Solar water heating collectors capture and retain heat from the sun and transfer this heat to a liquid. Solar thermal heat is trapped using the “greenhouse effect,” in this case is the ability of a reflective surface to transmit short wave radiation and reflect long wave radiation. Heat and infrared radiation are produced when short wave radiation light hits a collector’s absorber, which is then trapped inside the collector. Fluid, usually water, in contact with the absorber collects the trapped heat to transfer it to storage.
Two principles govern solar thermal collectors. First, any hot object eventually loses its heat back to the environment. The efficiency of a solar thermal collector is directly related to heat loss, mainly from convection and radiation. Thermal insulation is used to slow down heat loss from a hot object to its environment.
Second, heat loss is more rapid if the temperature difference between a hot object and its environment is larger, in this case between the temperature of the collector surface and the ambient temperature. Solar is an excellent clean energy source its fuel, sunlight, is limitless, free and emits nothing when converted into energy. The problem with solar, as most of us know, is its efficiency.

A solar water heater uses the renewable thermal energy produced by the sun to warm water for your shower, washing machine, and dishwasher. Better yet, it does it at a fraction of the price of a conventional storage tank water heater. If you take the plunge and purchase a solar water heater, expect to see your home’s water-heating bill cut in half. The liquid is heated in the solar lovers and returns through pipes to a storage container, where a heat exchanger inside the container transfers the heat to the water. Most systems rely on electric pumps to move water between the storage container and the rooftop solar lovers.
In general, solar water heaters can be used anywhere as long as your roof gets sunshine for most of the day. The rooftop lovers should face south. A direct system makes sense in warm climates where temperatures don’t fall below freezing. The non-freezing liquid used in an indirect system makes it better suited for cold climates.
NTT Heating qualified solar water heating system can cut your annual hot water costs in half, and is generally designed for use with an electric or gas back-up water heater.
