Photovoltaic Solar Water Heating (GreenHeat)

Save up to 80% of your water heating costs (30%-60% of your annual electric energy usage) without electric pumps and extensive pipework. This system connects to a standard hot water cylinder (existing or new) and is about half of the cost of other Solar Water Heating systems on the market.

PV (photovoltaic) Solar panels convert sunshine (even on cloudy days) directly into electricity. With GreenHeat controllers connected to the specially designed element, this system can be connected into your existing Hot Water Cylinder and will heat the water even during a power cut. With a ‘payback’ (cost vs savings) of around 4-5 years for an average family home the math is easy and future gains are large.

With a much longer life expectancy then heat pump technology and greater power saving potential this is the way of the future. The systems dual AC/DC Stainless steel element is expected to outlast any new hot water cylinder and even if it needs replacing the cost is minimal compared to heat pump system repairs that are often in the thousands and not even worth repairing. The PV panels on the roof have a 25 year warranty and the system is completely transferable to any replacement cylinder. Use your hot water cylinder as free solar battery today!

​Advanced Technology:

Heating elements made with PTC chips do not use resistance wire as a source of heat. Instead, they use a number of ceramic PTC chips as the heating source. PTC  heating elements are ceramic chips that have self-limiting temperature characteristics. As the PTC chips heat up they reach a designed temperature at which the heat output decreases drastically and stops it from getting hotter. As ambient temperature increases and less heat is dissipated, the resistance of the element will increase resulting in a near zero current draw at its designated temperature.
