Eternal introduces two new retrofit-friendly hybrid water heater models, the Eternal GU125T and GU160T. The new units provide 125 gph (GU125T) and 160 gph (GU160T) of hot water. Designed for easy retrofit, the hybrids are half the size of a traditional 50-gal. gas water heater but almost double the industry output average of 83 gph. Both models run on 1/2” gas lines at 3.5” WC, vent with 3” PVC and have 75,000 Btu (GU125T) and 100,000 Btu (GU160T) of input. The units will be Energy Star-listed (pending) and capable of providing continuous hot water.
