Important Notice

As a company that shares your enthusiasm for the future of water heating technology, we want to provide you with a transparent assessment of the current state of heat pump water heaters. While these appliances show great promise, it’s important to be aware of some common issues that customers experience with the current generation of units, such as:

  • Excessive noise during operation
  • Electrical malfunctions
  • Questionable build quality
  • Design flaws
  • Inconsistent performance
  • Higher than expected warranty claims

As a company committed to customer satisfaction and standing behind every unit we sell, we feel it’s our responsibility to inform you of these potential drawbacks upfront. It’s important to note that we do not design or manufacture these units ourselves. We have no preference for your water heater’s fuel choice, and if you’re comfortable being an early adopter of this technology, we’re happy to assist you.

Based on industry trends and technological advancements, we anticipate that more refined and reliable heat pump water heaters will become available in 2024 and beyond. If your current water heater is still functioning and you’re not in urgent need of a replacement, it might be beneficial to wait for these improved models to hit the market.

What is a heat pump water heater?

A heat pump water heater is an energy-efficient alternative to traditional electric or gas water heaters. It uses electricity to move heat from the surrounding air into the water tank, rather than generating heat directly. This process is similar to how a refrigerator works, but in reverse.

Are heat pump water heaters more efficient?

When comparing heat pump water heaters to traditional gas water heaters, the efficiency question becomes more complex. Gas water heaters are generally less expensive to operate than electric resistance water heaters due to the lower cost of natural gas in most areas. However, heat pump water heaters use electricity more efficiently than electric resistance water heaters. In terms of energy efficiency, heat pump water heaters can be 2-3 times more efficient than electric resistance water heaters.

This means that they can provide the same amount of hot water while using significantly less electricity. When compared to gas water heaters, the efficiency advantage of heat pump water heaters depends on the relative costs of electricity and natural gas in your area.

If you currently have an electric resistance water heater and are considering an upgrade, a heat pump water heater can be an excellent choice for improving energy efficiency and potentially lowering your utility bills. However, if you have a gas water heater and are satisfied with its performance and operating costs, the efficiency gains from switching to a heat pump water heater may be less pronounced.

Heat pump water heater installation cost

The average heat pump water heater installation cost in Denver ranges from $4,500 to $6,000 or more, depending on factors such as the model, size, and installation complexity.

Are Heat Pump Water Heaters Reliable?

Heat pump water heaters can experience reliability issues, with some brands being more prone to certain problems than others. Here are some common error codes and issues reported by homeowners:

  • Error code EO: Compressor lockout due to high discharge temperature
  • Error code E4: High evaporator temperature
  • Compressor failures and leaks from the heat pump unit
  • AO Smith:

    • Error code A6: Compressor shutdown due to high discharge temperature
    • Error code A7: Evaporator freeze condition
    • Condenser coil failures and electronic control board issues


    • Error code 5: Compressor circuit open or locked out
    • Error code 8: Evaporator temperature sensor failure
    • Premature heat pump failures and noisy operation

    While these issues are not universal, they are more common than those encountered with traditional water heaters.

    Is a Heat Pump Water Heater Right For Me?

    A heat pump water heater may be a good choice if:

    • Your water heater is located in an unfinished basement or garage
    • You have solar power generation
    • You currently have an electric tank water heater
    • You live in a temperate climate

    However, if your installation space is limited, or if the unit would be located near living spaces, the noise and space requirements may be a concern.

    Pros & Cons of Heat Pump Water Heaters


    • High energy efficiency
    • Lower operating costs
    • Environmentally friendly
    • Potential rebates and incentives


    • High upfront cost
    • Reliability issues with current models
    • Noisy operation
    • Slower recovery times compared to
    • traditional tank water heaters
    • Requires more installation space
    • Reduced efficiency in very cold climates

    While heat pump water heaters offer energy-saving potential, their reliability issues are a concern. If your current water heater is functioning well, it may be worth waiting for manufacturers to address these problems in future models.
