Solar Thermal

A General Explanation:

This is a system where an absorber plate or panel of tubes is fitted in the roof and absorbs the heat from the sun to produce hot water and heat for your home.

How It Works:

When the sun is shining the solar panel collects U.V. energy and it's pumped through a heat exchanger warming the water stored in the hot water cylinder. This water can be used for washing and bathing, and is backed up with additional systems.

During the day (during the summer) the water in the cylinder may reach between 20-120 c within a 1/2 a day. The insulated cylinder will keep it warm for the next day.

It can save up to 70% off your domestic hot water bill.
