How Can I Make My Swimming Pool Heat Pump More Energy Efficient?

Customers often come to us and ask “how can make my swimming pool more energy efficient?” This is a great question, especially considering how rough the economy has become recently. In this article, we explain a few ways you can easily reduce your heating costs.


  1. Select the right heater for your pool: Some heaters have higher upfront costs and lower maintenance costs, while other have lower upfront costs and higher maintenance costs. Learn more about different types of heaters here.
  2. Take advantage of solar heating: By pairing solar panels with your heater, you can drastically reduce your heating costs. Solar panels have minimal operating costs, are environmentally-friendly, and give you access to free heat!
  3. Run your pool pump when you turn off your heater: When your pool pump is running, the pool water is constantly circulating and has a consistent temperature throughout the swimming pool. In contrast, when your pool pump is not running, warmer water rises to the top of the pool while colder water sinks to the bottom. The surface temperature will be higher when your pool pump is not running. This “layering” of water temperatures accelerates heat loss from the pool.
  4. Use a solar cover when you do not use your pool: We always suggest solar covers to our customers because they drastically reduce swimming pool heating costs. 75% of a swimming pool’s heat loss is due to evaporation. A solar cover minimizes evaporation by acting as a barrier between the pool water and the air. In fact, by using one, you can reduce your swimming pool heating costs between 50-70%.

  5. Maintain your heater correctly: Maintain appropriate water temperatures when your pool is in use – 78° to 80°F (26° to 27°C) for active swimming and 80° to 82°F (27° to 28°C) for recreational swimming. Lower the water temperature when your pool is not in use. By lowering your water temperature 1°F (0.6°C), you can save 10% to 30% in heating costs per month.

By following any of these tips, you can have the best of both worlds: lower swimming pool heating costs and a heated swimming pool. How do you keep your swimming pool heating costs down? Leave your thoughts in the comments section below!

  1. Choosing the right type of pump is important and factors such as the size of your pool, type of filtration and sanitation system, and how often it’s used should be considered. Installing the best pump for your pool will ensure that your pool runs at its best – this means easier maintenance, lower energy costs and longer equipment life.

  2. Swimming can also be beneficial for children and adults who suffer asthma. Bear in mind though, that swimming in indoor chlorinated swimming pools can make asthma symptoms worse. It’s best to swim in a well-ventilated, or outdoor swimming pool if you suffer asthma. And to ask your doctor before starting any kind of workout routine.

  3. Do you have a write-up procedures for winterizing my heat pump, model 120ARDSBMN I have been closing my pool for over 20 years, but when we moved and had a pool put in last year, we purchased one of your heat pumps. We live in Pa. so it is obviously important that i flush out the pump properly for the winter months. Thanks

  4. Hi. I have a new install of a AquaCal SQ166. The unit is not going into freeze protection mode and Defrost Mode. As a result the unit is freezing the coil. I have tested the unit ability to go into defrost mode at temperatures ranges from 35, 40, 45, 50 degrees and unit does not prevent coil freezing. I purchase the unit specifically because of its ability to operate at near 20 degrees and it is not functioning anywhere close to this temperature. I suspect the defrost temperature sensor is not functioning properly. I less suspect a calibration at this point. Please note that I can operate the unit properly at 50 plus degrees with no problems should I chose too. I also have a 350,000 gas unit to supplement heating. Please note that I clearly understand the efficiency of the unit as the temperature lowers. However, I’d would like to insure that the SQ166 operates properly, and somewhere near or at 20 degrees. What do you recommend as the next step in the resolution of this problem.
