Heat Pump Water Heaters: The Pros and Cons

Updated: Mar 7

Water heating is an essential part of any modern household, accounting for nearly 20% of a home's energy usage. With costs soaring and energy efficiency becoming increasingly important, many homeowners are exploring alternative water heating options. One such option is the heat pump water heater, which combines advanced technology with renewable energy to produce hot water for homes. In this blog post, we'll explore the pros and cons of heat pump water heaters and help you decide if they're the right choice for your home.

Pros of Heat Pump Water Heaters:

1. High Energy Efficiency: Heat pump water heaters are designed to be highly energy-efficient, using around 50% less energy than traditional electric storage tank heaters. The reason behind this is because heat pump water heaters use electricity to move heat rather than generating heat themselves, which earns them the Energy Star rating.

2. Low Running Costs: In addition to being energy-efficient, heat pump water heaters have relatively low running costs. This can save you money on energy bills in the long run.

3. Durability: Heat pump water heaters are built to last. With proper maintenance, it could last for more than 20 years.

4. Environment-friendly: Heat pumps produce fewer greenhouse gas emissions as compared to other heating sources, which makes them friendly to our environment.

5. No Combustion: Without combustion, heat pump water heaters are safer than gas-fired water heaters.

Cons of Heat Pump Water Heaters:

1. Weather Dependence: Since heat pump water heaters absorb heat from the ambient air, their efficiency varies with air temperature. If the surrounding air is too cold, the water heater may not generate enough heat, significantly decreasing its efficiency.

2. High Upfront Cost: Heat pump water heaters are expensive to purchase and install compared to traditional water heaters. The installation cost usually depends on the accessibility of the homes' infrastructure and the size.

3. Space Requirement: Heat pump water heaters require more space than traditional water heaters because of their larger size.

4. Noise Level: A heat pump water heater can be noisy, especially when working at maximum capacity. However, new technologies have made improvements in decreasing the noise.

5. Technical Need: Heat pump systems which include computers, motors and refrigerants may necessitate specialized knowledge that you may not have.


Heat pump water heaters can be an excellent way to save energy and lower your home's carbon footprint. However, their benefits come with a few considerations. They are not suitable for all households and applications, demand enough space and expensive upfront cost. Before buying a heat pump water heater, ensure to know what you are buying and ensure you have a professional to install it. We hope this blog post has helped you understand the pros and cons of heat pump water heaters and choose the right option for your home.  If you have any questions, give us a call!
