Are you considering installing a solar water heating system in your New Zealand home or business? This guide, curated by the Green Heat team, is full of everything you need to know about solar water heaters, including how to operate and maintain them.
What is a PV Solar Water Heater?
PV solar water heating uses photovoltaic technology and a unique PTC AC/DC element to heat the water in the hot water cylinder (HWC). This differs from traditional thermal hot water systems where water is cycled from a collector through pipes to the HWC, either making use of a 220V Pump, 12V Pump or natural convection.
The PV solar method of water heating is considered highly efficient and environmentally friendly as it reduces the dependency on traditional sources of energy, such as gas or electricity.
