SIMPLE SOLAR.

Solar water heating is simple and relatively inexpensive. Yet the two basic uses for hot water, for space heating (a warm home) and domestic hot water (a hot shower) are quite different.

A hot water space heating system using radiators, baseboard heating, or in-floor radiant heat is a closed system using water that flows in a loop under low pressure.

Hot water that is used for a bath or a brought to boil for a cup of tea must come in fresh from the street, or well, under high pressure, and is of course consumed.

Instead of having two systems, and the incurring expenses, PowerTech Solar has developed a heat exchange system that would allow one thermal solar collector system to make hot water for both space heating and domestic use. The company is looking for partners particularly in the U.S. to further develop and market the technology. Visit PowerTech at http://www.powertech-solar.com/ .
