Buying Guide:

Similar to buying a regular pool heater or pump, it’s crucial also to have a list of things to consider to ensure you buy the right and the best heat pump pool heater. Here are the factors you need to consider to make sure you buy a model that meets all your needs.

Type and Size

Sizing the heat pump involves lots of factors. Typically, a heater is sized according to the swimming pool surface area and the difference between the pool’s temperature and average air temperature. Other factors include wind exposure, cold night temperatures, and humidity levels. That means pools located in areas with high average wind speeds, lower humidity, and cold nights require a larger heater.

A heat pump pool heaters output is rated with the total Btu output they produce. For you to calculate the amount of heat your pool needs, you have to determine your desired pool temperature. Then get the average temperature of the coldest months. Next step is subtracting the coldest months’ average temperature from your desired temperature, to get the temperature rise required. Next, calculate your pool surface area and use the following formula.

Pool surface are x temperature rise x 12 = total BTU required


The next thing you need to consider is the durability of the heat pump pool heater. You need to invest in a unit that utilizes corrosion and rust-resistant materials. The body casing needs to be weatherproof to keep the whole system protected from weather elements. Also, make sure that it utilizes a durable, robust heat exchanger for a long-lasting service.


Mostly, many people go for less-powerful models with the idea of lowering the energy bill. However, sometimes you the same unit might not as energy efficient as you might have thought. You need to get a model that utilizes modern technology to provide you with high heating performance while also maximizing energy efficiency.


Lastly, you need to buy a unit that you do not have to spend more money hiring a professional to install your pool heat pump. Some manufacturers make the process quite simple than others. If you’re planning of DIYing the installation, you might want to buy a model that provides easy installation.

Frequently Asked Questions (FAQs)

What is a heat pump pool heater?

A heat pump pool heater is an electrical pool heating and cleaning system that uses electricity to capture heat and move it to heat the water; it doesn’t generate heat.

How does a heat pump pool heater work?

As the pump inside circulates the pool’s water, these water passes through the filter and the heat pump heater. The heat pump uses its fan to draw hot air from the surrounding and directs it over an evaporator coil. Inside the evaporator is a liquid refrigerant that absorbs the heat from the absorbed air and becomes gas.

The hot gas is then passed through a compressor, which increases the temperature creating a hot gas that is passed through the condenser. The condenser then transfers the hot gas’s heat to the cold water that is circulating through the unit and returns to the pool while warm.


The fun of swimming in a clean and warm swimming pool is exceptional. When you get a right heat pump pool heater, you get to extend your swimming season as well as giving your swimming pool excellent maintenance. With all the above information, buying the best heat pump pool heater is a simple and straightforward process. So, pick a model that you believe gives you the best result, purchase it, and get to enjoy it.
