Forced Circulation Systems

Sometimes known as pumped, split or forced circulation, these systems typically have the storage tank separated from the solar collectors, with the tank located at ground level and the collectors on the roof. Individual homes A pump and control unit are utilised to ensure correct water circulation. This allows the collectors to be situated away from the tank. For example, the tank may be situated in a basement while the collectors remain on the roof. Unlike uncontrolled thermosiphon systems, there is no chance of wasting water from overheating because the solar controller automatically stops the water circulating once the storage tank is full of hot water. It also has inbuilt frost protection for marginal frost areas.

Freezing and hard water protection
Although Chromagen open loop systems have inbuilt freeze protection for marginal frost areas, in locations where severe frosts or snow can occur, or where hard water supplies are prevalent, a Chromagen closed loop model should be installed.  In this unique design, the solar collector panels are connected to a highly efficient heat exchanger inside the storage tank.  The closed loop is filled with a special heat transfer fluid that won’t freeze and only the highly durable tank is exposed to the hard water supply.

Apartment houses
Chromagen has developed a unique solution for apartment houses to ensure hot water around the clock. Each apartment has an individual tank with all the tanks connected to a central collector cluster. A pump ensures continuous water circulation of hot water to each apartment.
