You step into the shower, ready to relax under a stream of steaming water — but what you get is lukewarm at best. If your water heater isn't keeping up with your household's hot water needs anymore, it may be time to install a new one.

As you consider your options, heat pump water heater installation costs can seem high. However, the long-term cost of ownership may be less with this more efficient option than with traditional or tankless water heaters.

What Is a Heat Pump Water Heater, and How Does It Differ From Traditional Water Heaters?

Traditional water heaters use heating elements powered by electricity or fueled by gas to increase the temperature of water in a holding tank. Heat pump water heaters pull heat from the surrounding air and transfer it to water.

Heat pump water heaters work based on the same principles as heat pump HVAC components. First, a fan pulls in air from around the component. The heat pump has refrigerant that absorbs latent heat from the air, which is there even in air that might feel a bit cool to you.

A compressor acts on the refrigerant, effectively squeezing it and creating pressure that increases the temperature further. As the refrigerant heats up, it converts from a gas state to a liquid state. The liquid refrigerant begins to move through a condenser coil that's wrapped around the water tank. The heat it brings is transferred to the water in the tank.

As the refrigerant cools because the heat it carries is transferred, it converts into gas and moves back through the process, absorbing heat again, being pressurized and heated by the compressor and cycling through the condenser coil as a liquid again and again.

How Much Does It Cost to Install a Heat Pump Water Heater?

The average cost of a heat pump water heater installation is $1,500 to $3,000 (CAD 2,100 to CAD 4,200). Depending on installation requirements, once you factor in the cost of the component, you may spend $3,600 to $6,500 total (CAD 5,040 to CAD 9,101).

What Are the Different Cost Factors Involved?

The exact cost of heat pump water heater installation varies based on factors like:

The brand and model you choose. Some brands and models cost more, and you typically pay more for high-efficiency appliances or those that integrate with smart home technology. However, these types of features can also help you save money via more efficient water and energy use, so it's important to consider the total cost of ownership.
Your geographic location. Heating, ventilation and air conditioning (HVAC) service and installation costs, and even heat pump water heater prices, can vary widely depending on your location.
The size of tank you need. Water heaters with larger tanks tend to cost more.
Where the installation occurs. If your water heater is in a space that's difficult to get to or work in, installation may take longer, increasing overall costs.
Previously installed components. When you choose a new water heater that requires upgrades or conversions, such as a switch from gas to electric power or vice versa, installation jobs usually take longer and require more parts. Some service providers also charge a fee for disposing of your old water heater.

The best way to understand the true cost of a heat pump water heater is to get a quote from a local plumber or other service company. Ask them to go over the quote with you so you understand all your options and how different choices impact your total cost.

Benefits and Downsides to Consider With Heat Pump Water Heaters

Heat pump water heater costs tend to be higher than traditional water heater prices, and they may cost more to install. If your immediate budget is tight, this may not be the best choice.

However, heat pump water heaters tend to be more efficient than their traditional counterparts. You may be able to save a few hundred dollars each year in annual fuel or utility costs associated with running the water heater. Heat pump water heaters have an expected lifespan of 10 to 15 years if properly installed and maintained, so those savings can add up to decrease your total cost of ownership.
