Solar Thermal

Solar water heaters provide hot water for all sizes of project. This is a proven, mature technology suitable for a wide range of needs.

For domestic hot water there are three main components:

Solar panels or collectors - are fitted to your roof. They collect heat from the sun's radiation. There are 2 main types of collector:
- Flat plate systems - which are comprised of an absorber plate with a transparent cover to collect the sun's heat
- Evacuated tube systems - which are comprised of a row of glass tubes that each contain an absorber plate feeding into a manifold which transports the heated fluid.
A heat transfer system - uses the collected heat to heat water
Hot water cylinder - stores the hot water that is heated during the day and supplies it for use later.

The benefits

Solar water heating can provide almost all of your hot water during the summer months and about a third year round. The average domestic system reduces C02 by around 350 - 400kg per year, depending on the fuel replaced. This could save you around £50 a year.

Is it suitable for my building?

Solar water heating can be used in the home or for larger applications, such as swimming pools. You will need 3-4 square metres of southeast to southwest facing roof receiving direct sunlight for the main part of the day for a domestic system. You'll also need space to locate an additional water cylinder if required.

Choosing a system suitable to your needs requires consideration of a range of factors, including the area of south facing roof, the existing water heating system (e.g. some combi boilers aren't suitable) and your budget. A competent accredited installer will be able to assess your situation and discuss with you the best configuration to meet your needs.
