Heliodyne Solar Hot Water for Cool Areasicon

If your region is prone to freezing, then a cool climate “closed loop” system is required. In these solar hot water kits a special non-toxic, freeze-resistant fluids is used, instead of water, to transfer the heat. This process protects your system from burst pipes during winter or cold nights and provides greater durability and trouble-free operation. A closed-loop system is also recommended in areas where the water is hard, since it prevents scaling in the pipes. It´s available in a flush or rack mount.

Benefits Heliodyne Solar Hot Water Kits Cool Climateicon

  • “Plug & Play” installation
  • Has all components included (less piping & storage tank)
  • Can often be mounted to existing hot water tank
  • Fully protected from overheating and freezing

The great benefit of the Heliodyne Cool Climate solar hot water kits is it´s efficient operation. When there is sufficient heat to be drawn from the collectors, the controller automatically activates the pumps. Heated solar fluid is then circulated from the collectors, through the heat exchanger, where its heat is transferred to water in the storage tank. The solar liquid is then pumped back to the collectors to once again be reheated. This circulation loop will continue as long as there is heat to be drawn from the collectors. During times when there is little or no sun, a backup heating system will be activated to provide adequate hot water.
