How Do Solar Hot Water Heating Systems Work? - Evergreen

Solar water heating systems work by capturing sunlight and using it to provide a significant proportion of your annual hot water demands. Similar to the heat pump's method of capturing naturally-occurring energy, solar water heating systems do this by circulating a heat transfer liquid between the solar collectors on your roof and the twin-coil hot water cylinder inside your home.

Solar hot-water systems are also fairly easy to retrofit in existing homes. The solar-heated storage tank is simply linked to the existing hot-water tank, which switches on only when water from the collector falls below the water heater's temperature setting. In new homes, a single tank can be heated by both solar collectors and gas or electricity.

Solar heating systems: Are they a good idea?

Solar heating systems are nothing new: we humans have been applying the concept for millenia.
