A. Electric hybrid water heaters come in different sizes. The most common size currently on the market is 50 gallons.

Q. Should I add an insulating blanket around my electric hybrid water heater?

Manufacturers do not recommend adding an insulating blanket to an electric hybrid water heater. Unlike older water heaters, electric hybrid water heaters have thick insulation around the tank, so the water inside only loses 8% (or 10 degrees Fahrenheit) of its heat in a 24-hour period. The addition of an insulating blanket also introduces the risk of blocking the heat pump’s air intake and outlet, which can cause damage and keep your water heater from working properly.
