Improved Efficiency

Burn Control: Converts an open fire into a closed system, allowing much better control of the burn rate.

Up to ~40% More Efficient: Installing the door can increase the efficiency of your back boiler system — meaning more of your fuel’s heat goes to heating your home and water, not up the chimney.

Extends Useful Heat: Converts energy that would otherwise escape into warmth circulating in the room.
