Distributors and installers of solar hot water heat pump systems. Save electricity by installing an affordable high quality heat pump system to your existing geyser. Eskom approved suppliers.A Heat Pump collects “free energy” just like a solar water heater. A Heat Pump works by transferring heat – not by converting electrical energy in to heat. It removes the renewable energy from the warm air in the environment that has been heated by the sun for free. This energy is converted and used to super heat your water which is then stored in an insulated storage vessel (your geyser tank). A small amount of electricity is required to operate the compressor.
