When you use one of our tubular fireplace grates in an your fireplace, you will realize a saving on your heating costs and a reduction in the amount of firewood you burn to keep warm. With one of these CFI fireplace doors you can extract a larger percentage of the heat wasted and going up your chimney. Our Heat Exchangers are designed with the greatest surface area to capture and move into your home the highest percentage of the BTU/KWH heat generated by your fire.


All our products are made with fully welded uncoated non-galvanized structural grade industrial carbon steel, and UL certified electrical components.

Here is how it works:

Our all steel design uses several perfectly sized heavy duty thick wall tubes for maximum heat exchanger surface area, superior airflow volume, minimum burn through, and maximum combustion area volume. The tubes are welded together forming a channel that is filled with cool home air. The tubes then heat the air as it passes through them. Hot air is then blown back into the your home. The added conduction from the hot coals and convection from the flame, recovers otherwise lost energy or BTU from the embers and flame of your fire.

These serve to increase the comfort of your entire home, conserve the amount of wood you burn, and nearly eliminate the need for other expensive methods of climate control such as electric heaters, heat pumps, corn or pellet stoves, and central air oil or gas furnaces.


LTL liftgate freight shipping service to your door is included in the price.
