Are you wondering: how does solar heat work? As pool and spa equipment manufacturers, we’ve got quite a bit of experience in this area and can make it simple for you! A solar heating system is composed of two main elements - collectors and circulation systems. Basically, something to collect the water and allow the sun’s energy to warm it, and a way to move that water through the system and make it available for use.
Let’s take a look at these two main components to solar water heaters:
Collectors (evacuated tube, batch, and flat-plate) - which method does the system use to collect and/or store any water being heated, or hot water ready for use?
Circulation systems (forced circulation, passive, direct, and indirect) - the other main aspect to a solar heating system is how the water is circulated through the system. Some use pumps to push water through, while some need no pumps because it used the water pressure from the city or well, and the water is moved through on its own as it heats up. Others circulate directly through the collectors - getting warmed by the sun immediately, and either used right away or sent to a tank to wait to be drawn.
Which Type of Solar Heat Works Best?
We might be a little biased, but after more than 15 years in the pool and spa industry, we’ve actually patented our own technology that we feel is the best value on the market. They are called Thermocraft solar panels, and it costs virtually nothing to use. Significantly cheaper than an electric pool heat pump, our solar panels will keep your pool warmer longer than other systems, and you’ll be doing your part to lessen your carbon footprint.
Does Solar Heat Cost Money?
Once you’ve set up your Thermocraft solar panels, there is minimal expense to using your solar heat system! In fact, per the US Department of Energy’s website, you can get your initial investment back in as little as one and a half years, depending on local fuel costs. Our clients have reported incredible return on investment, with almost no operating costs year-round. Try out our solar heat calculator and find out how affordable it is to have solar heat for your pool!
How Long Do Solar Panels Last?
They tend to outlast their predecessors such as gas and heat pump pool heaters. Most homeowners can hope to get around 20 years of useful life or more out of their system. Imagine saving massively on your utility bill for the next two decades while enjoying your warm pool throughout!
