Where the water heater would sit
ENERGY STAR’s product page lists interior spaces that stay within a temperature range all year, with a stated volume of air around the unit, and it suggests “a space with excess heat, such as a furnace room” where possible. For colder environments it describes a temporary back-up electric mode in colder months, and adds: “This will increase energy use during these months.” (Undated product page, read 2026-11-09, United States.)

For humid months it adds that “the water heater can help cool and dehumidify the space it is installed in.” It gives no single verdict for every home.

Plan the installation ahead
The product page adds: “Your installer may need time to order the proper model, and it may take longer to install than a standard water heater.” For sizing, it gives this starting point: “Use the gallon capacity of your current storage water heater, if you already have one, as a starting point.” (Undated product page, read 2026-11-09, United States.)

Before requesting bids, note the room where the present water heater sits, whether that room stays warm or cold through the year, the open space around the tank, and the tank size on its label. Ask each contractor to state in the written scope where the new unit would go, how long ordering and installation may take, and what the annual maintenance includes, such as the air filters the product page mentions.
