Solar energy delivers DHW for garden centre
Andrews Water Heaters has supplied a solar water-heating system for the new award-winning Van Hage garden and leisure retail store at Peterborough Garden Park. Selected by consulting engineers Patrick Mills Associates, The Solarflow system preheats water supplied to two Ecoflo water heaters that supply domestic hot water for the entire building. Solar energy is expected to meet about half of the annual demand for hot water.
Five solar collectors are mounted on the pitched roof. They have a 95% absorption efficiency, 90.8% transmission and emission loss of only 5%. Preheated water is stored in a 700 l stainless-steel unvented cylinder as feed water for two Ecoflow water heaters, which each have a capacity of 230 l, an output of 41 kW and a recovery rate of 700 l/h through 50 K.
