Heat pump water heaters use advanced technology to do the job with significantly less energy. In most homes they can be installed right where your current water heater sits. Take a moment to go through 4 simple installation considerations to figure out if a heat pump water heater is right for your home.
Why Choose an ENERGY STAR certified heat pump water heater?
- Save more than 50% on water heating energy costs – up to $3,500 lifetime savings for a family of four.
- Take advantage of utility rebates that may be available in your area.
- Products with the ENERGY STAR label are independently certified to deliver energy savings and help protect the environment.
Water Heater Replacement Guide
STEP 1: CHECK YOUR ELECTRICITY SUPPLY
Heat pump water heaters require 240-volt supply.
Do you currently have an electric water heater?
Not sure if your existing water heater is electric or gas? If your water heater does not have a flue, then it is an electric water heater with a 240-volt supply (see the images in Figure 1).
Figure 1: Conventional electric water heater without flue on left and gas water heater with flue on the right (exhaust flue circled in red).

STEP 2: Check for access to air
A heat pump water heater pulls in air from its surroundings to heat the water and releases cold air, so it needs access to plenty of air (See Figure 2).
Does your water heater location have:
A room air temperature that is greater than 40 degrees F year-round?
AND
Space that is at least 100 square ft. (10 ft. x 10 ft.) or a smaller space that can be fitted with louvered doors or ducted?
Figure 2: For spaces less than 100 square feet, talk to your installer about a louvered door and ducting system.

STEP 3: Check for head room
A heat pump water heater is a few inches to a foot taller than a conventional electric water heater and requires a certain ceiling height based on the size of the water heater – which is dependent on household size.
Does your water heater location have:
At least a 6 ft. high ceiling for a household of 5 or less members?
OR
At least a 7 ft. high ceiling for a household of 6 or more members?

STEP 4: Check for water drainage
Heat pump water heaters require proper drainage, since—like air conditioners—they dehumidify air and produce condensate that must be removed via a nearby floor drain, or another outlet using a small condensate pump.
Does your water heater location have access to one of the following?
- Floor Drain.
- Utility Sink.
- Sump pump.
- Existing drain pipe / line (Figure 3).
- Outside (only for locations that are above freezing all year round).

However, since ENERGY STAR certified heat pump water heaters are significantly more energy efficient than standard electric water heaters, it might be worth consulting a professional, just in case.
