Energy from the sun can be used in many ways. The main consideration here is its use in a domestic heating and hot water environment within the UK.

The Compound Parabolic Concentrator vacuum tube collectors capture and absorb the sun’s radiation.The heat from the tubes is then conducted to the fluid flowing through them.

The hot fluid from the collector is circulated via flexible tubes by a pump through to a copper coil inside the insulated tank.

The coil conducts the heat and the resulting hot water flows from the outlet valve.

The hot water is delivered to wherever it is needed throughout the house.


According to the National Renewable Energy Laboratory (NREL), A solar water heater is a long-term investment that will save you money and energy for many years. Like other renewable energy systems, solar water heaters minimize the environmental effects of enjoying a comfortable, modern lifestyle. In addition, they provide insurance against energy price increases, help reduce our dependence on foreign oil, and are investments in everyone’s future.

Solar water heaters, sometimes called solar domestic hot water systems, may be a good investment for you and your family. Solar water heaters are cost competitive in many applications when you account for the total energy costs over the life of the system. Although the initial cost of solar water heaters is higher than that of conventional water heaters, the fuel (sunshine) is free. Plus, they are environmentally friendly.
