An Evacuated Tube Collector (ETC) is a solar water heating system that is based on efficient solar collector technology. It uses conductive glass tubes to absorb heat from the sun, which is then transferred to the water or other circulating fluids. An ETC consists of a number of glass tubes that are made of borosilicate or soda lime glass.

Installing Solar Water Heating at CAT, How many panels or tubes will I need? As a rule of thumb, you’ll need about 1 square metre per person to give enough hot water in summer. For flat panels this usually means one panel for a small household, or two panels for a large one.

Evacuated tube solar thermal systems work by absor direct and diffuse solar radiation and transferring into a heat energy than can be used to heat your hot 

Closed-loop, or indirect, systems use a non-freezing liquid to transfer heat from the sun to water in a storage tank. The sun's thermal energy heats the fluid in the solar collectors. Then, this fluid passes through a heat exchanger in the storage tank, transferring the heat to the water. The non-freezing fluid then cycles back to the collectors.
