40K BTU Without a Stove

Most of our customers are unfamiliar with what a heat exchanger is but the benefits of it are definitely worth knowing about. An open fireplace will have four options for heat output: an open fireplace with a grate, a heat exchanger, an insert wood stove, or an insert pellet stove.

If you are interested in keeping the open feeling of the fireplace but want more heat, the heat exchanger will fit the bill with approximately 40,000 BTU of heat output via a high efficiency variable speed blower.  If you have a grate in your fireplace the heat exchanger would replace this was a grate system that has a series of air channels that transfers the heat out a bar that runs across the bottom of the fireplace.

For the heat exchanger to work correctly a set of compatible doors must also be installed.  If interested in a heat exchanger we will take all necessary measurements to ensure a proper fit and go over door options with you to find a set that meets your requirements.
