Thermosyphon
Solar Water Heating System – Option 1
Imported, closed/indirect thermosyphon system, designed in Germany. A closed/indirect system is one where the household water remains in the tank, and an anti-freeze solution is used in the collectors, which heats the household water. The two liquids never mix. Should the water temperature drop below a certain setting, the system will automatically switch over to electricity to increase the temperature to the desired setting. This system can save up to 80% of water heating costs. This system carries the SABS mark of approval, and qualifies for an Eskom rebate of R 5 615 which will be paid to you the customer. The system comprises a 180 litre tank (3-4 people) which must be mounted above the collector. The collector is covered by 4 mm toughened glass. This system can be mounted either on a pitched or flat roof.
