Heat up your simming pool with Solar Swimming Pool Heaters

Image how cool it would be to heat up your pool using a solar swimming pool heater. Number one you can significantly reduce swimming pool heating costs. The cost to install them is about the same as gas and heat pump pool heaters. But they have very low annual operating costs. Actually, solar pool heating is the most cost-effective use of solar energy in many climates.

How they work is not that complicated:

  • A solar collector — the device through which pool water is circulated to be heated by the sun
  • A filter — removes debris before water is pumped through the collector
  • A pump — circulates water through the filter and collector and back to the pool
  • A flow control valve — automatic or manual device that diverts pool water through the solar collector.

Talk to a contractor and see what they can offer.

Clear glass transmits up to 90% of solar radiation

Did you know that clear glass transmits up to 90% of solar radiation. It either absorbs or reflects only 10% of solar radiation.You would think since clear glass can transmit solar radiation in, it can also transmit it back. The beauty is that, it doesn’t, after solar radiation is transmitted through the glass and absorbed by the home, it is radiated again from the interior surfaces as infrared radiation.

Although glass allows solar radiation to pass through, it absorbs the infrared radiation. The glass then radiates part of that heat back to the home’s interior. In this way, glass traps solar heat entering the home. So that’s why many energy efficient homes have almost all glass walls or large windows.

Things to consider before you install a solar water heater system

Solar water heaters are great. They will save energy, money, and the environment. But before you buy and install a solar water heating system, you need to first consider your home’s solar resource. Not all homes are suitable for a solar water heater system. It all depends on how much sun light your home gets.

Solar water heating systems use both direct and diffuse solar radiation. Ideally, if you live in a sunny, dry, and warm climate, it’ll be great to install one. However, northern climate might still have enough solar resources. The most important is where your home is built. If it’s built in a heavily wooded area, then it’ll not work.

The best way for you to find out if not through guessing, but consulting a solar system supplier or installer. They’re trained professionals who can conduct a solar site analysis.
