Frequently Asked Questions
How many degrees will a solar heater actually raise my pool water?
You can typically expect an increase of 3 to 10 degrees Fahrenheit. This depends heavily on the amount of direct sunlight and the ambient air temperature. On a very hot, sunny day, you will see the best results. If it is cloudy or windy, the heat loss from the pool surface will likely outpace what the panels can collect.
Do I need to keep the heater running at night?
Definitely not. Running your pump and heater at night will actually cool your pool down because the panels will act like a radiator, releasing heat into the cool night air. Only run your solar system during the peak sunlight hours, usually between 10 AM and 4 PM. This keeps your energy bills low and your water temperature high.
Is a solar cover necessary if I use a solar heater?
A solar cover is the most important accessory you can add to your pool. Without one, you lose the vast majority of your heat through evaporation at the surface. Think of the heater as a faucet adding warm water and the pool surface as a drain. A solar cover plugs that drain so your heater does not have to work twice as hard.
Will these heaters work with my saltwater pool?
Most solar heaters are perfectly fine for saltwater systems. Just check that the mounting hardware and clamps are made of stainless steel or high-grade plastic. Cheap metal components can corrode quickly when exposed to saline water. Stick to reputable brands that specify their units are compatible with salt chlorination.
How long should a decent solar heater last?
With proper care, a quality solar heater should last 5 to 10 years. The biggest threat to their lifespan is winter damage. If you live in a cold climate, you must blow out the lines with an air compressor before the first frost. Leaving water in the panels during a freeze is a guaranteed way to ruin the system.
