Most people are thrilled with the prospect of converting sunlight into usable electric but there is another exciting aspect of solar and that is Solar Thermal.
Solar Thermal hot water systems use sunlight to heat your hot water, thus reduing the cost of your current energy consumption, whether it is oil, gas, or electric.
In its simplest form, a collector or collectors are discreetly located on your roof. The sun heats a closed loop system filled with a non-toxic freeze proof thermal liquid that runs through the collector and back down to a hot water heater where it heats your water. You will still have a back-up system heat source.
On a sunny day 2 or 3 collectors can provide all the hot water needs for an average family of four. With a system like this you could save up to 70% of your hot water energy costs.
