» Solar Thermal Systems

Solar thermal heating systems, more commonly known as Solar Thermal, make use of a solar collector to absorb heat from the suns radiation to warm water which is stored in a water cylinder. This hot water can then be used for showers, baths and other domestic use.

In the UK, Solar Thermal systems typically make use of an anti-freeze liquid (Glycol) which acts as the Heat Exchanger. It absorbs the heat from the solar collectors and carries it to a second coil in the water cylinder. The first coil remains connected to the boiler for back up hot water heating when there is insufficient solar energy in the winter months.

Solar collectors are usually Flat Plate panels or Tubes that are attached to your roof or any other suitable location.

The solar Thermal system does not need direct sunlight to work and will still generate hot water on cloudy and overcast days

  • A Solar thermal system will typically provide between 60%-70% of a households annual hot water demands, with 100% of this demand being met in the summer months.
  • Solar Thermal collectors come in a range of different shapes and sizes, from some that look like loft windows, to tubes that can be angled to optimise the capture of the suns radiation.
  • Solar Thermal systems are not affected by the cold because they make use of an anti-freeze mixture called Glycol.
