With one of these heat exchangers you can extract a larger percentage of the heat produced by your fuel, that is normally wasted and going up your chimney.

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. These 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 with velocity.

This adds conduction from the hot coal coals and convection from the flame, to the radiant heat of your fireplace. Recovering otherwise lost heat energy or BTU from the embers and flame of your fire. The standard blowers we use plug into a Common 110 VAC wall outlet (DC optional for solar panel, wind, solar cell, photo voltaic cell off grid or grid tie applications).

They are quiet running at a measured 50 db or less decibels, and are rated at 100 CFM each. With the option of a variable speed fan control, when mood is more important than heat output you can reduce the airflow for the perfect ambiance. Customers have commented how well the warmth generated by these heat exchangers can circulate to the adjoining rooms in your home.

A customer sent us many thanks when our grate prevented the freezing of his pipes in -20 weather when his natural gas furnace broke and the part was over a week away.

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