Should I Buy A Solar Pool Heater Or Electric Pool Heat Pump

The choice between a solar pool heater and a pool heat pump depends on various factors, including your specific needs, budget, and your specific pool and home. Here are some considerations for each:

Solar Pool Heater:

  1. Energy Source: Solar pool heaters utilize energy from the sun to heat the pool water. They typically consist of solar collectors (panels) installed on the roof.
  2. Operating Cost: Once installed, solar pool heaters have minimal operating costs since they rely on free solar energy. They are considered one of the most cost-effective and environmentally friendly options in the long run. Only minor service costs for water leaks need to be considered for the 10-12 year system life.
  3. Effectiveness: Solar pool heaters work well in sunny climates and can effectively raise the temperature of the pool water. However, their performance can be influenced by weather conditions and the amount of sunlight available. There is a limit to how warm your pool will get, and it is highly dependent on the weather. You have to be willing to live within the performance envelope, which typically maxes out at 10-12 degrees over an unheated pool, perhaps more if you use a pool cover.
  4. Initial Cost: The upfront cost of installing a solar pool heater can be higher than some other options, but it often pays off over time due to lower operating costs.

Pool Heat Pump:

  1. Energy Source: Pool heat pumps extract heat from the air and transfer it to the pool water. They do require electricity to operate but are generally more energy-efficient compared to traditional electric resistance heaters, and are much less costly to operate than gas heaters, even if you have natural gas already piped to your house.
  2. Operating Cost: While pool heat pumps have a higher upfront cost compared to gas heaters sometimes, they may be less costly to install than solar pool heaters, unless you need to upgrade your pool equipment electrical circuits. They are known for their energy efficiency and can be more cost-effective to operate, especially in warm climates like Southwest Florida.
  3. Effectiveness: Pool heat pumps are effective in a variety of weather conditions. They work well in almost any conditions experienced in Southwest Florida, and can still operate efficiently when sunlight is limited, even in cloudy or rainy conditions.
  4. Initial Cost: The initial cost of a pool heat pump is often lower than that of solar pool heaters. However, the ongoing electricity costs should be considered in the overall cost of ownership.

The Ultimate Best Option

Pairing a pool heat pump with solar electric panels makes a lot of sense now. With solar panels coming down in price, using an electric heat pump pool heater and offsetting the electricity usage with solar electric panels can be a cost effective, efficient, and reliable heating option when compared to traditional solar pool heaters. The solar electric panels last twice as long as solar pool heating panels, and there is virtually no maintenance required.

Depending on your specific expectations and the suitability of your roof, we may recommend that you consider this option. There are also tax credits that influence the decision greatly since traditional solar pool heaters do not qualify for government incentives. Here is a great video on the subject explaining why you might consider a Solar Hybrid Electric Pool Heater, or SHEPH as we call it:

Which Option Is Best?

Ultimately, the best choice depends on your specific circumstances. If you have abundant sunlight and a great south roof with close proximity to the pool equipment, a solar pool heater may be a cost-effective and environmentally friendly option. If you need a solution that works in various weather conditions and have an ideal existing electrical situation, a pool heat pump might be more suitable. If you are concerned with ongoing operating costs and willing to make an upfront investment that will provide undeniable returns, a hybrid system with a heat pump and solar electricity may be best for you. Consulting with a solar professional can help you make an informed decision based on your pool’s characteristics and your preferences. Be prepared to let your consultant know what you expect in terms of heating performance and what concerns you have regarding the initial investment and ongoing operating costs.
