Quite honestly Solar heaters are a bad idea. Solar heaters are only as good as the sun around them. In other words, if your roof does not sit in the sun the entire day, or at least during the 8 hours when you would have your swimming pool on, don't even waste your money. Also.... If you have a stretch of 3-4 days when we get rain showers, you are not gaining any heat from the solar panels as there is no sun to heat up the black panels, so over the course of the 3-4 day span, it might take you 3-4 days just to get back to where you were. At least with a Heat pump, or a gas fired heater, you can still run your heater regardless of the weather conditions and keep your pool at the temperature you want. Also. Like everything else... Solar heaters will continue to heat as long as you run the water through them, with a heat pump you can physically set the temperature you want, or a gas heater you can set it for the desired temperature level. If you go away for a few days, and forget to shut off the water to the solar panels, you could come back to water that you may find to be unsuitable for your likes. But as you said... you don't get direct sunlight on your roof all day, i wouldnt even WASTE any money on a product that is not going to give you the results that you want. the other thing with solar heaters like this, if your house if 40 feet from the pool. you are going to need 100 feet of additional plumbing work to be installed. to get the water to and from your roof, and on the return trip to the pool, since your plumbing will be inground, the water will lose some of the heat that it generates from the panels through the plumbing having to travel 40 feet just back to your pool. At least with a heater next to your equipment, your water is only traveling a few feet or a substantially less distance to your pool therefore reducing any loss due to the travel back to your pool. |
