Is a Heat Pump Water Heater Right for You? Find Out Here!

Heat Pump Water Heater

Are you wondering if a heat pump water heater (HPWH) is the right choice for your home? In this blog post, we’ll break down what a heat pump water heater is, its advantages over traditional tank water heaters, and why it might be a better option than a tankless water heater. We’ll also discuss the space and temperature requirements for HPWHs, as well as how to determine the right size for your needs. Finally, we’ll provide tips on choosing the right HPWH and finding an experienced plumber for installation.

What is a Heat Pump Water Heater?

To start, let’s clarify what a heat pump water heater is. HPWHs operate by extracting warm air from their surroundings and using it to heat water. They work similarly to refrigerators, which use coils and condensers to cool and freeze. HPWHs, also known as hybrid water heaters, have a condenser pump to transfer heat into the water and an electrical heating system for backup during high-demand periods.

Advantages of a Heat Pump Water Heater

One of the most significant advantages of HPWHs is their energy efficiency. They use 2-3 times less energy than gas or traditional electric water heaters, leading to lower energy bills. By replacing a gas water heater with an HPWH, you can reduce your carbon footprint while enjoying substantial energy savings.

Why Choose an HPWH over a Tankless Water Heater?

While tankless water heaters are popular for their efficiency, HPWHs have some compelling advantages. They are typically more affordable to purchase and install, especially if you can reuse existing HVAC and plumbing infrastructure. Even with installation costs considered, the long-term savings on your electric bills make HPWHs an attractive choice.

Space and Temperature Requirements

HPWHs require at least 800 cubic feet of surrounding air to operate optimally. This is roughly equivalent to a 10 ft. x 10 ft. room with 8-foot ceilings. Most installations are in basements, garages, or spacious storage rooms. The excess heat generated by the unit can also improve the room’s efficiency and even help dehumidify the air, reducing the need for energy-consuming dehumidifiers. Keep in mind that HPWHs perform best in a year-round ambient temperature of 40º–90ºF, making them suitable for basements in cold climates.

Determining Your Hot Water Needs

When selecting the right HPWH size, consider your first-hour rating or peak-hour demand. This is the amount of hot water needed during the most demanding hour, often in the morning or evening. offers a calculator to help you estimate your peak hour rating. Our experts at My Georgia Plumber can guide you in assessing your specific hot water usage patterns.
