Solar Thermal Technology

Solar water heating systems use free heat from the sun to warm domestic hot water. A conventional boiler or immersion heater can be used to make the water hotter, or to provide hot water when solar energy is unavailable.

On average, every home spends 20-25% of its combined annual energy bills on water heating. In the UK a well designed solar water heating system can provide almost all the hot water for a home during the summer months and on average around 50-60% year round. This is why solar water heating systems are one of the most cost-effective and environmentally-friendly renewable energy solutions available, reducing fuel bills and building carbon dioxide emissions.

The Process:


  1. A heat transfer fluid is pumped into Solar thermal panels on your roof
  2. While passing through the panels the heat transfer fluid absorbs heat from the sun
  3. The heat transfer fluid carries thermal energy back to a heat exchanger where it is used to heat cold water from your water tank
  4. The Hot water is then pumped back into your water tank
  5. Any shortfall in hot water requirements will be made up by your home boiler
  6. Your Solar heated water can now be used in your home
