Heat Transfer Products Inc. Condensing Water Heater
The new Phoenix gas-fired water heater from Heat Transfer Products Inc. is a sealed-combustion, direct-vent unit that operates with either natural gas or liquid propane and has a combustion efficiency of 96%. Side tappings in the jacket permit connections to a hydro-air system for space heating. In this setup, a pump circulates the heated water from the Phoenix to a heat exchanger in the ductwork to provide heat for the living space. The Phoenix is available in three sizes: 119 gallons, 80 gallons and 55 gallons. Each of these units offers two firing rates: 199,000 Btu per hour, modulating down to 66,000 Btu/h; or 130,000 Btu/h down to 44,000 Btu/h. Heat Transfer Products Inc. Circle 15.
