How does a solar thermal system work?

Solar thermal panels take energy from the sun and use it to heat the water in a storage tank, providing your home with more sustainable hot water.

  • The solar panels on your roof use the energy they collect to heat a solar fluid called glycol.
  • The glycol – part of a closed circuit – is pumped through a heat exchanger in a hot water storage tank.
  • The heat exchanger heats up the mains-fed water in the storage tank, which is then sent to your taps and showers on demand.
  • If necessary, your existing boiler boosts the temperature of the hot water in the tank.

With the help of the government’s Renewable Heat Incentive (RHI), installing a solar thermal system to heat your water in a more carbon efficient way could earn you a tax-free, index-linked income that’s guaranteed for the next 7 years for homeowners and 20 years for businesses.
