97% Efficient Hot Water and Heating
The Phoenix is a super insulated stainless steel water storage tank fitted with a combustion chamber submerged in the tank water. When the burner is fired, the hot combustion gases heat the combustion chamber walls, transferring the heat directly to the surrounding water. The hot gases travel into the secondary heat exchange coils where even more heat is transferred to the water condensing the combustion gases and wringing yet more heat from the gases. Finally the cool, low NOx combustion air is vented via plastic pipe to the outdoors.
