Solar Thermal installation can have issues with excessive heat production in the summer months, particularly if the system has been designed for space heating as well as hot water.

In order to manage excessive heat in periods of high solar gain and reduced energy usage, the heat needs to be safely dissipated.  Apricus provide a water to air heat exchanger specifically for this purpose.

Water returning from the solar collector can be directed through an HD-25 unit to dissipate most, if not all of the heat produced by an Apricus 30 tube collector in full summer sun. This is achieved by using a solenoid or thermostatic 3 way valve. The HD-25 may also be installed in a circulation loop, pulling hot water from the top of the storage tank and returning mind level, thus cooling the water.

The amount of heat the HD-25 is able to dissipate dependently on air flow, and the temperature differential between the hot water and ambient air.
