Heat Pump Water Heater

A heat pump water heater works by pulling warmth from surrounding air to heat your water, making it far more energy-efficient than traditional models. These systems can cut water heating costs significantly while reducing your home's carbon footprint. Whether you're considering an upgrade or need help with installation, Angi connects you with pros and resources to guide your decision.

Common Heat Pump Water Heater Service Questions

Yes, hybrid water heaters can be noisy — noisier than traditional water heaters. The sound they produce is often compared to the hum of a dishwasher. Its noise comes from the heat pump’s fan and compressor as they work to pull in and compress the air. While it’s not totally disruptive, especially if the unit is installed in less frequented areas, like a basement or garage, it’s something to keep in mind if you’re sensitive to noise or if the unit will be placed near bedrooms or living spaces.

One of the primary benefits of a heat pump water heater is how cost-effective it is. How much you save will depend on your water usage and electricity costs. That being said, we can ballpark savings for the average home of between $100 and $500 per year. You can increase that savings rate by researching and applying available energy incentives available in your area. If you really want to focus on cost, consider a tankless water heater.

A heat pump extracts warmth from the air around the heater with refrigerant. This is then compressed to a high temperature and, with the help of a heat exchanger, circulated through the water tank. The water heats up when contacting the heat exchanger. This is more efficient than standard water heaters as it uses already warm air instead of creating heat with gas or electricity.

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

Yes, a heat pump water heater can work in colder climates but it’s much more effective where it’s warm. The reason is that the heat pump needs ambient warmth in the air to compress. The less warmth, the more compression required, thus using more electricity and offsetting the energy-efficient benefits.
