Geyserwise 150L PV Solar Water Heating System
Advantages over thermal hot water systems are as follows
• Any existing geyser can be converted.
• No Additional plumbing is required.
• No pumps necessary to circulate water.
• No risk of damaged panels in frost prone areas.
• The water temperature can be controlled on very hot summer days – reduced risk of overheating in problems.
• Suitable in all water conditions.
• Suitable in areas where the geyser is not situated near the panels.

Geyserwise TSE Geyser Controller
Below you can find more information on a revolutionary product that will drastically reduce your electricity expenditure, while lowering your carbon footprint.
With our intelligent energy control unit you can :
– Digitally program, monitor and control your geyser’s energy consumption.
– Save up to 20% on your electricity bill.
– Protect your geyser from malfunctions, scale build up and element failure.
GeyserWise units were designed and patented in South Africa and work on traditional geysers and most solar powered geysers are SABS approved.
PTC Element 2.2kW AC, 900W DC (Please Specify Screw boss and Fl**ge mount)
The dynamic resistance and output of PTC heaters makes them an excellent choice for providing controlled electric heating. In many applications it is possible to do away entirely with thermostatic controls. Simplification of design and reduced energy consumption represent significant cost savings for a given application. The removal of failure prone components such as thermostats can also add significantly to the reliability of a product. Safety is an added benefit, since no matter how much current is applied to the PTC; it will never surpass its intended surface temperature.
