Solar Thermal Photovoltaics
|
Alistair Yardley of Purley wanted a solar thermal system to heat his DHW and then use any surplus for supplementary heating of his outdoor swimming pool. To connect to the swimming pool heat exchanger, Duosolar pre-insulated twin stainless steel flexible pipe was used outside the property. Three Eco-58-1800-30 were fitted giving a peak output of 4.5kW in full sun. This system is expected to provide about 3MWh (3000kWh) pa. The components of the system included: 3 x Eco-nomical 30 tube 58mm evacuated tube collectors Resol Flowcon A with BS4 controller (variable speed output) Resol SP1 18 Litre expansion vessel with mounting kit Inline airscoop 40 Meters of Duo-Solar pre-insulated stainless steel pipe 35 litres glycol Bowman pool heat exchanger Santon 250 litre twin coil unvented cylinder Swimming pool electrical relay and housing
Thanks to Alistair and Justin for this information.
