Does My Pool Heating System Need a Heat Pump?

by Celestial Solar | May 23, 2023



If you’re someone who loves to swim regularly in your pool, you know just how important it is to keep the water at a comfortable temperature. Traditional pool heating systems such as gas and electric heaters can be costly and energy inefficient. Enter heat pumps – a more sustainable and cost-effective option that can provide an upgrade to your pool heating system. Jumping into your pool doesn’t need to be a tall task. Explore the benefits of using heat pumps to keep your pool warm and inviting all year round and how they can be incorporated alongside solar pool heaters. Let’s dive right in!


What is a Heat Pump? 


A heat pump is a device that uses electricity to transfer heat from the outside air to your pool water, essentially acting as an air conditioner in reverse. Unlike gas or electric heaters, heat pumps do not generate heat. Instead, they extract it from the surrounding air and transfer it to the water. This makes them more energy-efficient, eco-friendly and cost-effective.


How Does a Heat Pump Work? 

Heat pump installation

A heat pump works by using a refrigerant cycle that involves four main components: an evaporator, a compressor, a condenser and an expansion valve. The process starts with the evaporator, which absorbs heat from the outside air and transfers it to the refrigerant. The compressor then compresses the refrigerant, which increases its temperature. The hot refrigerant then flows through the condenser, where it releases heat to the pool water. Finally, the expansion valve lowers the pressure of the refrigerant, which cools it down and prepares it for the next cycle.


Using a Heat Pump with Solar Pool Heating 


Solar pool heaters are another great way to heat your pool water, especially during the sunny months. However, they may not be sufficient during the colder months when the sun is weaker. By incorporating a heat pump into your solar pool heating system, you can ensure that your pool water remains at a comfortable temperature all year round. During the summer, the solar panels can heat the pool water, and the heat pump can maintain the temperature during the night or on cloudy days. During the winter, the heat pump can take over and heat the water using ambient heat from the air.

Heat Pump Benefits 


In addition to being more energy-efficient and eco-friendly, heat pumps have several other benefits:

Having fun in the pool

  • They are quieter than gas heaters, which can be noisy and disruptive.
  • They are more durable than electric heaters, which can corrode or malfunction over time.
  • They require less maintenance than both gas and electric heaters.
  • They have a longer lifespan than both gas and electric heaters.
  • They can be used alongside your solar pool heater!



Don’t worry if you’re concerned about not having enough space for solar panels when considering purchasing a solar pool heating system. Here at Celestial Solar, we offer heat pumps that can complement your solar pool heating system and compensate for any shortage of panel space.




If you’re looking to upgrade your pool heating system, a heat pump is a great option to consider. Not only are they more energy-efficient and eco-friendly than traditional heaters, but they also provide several additional benefits. By incorporating a heat pump into your solar pool heating system, you can ensure that your pool water remains at a comfortable temperature all year round.
