Active Closed Loop Solar Water Heating Systems
Closed Loop Solar Heating Systems are suitable for single and multible solar heating application systems,e.g.domestic solar water heating,solar water heating hot tub,solar swimming pool heating or solar space heating systems.The Closed Loop Solar Systems are suitable for areas with questionable water quality and all climate conditions.The Closed Loop Solar Heating Systems are the preferred option for extremely cold areas.

Operation ¡ñThe controller(18) will switch on the pump when the temperature at the collector sensor TC is higher than the return temperature TR by at least the pre selected(delta T)amount.
¡ñThe pump circulates a heat transfer liquid around the loop.
¡ñHeat from the collector is transferred to the domestic water through the heat exchange coil in the tank.
¡ñWith the pump running,if delta T is not met,the pump will switch odd.
¡ñWhen a present tank temperature is reached at Tmax,the controller switches off the pump.
¡ñThe check valve(non-return valve)prevents heat from the tank fising towards the collectors should the tank be warmer(e.g.at night).
