Water is much colder than you might expect. The temperature can vary depending on the season, the location, and the depth, but even in the middle of summer, the temperature of your pool water is likely to be around 68 F.
In order to enjoy your pool for swimming, you need to heat the water to at least 80 F, but most people prefer the water to be in the mid-to high 80s.
The type of pool you have and how you heat it will affect how much it costs to heat your pool water.
We researched dozens of the most popular pool heaters currently available, evaluating them based on effectiveness, longevity, and ease of installation and use. Our top pick, the Hayward ProSeries SP1515 15,000-BTU Pool Heater, is easy to install and ready to use right out of the box.

Best Swimming Pool Heat Pumps Buying Guide
Before choosing the best swimming pool heat pump you should consider the following options:
1. Power Consumption: One of the most important aspects to consider when buying a swimming pool heat pump is power consumption.
The higher the power consumption, the higher your electricity bills will be. The ideal pool heat pump will have a low power consumption so that your bills don’t go up.
In general, the more efficient the heat pump, the higher the annual operating cost. This is because the energy is extracted from the surrounding environment, which has a low temperature, and therefore requires more energy input to heat the pool water.
You can find the power consumption of a heat pump in two ways. First is the energy efficiency ratio (EER). The higher the EER, the lower the operating cost.
The second way is the input rate measure (IM). The lower the IM, the lower the operating cost.
For example, if a heat pump has an EER of 8 and an IM of 1.8, then the operating cost will be half that of a heat pump with an EER of 10 and an IM of 2.0.
The higher the EER or IM, the lower the operating cost. Therefore, the ideal heat pump will have a low EER and IM.
Things to note:
The EER is calculated based on the pool water temperature of 35 degrees Celsius and the air temperature of 25 degrees Celsius. Therefore, the EER is different from the energy efficiency label (EFL) on the heat pump.
The input rate measure is calculated based on the water temperature of 20 degrees Celsius and the air temperature of 30 degrees Celsius. Therefore, the IM is different from the energy label on the heat pump.
The EER and IM are calculated based on the standard operation mode of the heat pump, and therefore, the real energy consumption will be higher than the standard operation.
2. Capacity: You need to purchase a heat pump that can meet the temperature requirements of your swimming pool. The ideal heat pump will have a large capacity so that it can heat the water in a short period of time.
The larger the capacity, the higher the energy input and operating cost. Therefore, you should purchase a heat pump with a capacity that meets your needs but doesn’t exceed them.
What else you should know about the best swimming pool heat pumps
1. What are the best swimming pool heat pumps?
Some of the best swimming pool heat pumps on the market include the Hayward HeatPro HP21104, the Pentair UltraTemp 70, and the Jandy LXi.
2. How do swimming pool heat pumps work?
A swimming pool heat pump is a device that uses the heat from the air to heat the water in a swimming pool. The heat pump consists of a compressor, a condenser, and an evaporator. The compressor pumps the refrigerant through the system. The refrigerant absorbs heat from the air and transfers it to the water. The water is then circulated through the pool.
3. How do I choose a swimming pool heat pump?
There are a few things you need to consider when choosing a swimming pool heat pump:
1. The size of your pool – you need to make sure the heat pump is powerful enough to heat your pool.
2. The climate you live in – heat pumps work best in warmer climates.
3. Your budget – heat pumps can be expensive, so you need to make sure you can afford the one you want.
4. How do I install a swimming pool heat pump?
Most swimming pool heat pumps come with easy-to-follow installation instructions. In general, you will need to install the heat pump near your pool, connect it to a power source, and then connect it to your pool’s filtration system.
5. How do I maintain a swimming pool heat pump?
The best way to maintain a swimming pool heat pump is to regularly check and clean the filters, as well as the coils. You should also make sure that the pump is properly lubricated and that the unit is free of any debris.
Conclusion
On the market, there are numerous best swimming pool heat pumps. Hopefully, the list of the top ten best swimming pool heat pumps will save you time researching and deciding on the best one for you.
