Frequently Asked Questions (FAQs)
Take a look at some of the All About Pools team’s answers to some of the most frequently asked questions we get related to swimming pool heaters. If you have any additional questions, please reach out to us!
Are Pool Heaters Worth It?
Short answer, it depends on where you live and how long you want your pool to be in use during a calendar year. Check out all the options for how swimming pools are heated here.
Quality swimming pool heaters have the potential to be an incredibly worthwhile investment if a family wants to utilize its new pool year-round, or even just well into the school year starting in the fall. However, if your family only plans to use your pool in the hot days of summer, or if you live somewhere where the temperature is warm the vast majority of the year, a pool heating system is not as necessary.
How Do Swimming Pool Heaters Work?
How pool heaters work is firstly your swimming pool pump will circulate the pool water, the water drawn from the pool then passes through a filter, and then through the heat pump’s heater. Then liquid refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler swimming pool water circulating through the heater. The now heated water then returns back into the pool. The hot gas, as it flows through the condenser coil, returns to liquid form and back to the evaporator, where the whole pool heating process begins again.
Who Installs Pool Heaters?
We personally recommend you hire a pool heater installation service that is local to your area. Although it may be possible to install a pool heater on your own, it is recommended to hire a professional, especially for a gas or electric heater. Feel free to watch the short video below to see if you are capable of installing your swimming pool heating system on your own.
Why Does My Pool Heater Keep Shutting Off?
There are a few possible reasons for this, but the most common is a dirty filter. A dirty pool filter can cause low pressure and as a result, cause the pool heater’s pressure switch to turn off automatically. A dirty swimming pool filter can also prevent a pool heater from starting correctly and it can also cause your heater to shut off before warming the water fully. Some other possibilities are your heater motor not receiving the proper voltage, pool heater impeller malfunctions, and faulty switches.
What Size of Swimming Pool Heater Do I Need?
For example, if you have a 20 x 30-foot swimming pool, your pool has a 600 sq ft surface area. 600 divided by 3 is 200 and then 200 x 1000 = A minimum 200,000 BTUs heater recommendation.
How Long Does It Take To Heat A Pool Without A Heater?
It normally takes somewhere between 8 and 12 hours to fully cycle all of the water in your swimming pool, so factoring that in you can expect an overall temperature rise of 5 to 15 degree F after several days of sunny weather. Since we cannot control the weather of course, we usually do not recommend waiting for the sun to heat your pool. If you don’t have a pool heater, we recommend looking into getting one that fits in your budget.
How Much Is A Reliable Swimming Pool Heater?
Although we were able to find some swimming pool heaters around the $2000 range, the top quality ones were between $3000-$4000. Our team’s #1 pick that we reviewed is on the lower end of that range.

Hello, I am a writer and marketing specialist in Kansas City, MO.
