Is this the right size?
A 65-gallon heat pump water heater typically suits 3 to 5 people, and is a common upsize when replacing a 50-gallon gas tank because heat pumps recover more slowly. Heat pumps recover more slowly than gas or electric resistance tanks, so many installers size up one step. Use the first-hour rating to compare against your peak-hour demand.
