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