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.
