This proven and reliable technology will increase your home value and offer long-term performance and maintenance-free operation. In general, a properly sized solar pool heater will maintain 80˚ degrees or warmer all year under normal weather conditions.

Most solar pool heating systems in our area can be installed for $3,500.00 to $7,500.00 and will often pay for themselves in 2-4 years. Solar has no ongoing operational costs, so you will never have to turn your heater off due to high costs.

Why heat your pool with solar?

More Swimming

What good is a pool if it is too cold to use? Solar keeps your pool swim-ready all season long.

Save Money

We can’t predict the future price of your electricity, but we can guarantee you’ll never open a bill from the Sun.

Eco Friendly

Fossil-fuel heaters pollute the planet and deplete its natural resources. Solar is an emission-free and renewable source of energy.


Gas pool heaters need to be replaced every 5-7 years, heat pumps 7-10 years, and a solar heater has a 15-year expected service life.

How does solar pool heating work?

Diagram of how solar pool heating works. Cold water enters the top of the solar panels, heating as it moves downward through the pipes and ultimately back to the pool.

Solar pool heating is a simple process that collects free heat from the sun and transfers it to your pool. This technology uses black polypropylene collectors to absorb the sun’s heat and your existing pool equipment to circulate the warm water.

A manual valve or automatic solar control allows you to regulate the temperature. Stilwell’s solar pool heaters are fully customized specifically for your home and pool. We personally visit each home to ensure we have every detail to accurately design your solar pool heater using several factors:

 Pool size

 Pool orientation

 Roof material and vent location

 Temperature expectations

 Pool usage

 Control type

 Existing Pool Equipment
