Solar thermal panels evacuated tube.

Evacuated tube solar collectors operate in a different way from the collectors presented so far. Evacuated tube solar collectors heat pipe collectors a heat pipe evacuated tube collector uses alcohol or water in a vacuum which is used to absorb the sun s energy. Geoff harding has been awarded the hoyt clarke hottel prize by ases for 2008. Flat plate and evacuated tube solar collectors are mainly used to collect heat for space heating domestic hot water or cooling with an absorption chiller in contrast to solar hot water panels they use a circulating fluid to displace heat to a separated reservoir.

On may 5th there was good news from the solar 2008 american solar energy society ases solar congress held in san diego california state usa that chief scientific consultant of sunrain group dr. Strangely enough many people weigh in and take different sides. Harding for his research and development of evacuated glass solar thermal collector. These usually consist of a heat pipe inside a vacuum sealed glass tube.

Like a red sox vs yankees type of rivalry it s a heated debate. This vapour then rises up the. A typical evacuated tube solar collector system will cost about 3 000 5 000 to get installed on your property and will typically produce about 1 000 2 500 kwh of useful heat or about 50 of your hot water requirements. As the area of one tube is small to increase the heat collection area a number of tubes are connected to one manifold although just one tube is shown in fig.

The manifold has been cut away to show the internal copper pipe work which the tubes push into and the insulation around it to prevent heat loss. Due to the vacuum the alcohol or water will evaporate at a low temperature of 25 c to form a vapour. 8 depending on the collector size 10 20 tubes are used. The evacuated tube solar collector consists of a set of cylindrical tubes.

Viessmann s evacuated tube solar collectors offer a highly effective way to harness the sun s energy to provide hot water for your home. This is an incredibly common question in the solar thermal industry. The cost and potential returns for an evacuated tube solar system. Solar thermal collectors heating water.

By installing these solar thermal collectors on your property you stand to reduce your energy bills and cut your carbon footprint.
