The Commercial Solar Water Heating range includes:

• Solar collectors: High efficiency copper absorber with a sputtered selective surface, maximising heat absorption and minimising heat loss with a glass wool insulation.
• Central heat store: Available in multiple sizes that can be interconnected to meet large demands, optimise available plant room space, and provide redundancy.
• Solar pump skid: Controls all the solar functions, including the 3-way valves and booster, and regulates the speed of the solar pump to optimise the flow rate through the solar collectors.
• Drain-back system: The heat transfer fluid drains back into the heat store when there is insufficient solar gain or when the maximum set service temperature has been reached.
• Heat exchange delivery skid: The control system varies the rate of energy transfer from the central heat store to precisely regulate the hot water outlet temperature to the building.

Booster options: Booster options exist to ensure constant hot water supply at times of low solar radiation or high hot water demand
