Best Pool Heat Pumps

Your swimming season can be extended by weeks or even months with the help of a pool heat pump. Depending on utility costs in your area, a heat pump is a less expensive way to warm your pool water.

Pool heat pumps do not work in every climate and when temperatures drop below 45-50 degrees Fahrenheit, they can no longer convert heat from the outside air to transfer it to your pool water.

What is a Pool Heat Pump?

The main function of a pool heat pump is to draw in heat from the outside air that has been warmed by the sun. Your pool pump circulates the swimming pool water drawn from the pool, and then passes it through a filter, heat pump water heater and back.

What to Consider When Buying a Pool Heat Pump

Pool Size – The size of your pool determines the best pool heat pump for you. Basically, the larger your pool size, the larger your pool heat pump needs to be.

BTU – The most popular heat pump sizes are from 75,000 BTU to 125,000 BTU’s. For an approximate calculation follow this formula: pool surface area in square feet x temperature rise x 12. The result is the amount of the heat pump BTU output required. If your pool has an irregular shape, depth, or you are in an area of very cold nights, strong winds, or extremely low humidity you may want to consult a pool professional.

Efficiency – Choosing a pool heat pump that saves you money rather than doubling your electric bill is ideal. This means finding a heat pump that is compatible with your pool’s size is key. A pool heat pump that isn’t the right size could end up costing you a fortune because its working overtime to heat. You also want the heater you are buying to heat the pool quickly and to the temperature you prefer to save on costs.

Climate – Another thing to consider when looking for the best pool heat pump, is the climate where you live. If you live in a warm environment with plenty of sunshine, a heat pump should work great. However if you live in a place that temperatures drop below 45 to 50 degrees it may not be the most efficient.

Cost – Pool heat pumps are more expensive than pool heaters when purchasing. However, the cost to run a heat pump is much lower than the consumption of a gas heater. This makes heat pumps the most efficient way to heat your pool since they depend on sunshine, which is a freely available natural resource.

Noise Level –  Finding a pool heat pump that is noise-free or, at the very least, very quiet means enjoying your pool environment without disturbing your peace of mind or bothering your neighbors.

Installation – Before choosing a pool heat pump, consider if it will need to be professionally installed or if you can install it yourself. If it needs to be professionally installed, this is an added expense initially. Some types of pool heat pumps are easy to install while others will need the help of a professional.

Frequently Asked Questions

Should I leave my pool heat pump on all the time?

Unlike gas heaters, heat pumps are most efficient when they are running for long periods of time and often. Only running it when you use your pool means your pool heat pump will have to raise the water temperature by as much as 20°F.

What size heat pump do I need for my pool?

As a general rule, plan on 50,000 BTU of pool heat pump for every 10,000 gallons of pool water. You can also follow this formula: pool surface area in square feet x temperature rise x 12. The result is the amount of the heat pump BTU output required.

How long does it take a heat pump to heat a pool?

The answer depends on things like air temperature, heat pump size, swimming pool, current water temperature, desired water temperature, and if you also use a solar blanket. Generally a pool heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20°F.

What is the most efficient way to heat a pool?

A pool heat pump is a very energy efficient way to heat your pool with low running monthly costs ranging from about $50 to $150. When the outside temperature does not go below 45° F to 50 °F, the heat pump’s fan will draw in warm air and heat the pool, slowly. These units usually have a long life span of about 20 years but do have a high initial cost of installation.
