic Ignition

Fireplaces with an electronic ignition system are used to start up and in the event of a power outage, Regency fireplaces will still work on battery back-up. Electronic ignition saves on fuel by not having the pilot light running when the fireplace is not in use.

Safety Screen 1

Safety Screen

Regency has integrated a custom designed safety screen into each faceplate design that meets or exceeds current North American safety legislation.


Variable Speed Blower

A blower will let you enjoy the warmth of your fireplace from any corner of your living space. The blower can dramatically increase the circulation of heat in your home.

Regency Fireplaces No Power

Power's Out - Heat's On

Never worry about being cold in a power outage. All Regency gas and wood units operate without electricity. Electronic ignition units have a battery backup system.

Regency Fireplace Warranty

Limited Lifetime Warranty

Quality is engineered into every component, from the heavy duty steel firebox to intricate laser cut decorative accents. Each Regency fireplace is backed by the most comprehensive warranty program in the industry.
