How A Solar Water Heater System Works
How it works….. The best solar water heater system for Florida. There are many types of Solar Hot Water Heater systems but in the Florida the flat plate solar panel that has best performance and therefore most common. The solar hot water panel has prism glass to magnify the sun and inside the solar panel is copper tubing with copper fins that are black (because black attracts and absorbs heat) to collect the heat…. The water is pumped from water tank to solar collector , through the tubes and down to tank again.. this keeps repeating until the sun is not available. The pump in our Solar Water Heater is powered by a small solar PV (solar electric panel) therefore it can produce hot water even when there is no electricity available. The system also includes a mixer valve that acts like a temperature regulator. If the water is too hot, the mixer valve will mix hot water with cold water. The solar water heater does include a electric element for times when it is not hot or sunny enough.

Does solar hot water work on cloudy days or cold days?
Solar is supplemented with a backup electric element… When it is cloudy or cold out it may not produce as much hot water.. the electric element will heat the hot water… Keep in mind that in Florida the whole day is not normally cloudy …. if its just cloudy in morning or part of day solar will still ad some heat to water… In Tampa, Florida area …. it is tropical weather here so for about 8-9 months of the year there is so much sun and heat that you can get enough hot water just with solar…. In coldest months homeowners use the electrical backup unit to add more heat to water…
