HOW DOES IT WORK
A heat pump is a highly efficient, cost effective method of heating water. It utilizes the sun’s free energy by extracting heat from the sun-warmed air and transferring it efficiently to the water. Because the heat pump moves the free heat from the outside air to the water, rather than create heat, as a fossil fuel or electric resistance heater does, it can heat your geyser water for up to 70% less cost than other less efficient methods. As the ambient temperatures changes, the heating output of a heat pump will vary. However, even when temperatures are cooler the heat pump continues to transfer heat between air and water. SIRAC heat pumps are designed to operate between -5°c and 40°c ambient temperature.
