The PH2-28 is an excellent water heating solution for average 2-bath to 3-bath homes.
The PH2-28ROFLP can support 2 to 3 major hot water applications in areas with a warm climate. It is not recommended for installation in areas with freezing climates. It can also be used for commercial use up to 185°F by adding a hi-temp computer chip.
Except for the label, this heater is identical to the Rheem RTG-95XLP. Paloma has owned Rheem since 1988.
