Solar Water Heating

Solar water heating can lower energy bills, is good for the environment and can add value to your home.

Solar water heating (SWH) or solar hot water (SHW) systems comprise several innovations and many mature renewable energy technologies that have been well established for many years. SWH has been widely used in Greece, Turkey, Israel, Australia, Japan, Austria and China.

In a "close-coupled" SWH system the storage tank is horizontally mounted immediately above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermosiphon flow. In a "pump-circulated" system the storage tank is ground or floor mounted and is below the level of the collectors; a circulating pump moves water or heat transfer fluid between the tank and the collectors.

SWH systems are designed to deliver hot water for most of the year. However, in winter there sometimes may not be sufficient solar heat gain to deliver sufficient hot water. In this case a gas or electric booster is normally used to heat the water.

Our Solar Water Heating Projects

11 Fernwood Somerset West | water 11 Fernwood Somerset West

The project is a new development where GGHS installed 2x 200l evacuated tube systems. The client wanted to have a development move more off grid before the actual completion of the project. The 2x...


11 Fernwood Somerset West received a rebate of R10 444 in total through the Eskom initiative.
Citrusdal | water Citrusdal

The Citrusdal project was a rooftop installation that allowed the client to save considerably on their monthly electricity bill. The project was completed within 2 days.
