In the largest Kingspan solar thermal system ever specified in the USA, the team recommended installing 132 x Thermomax HP450-30 Evacuated Tube Collectors to provide hot water. The system was supported by custom Pump Skid comprising controls, duty-standby solar circulation pumps, duty-standby secondary circulation pumps, double wall heat exchanger to transfer the heat from the solar loop to the secondary DHW loop, telemetry, flow meters, etc.
The system is used to pre-heat 3 x 2,000 Gallon Tanks which feed the 3 x 4,000 Gallon DHW Tanks.
The annual solar contribution (T*Sol) is calculated as 1,223.4 MMBtu, with predicted annual CO2 savings of 188,043.22 lbs - equivalent to the CO2 absorbed by circa 3,900 trees per annum.
