Heat pumps use electricity to transfer heat from the air into the water. This process works by using a refrigerant to absorb heat from the air and then transfer it into the water. 


  • They are typically very efficient and can be used in both warm and cold climates
  • Heat pumps also tend to be more affordable than solar pool heating systems
  • The water can be heated relatively quickly


  • Heat pumps can be noisy
  • They are not as energy efficient as solar pool heaters, so your operating costs will be higher
  • May require more maintenance than solar pool heaters

Solar pool heating systems use the sun’s energy to heat your pool water. They typically consist of a series of panels that are placed on your roof. These panels absorb the sun’s rays and transfer the heat to the water as it flows through them.


  • They will save you money in the long run as they are more energy efficient
  • They are environmentally friendly because they rely on renewable energy
  • Repair and maintenance costs are typically lower than with heat pumps


  • Solar pool heating systems can be costly to install
  • They usually require a well-insulated pool cover to work effectively
  • Your swimming sessions will most likely be limited by the amount of sunlight that your location receives
  • May take longer to heat the pool than a heat pump

There are both sides to the argument and it really depends on your needs as a pool owner. If you are looking for a quick and affordable way to heat your pool, then a heat pump might be the better option. 

However, if you are interested in saving money in the long run and being more environmentally friendly, then solar pool heating is the way to go. But, when it comes down to it, the answer may also depend on your specific needs and wants. 


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

This will obviously depend on the size of your pool and the temperature that you are trying to achieve. Another factor that comes into play is the size of the heat pump. But, on average, it should take around 6-8 hours to heat a pool with a heat pump.

Are pool heat pumps worth it? 

To gauge whether or not a pool heat pump is worth it, you need to compare the cost of running the heat pump against the cost of other heating options. In most cases, heat pumps are more affordable to operate than gas pool heaters. They also have a longer lifespan. So, in the long run, they can be worth to some pool owners. 

Which pool heater lasts the longest? 

If you are looking for a pool heater with a long lifespan, then you should consider a heat pump. These units typically last around 10-15 years. Solar pool heating systems also have a long lifespan and can last 20 years or more. This will also come down to how well you maintain your system. 

Does a pool heat pump need to be in the sun?  

In order for a heat pump to work more efficiently, it can be helpful to place it in an area that gets direct sunlight. This will help the unit to absorb more heat from the air and transfer it into the water. Although this is not a requirement, it can be beneficial. 


When it comes to heat pump vs solar pool heating, it really depends on your specific needs and wants. Heat pumps are typically more affordable and can heat the water relatively quickly. Solar pool heating systems are more energy efficient and can last longer, but they can be costly to install. 

In the end, the decision of which type of pool heater to purchase comes down to personal preference. Consider what your needs and wants are before making a final decision. Also, take into account the cost of installation and operating costs. This will help you to make the best choice for your situation.
