The sun radiates an immense amount of energy to the Earth. If it could all be tapped, the amount of solar radiation that reaches the globe every half hour would be enough to meet worldwide energy consumption requirements for an entire year.

Solar heating flat plate collector panels heat water and save energy wastage. The collectors contain liquid that circulates through panels and is heated by sunlight; this then passes through a coil in the water tank which heats the water in the tank.

WHERE CAN THEY BE USED?

Although typically used domestically, there are solar thermal systems on the market to cater for any size of building. Ideally they will need to be mounted on a south facing surface, which receives direct sunlight for most of the day.

WHAT ARE THE BENEFITS?

  • Reduces CO2 emissions on an average domestic system by up to 400kg per year (depending on the fuel being replaced)
  • Easy-to-install and maintain
  • They can easily be integrated with other heating systems to meet the additional hot water requirements during winter.
  • Reduces hot water heating energy costs. Solar hot water can save money, reduce your carbon emissions, and can give you lower dependence on expensive imported energy.

There are a number of installation options available including surface-mounted options for pitch or flat roofs, A-frames, in-roof and complete roof installation, canopy or fafaçadeade construction. We can advise you on the best solution for your project.

Solar thermal systems need to be:

  • Connected to a twin coil cylinder, which is often bigger than a standard hot water cylinder. One coil receives heat from the solar collector on the roof, while the second receives heat from the other main heat source.
  • When there is insufficient sunlight we offer a full range of hot water cylinders and can advise you on the correct size of cylinder for your project. Space should be allowed for these cylinders when planning your project. You will need 2-4m2 of South-East to South-West facing roof space.
  • DIY jobs are not eligible for grant funding and the best practice is to use a professional installer.
