Custom Size Heaters cannot be returned nor exchanged. Please verify your measurements before ordering. This unit is a custom size.

The Fireplace Heater was developed to dramatically increase convection heat (hot air) coming from your fireplace. The unique design of this grate heater super heats the air within the exchanger tubes to over 500'F and will produce up to 50,000+ BTUs of heat, enough to heat a large room or two. It fits into most fireplaces and has a limited one-year warranty. The FHK Heater is easy to install; simply assemble the blower on the tubes, seal it with the supplied silicone sealer, and set into your fireplace.

The FHK Hearth Heater features heavy heavy-gauge aluminized steel tubes for long life. Its unique design still allows it to work during power outages by converting heat naturally through the tubing and into your home. The blower is connected to the grate by means of a flexible tube, which allows the blower to be positioned in front of the fireplace opening. Measures: 20-1/2" High, 20" Deep, 45" Front Width, and 37" Back Width.
