How does the EMPYRE work? 

The EMPYRE is a non-pressurized system eliminating any danger of explosion. The EMPYRE heats the water surrounding the fire chamber. The water is thermostatically controlled by setting the aquastat temperature setting at the desired water temperature. Pumps then circulate the hot water from the furnace to the buildings, and back to the furnace to be reheated. You can use a 3/4" - 11/4" pipe between the furnace and the buildings.

To distribute heat in a house or shop, you can choose from a variety of water to air heat exchangers. If you have an existing furnace with duct work already installed in the house you can simply install a square heat exchanger to let your current duct work do its work. If you do not have duct work in your house, you can also heat your house by running a 1/2" special hose between your floor joist, (approx. 12i") apart attached to the bottom of your wood floor. This 1/2" line loop would go into a bigger 1" - 2" pipe, called a header. A loop of 1/2" hose should be approx. 250' in length.

If you are making a concrete floor you would put a 1/2" hose in the concrete tied to the re-bar. The lines in a concrete floor are usually spaced 12"-18" apart.

See the following items that benefit from buying an Empyre furnace.
