The honest answer

Solar pool heaters do work, and Florida is one of the better places in the country to use one. We have been installing and repairing them since 1999, and we would not do this work if the systems did not deliver.

But they are not magic, and the people who end up unhappy with solar pool heat usually fall into one of three groups. They expected hot tub water in January. Their system was undersized or badly placed on the roof. Or, most often, the system developed a small problem, the installer was gone, and it has been sitting shut off ever since. The first two are about expectations and design. The third is the one we fix most.

What solar pool heating does well

Panels on the roof that are not heating?

That is one of the situations we see most. AllSolar Energy repairs and takes over pool heating from any brand and any installer, including companies that are out of business. We have served more than 18,000 customers across 17 Florida counties since 1999.

Where it falls short

Why so many Florida systems stop working

You will see pool panels on a lot of Florida roofs, and not all of them are running. When we go out to look at those systems, the story is usually the same: a leak, a stuck valve or a controller problem, and a phone number for an installer that no longer answers.

That is not the technology failing. It is the service failing. A lot of those systems can be brought back with ordinary repairs. That is why this whole part of our site leads with repair and taking over abandoned systems, not with selling new ones.

How to tell if solar makes sense for your pool

A few questions get you most of the way there. Do you have a reasonably sunny roof area near the pool equipment? Are you hoping to extend the season rather than keep the water very warm on the coldest days? Will you use a pool cover? The Florida Solar Energy Center found that a cover retains more than two thirds of the heat needed to keep a pool at a comfortable swimming temperature, so it makes a big difference.

If you already have panels on the roof, the question is simpler: are they working? If not, start there. See how solar pool heating works for the parts, and call us if you would like someone to look at it.

Common questions

Do solar pool heaters really work?

Yes. They use the sun to warm pool water as it passes through panels on the roof, and in Florida they do a good job of extending the swim season. They depend on sunshine, so they heat less on cloudy days and not at night.

What are the pros and cons of solar pool heating?

The main advantages are free heat from the sun, low running cost, simple equipment and a longer swim season. The main drawbacks are that it depends on the weather, heats gradually, needs sunny roof space and has plastic parts that wear over the years.

Is solar pool heating worth it in Florida?

For many Florida homes it is, because of how much sun the state gets and how low the running cost is. It works best when the system is sized properly, a pool cover is used and the system is kept in repair.

Why did my solar pool heater stop working?

The most common reasons we find are leaks at the panels or header joints, a stuck valve, a controller or sensor problem, and weak flow from the pump or filter. Many of those are ordinary repairs.

Can solar heat my pool in winter?

It helps on sunny winter days, and many homeowners use it to keep swimming later into the year. For the coldest, cloudiest stretches, a backup heater or heat pump fills the gap.

Do solar pool heaters damage the roof?

A properly installed and maintained system should not. Problems usually come from leaks, worn mounts or roof penetrations that have not been checked in years, which is one reason we recommend an annual inspection.
