DURACORE SOLAR

SOLAR HEATING // HOW OUR SPA COVERS WORK

DuraCore's unique construction allows the cover to actively move heat in and out of your spa. You can add built-in solar heating to the Classic by selecting the Solar model, then save up to 80% of your spa's heating costs. Here is how it works.

Bringing the sun into your spa

As the sun’s rays warm the top of the cover, fans powered by small PV panels circulate air inside the cover between the top and the bottom. The solar heat warms the bottom of the cover up to 160 degrees F, then the heat radiates directly down to the water in the spa, the same way a fireplace can warm you from across the room. The cover gets very warm, but it's always safe to touch.

US Patent Pending

Two small fans inside each side of a DuraCore solar cover circulate air in small passages right under the top and bottom of the cover. An electronic controller allows you to set your preferred temperature for the fans to turn off so your spa doesn't overheat. The standard setpoint range is 95-104F. If you have a swim spa and need a lower setpoint, we can customize the control for you.

The custom electronic controller that manages the water temperature also lets you know how your SunCatcher is doing. A status LED flashes to let you know when the fans are running, and SunCatcher also shows you just how much energy you are saving at any moment.

The controller also keeps track of how much energy you have saved over the life of your cover, so you can gain satisfaction for what you are doing to help the environment.

Only a small amount of electricity is needed to power the small fans inside the cover. This can be provided by small PV panels attached directly to the top of the cover, or by an externally mounted PV panel with a 30 ft cable that attaches to the cover. Contact Modern Spa Cover sales for details.
