What Is a Heat Pump Water Heater and How Does It Work?

A heat pump water heater, also known as a hybrid water heater, draws in outside air and passes it over an evaporator coil filled with liquid refrigerant. The refrigerant absorbs heat from the air, changing from a liquid to a gas.

The refrigerant gas then passes into a compressor, where it is pressurized to raise its temperature. Finally, the hot gas flows through a condenser (heat exchanger), transferring heat to the water in the tank.

Heat pump water heaters differ from regular units because they take heat from the ambient air and transfer it into the water. Regular water heaters generate heat with gas burners or electrical elements.

How Much Does a Heat Pump Water Heater Cost?

According to Today's Homeowner, heat pump water heaters cost around $3,600 (CAD 5,003) on average for the unit alone. Most homeowners spend between $1,200 and $6,000 (CAD 1,668 and CAD 8,338). For comparison, regular gas or electric tank water heaters cost between $400 and $2,100 (CAD 556 and CAD 2,918).

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

Professional heat pump water heater installation typically costs between $600 and $2,000 (CAD 834 and CAD 2,779), excluding the cost of the heater itself. Plumbers typically charge more for complex installations in confined or hard-to-reach areas.

Labor Costs to Install a Heat Pump Water Heater

Labor rates also vary significantly by location. Expect to pay more in places with a higher cost of living, as running a business is often more expensive in high-cost cities.

What Factors Impact the Cost of Heat Pump Water Heater Installation?

Various factors affect heat pump water heater prices, including the capacity and efficiency rating.

Tank Capacity

Small heat pump water heaters typically cost less than high-capacity units designed for large households.

A 40-gallon unit can supply enough hot water for up to two people and usually costs $1,200 to $2,000 (CAD 1,668 to 2,779). Meanwhile, a 50-gallon unit generally suits up to three people and costs between $1,500 and $2,800 (CAD 2,085 and 3,891).

Larger families or households with higher hot water requirements often require a 65-gallon heat pump water heater, which costs between $1,800 and $3,000 (CAD 2,501 and 4,169). 80-gallon units are the largest available on the market and cost $2,500 to $6,000 (CAD 3,474 to CAD 8,338) or more.

Efficiency Rating

The U.S. Department of Energy (DOE) measures the efficiency of heat pump water heaters using the Universal Energy Factor (UEF). A product's UEF shows how much of the energy it uses goes toward heating water. The higher the UEF, the more efficient the water heater.

Here's how much you should expect to pay for a heat pump water heater by UEF rating:

2.75 UEF: $1,200 to $2,000 (CAD 1,668 to 2,779)
3.0 UEF: $2,000 to $3,700 (CAD 1,668 to CAD 5,142)
3.25 UEF: $2,500 to $4,800 (CAD 3,474 to CAD 6,671)
3.5 UEF: $3,000 to $6,000 (CAD 4,169 to CAD 8,338)

Heat pump water heaters with higher UEF factors generally cost more than lower-efficiency brands. However, capacity usually affects the price more.

System Upgrades

You may need to upgrade your electrical or plumbing system before installing a heat pump water heater, which increases material and labor costs.

Heat pump water heaters almost always require a dedicated electrical circuit. Installing a new electrical circuit to accommodate the unit typically costs between $250 and $900 (CAD 347 and 1,251).

Depending on your existing setup, you may need to install new pipes to supply your fixtures with hot water. Pipe installation costs between $12 and $15 (CAD 17 and CAD 21) per linear foot. Expect to pay a plumber an additional $75 to $500+ (CAD 104 to CAD 695+) if you need to update your plumbing system to comply with current code.

How Much Can a New Heat Pump Water Heater Save on Energy Costs?

Energy cost savings with a heat pump water heater depend on the unit's efficiency and your household size. Energy Star estimates that homeowners could reduce their energy bills by up to $550 (CAD 764) per year by installing a heat pump water heater, saving up to $5,160 (CAD 7,171) across the unit's lifespan.

Are Rebates or Incentives Available for Heat Pump Water Heaters?

Certain incentives are available. Depending on your circumstances, you may qualify for a High-Efficiency Electric Home Rebate worth up to $1,750 or a Homeowner Managing Energy Savings Rebate up to $8,000 when you install an Energy Star-certified heat pump water heater. Some states and electric companies offer additional rebates or incentives for energy-efficient home upgrades.

Are Heat Pump Water Heaters Worth the Up-Front Cost?

Installing a heat pump water heater is often worth it because it can save you a significant amount on your energy bills, especially if you live in a warm climate. However, it may not be a worthwhile investment if you live in a colder area, already pay low electricity rates or lack the space to install a heat pump water heater. A tankless water heater may be a better fit for these circumstances.
