Solar Pool Heaters

Heating an average pool for the swimming season uses about the same amount of energy as most homes require per year. The costs go beyond just monthly heating bills when you consider greenhouse gas emissions involved. A solar pool heater pays for itself quickly.

Solar pool blankets (pool covers) are the cheapest way to reduce heat loss and save energy. You can also make your own solar pool heater, using a simple pump and some black PVC piping.


A solar pool heating system will cost between $2,000 and $4,000, depending on size, model specifications and options (e.g. automatic controls). Since you are saving energy, you may qualify for government financing incentives.


As with most solar power, the closer you are to the equator, the more energy you will get out of your system.

Almost anywhere in the world, a solar pool heater is a good investment.

No matter how much you think you know about solar, pool heating or electricity, we recommend that you choose a solar pool heating dealer.

System size and logistics

Typically, your solar collector should be at least half the square footage of your pool surface area. Have your collectors facing the sun. If you live in a more northern area, you will have one setting for your summer swimming fun. Those who live in warmer climes will need to adjust their solar panels with the seasonally moving sunlight.

How a solar pool heating system works

Your solar pool heater simply plugs into the existing filtration unit. You can choose the option of an automatic system which will have a controller and sensors to open and close a valve, deciding whether to send water back into the pool or through the collectors.
