Think of how much longer you could swim during the year if you added a solar heater to your swimming pool. A solar pool heater not only conserves energy and saves you money, but it is simple to add to your existing swimming pool filter system.

Step 1 - Choose A Solar Heating Kit

The main considerations when choosing a solar heating kit are the size of your pool and the power of your pool pump. Purchase a solar heater that is large enough to heat the amount of water in your pool. Compare the specifications of the solar heater to that of your pool pump to make sure your pump is powerful enough to push water through the solar heater efficiently.

Step 2 - Position the Solar Pool Heater

Where you set up your solar heater for your swimming pool determines how effectively it catches the rays of the sun. You can set it up on the ground near the pool, but if you do you have to worry about damage from walking on it. A better solution is to install it on top of your roof, on the slant if possible, and facing where it catches the most sun during the peak time of day.

Step 3 - Install the Solar Heater

Open the box carefully so you don’t damage the panel when you remove it. Roll the panel into position then follow the kit instructions to secure your solar heating panel to the roof. When the solar panel is secure, attach the inlet and outlet valves to the hoses you purchased, clamping each hose to its respective valve. Finally, with the pool pump turned off, attach the hoses to your pool filter system so that the pool water is forced into the solar heating panel after passing through the filter and pump, but before it returns to circulation.

Step 4 - Heat Your Swimming Pool

The solar heater is basically a mat that collects the warmth of the sun and heats the water in a series of channels before delivering it back to the pool. Run your pool pump during the hottest hours of the day for maximum efficiency and cover your pool at night with a solar blanket to retain the heat.

Step 5 - Solar Heater Maintenance

It is very important, especially if you live in a cold winter climate, to disconnect and store your solar pool heater before the temperature dips below freezing. If you allow water to freeze in the channels of the solar heater, it may cause damage to the panel.

If you own a swimming pool, a solar pool heater is a big step in the direction of energy conservation. Not only will a solar heater save you money by utilizing the earth’s largest source of renewable energy, but it may allow you to get more use out of your swimming pool.
