Solar Thermal Water Heating Systems
Solar water heating systems can help you achieve savings on your energy bills. Based on the results of a recent field trial*, typical savings from a well-installed and properly used system are £60 per year when replacing gas heating and £70 per year when replacing an electric immersion heating.
Although the system works all year round, heating around 80-90% of your hot water in summer, a conventional boiler or immersion heater can be required to make the water hotter during the winter months.

energy consumption and cut costs.”
Reduced Carbon Footprint
A typical Solar water system will save 275kg of CO2 per year compared to water heated by gas and 490kg compared to water heated by electricity.
Earn As You Save
You may also be able to receive payments for the heat you generate from a solar water heating system through the government’s Renewable Heat Incentive:
2 person household = £190 RHI Income per year
3 person household = £260 RHI Income per year
4 person household = £330 RHI Income per year
5 person household = £425 RHI Income per year
6 person household = £460 RHI Income per year
How Does Solar Thermal Work?
Solar water heating systems, also called solar thermal systems, use the power of the sun to heat your home’s water.
Solar water heating systems use solar panels fitted to your roof to collect heat from the sun to heat up water stored in a hot water cylinder. This is done by passing a fluid through the panels and pipework, which heats up and is then pumped through a coil within your water cylinder, which heats water in the cylinder to the desired temperature
“Panels collect heat from the sun, which heats water in a cylinder.”
Solar heating systems tend to work much better in summer months, heating around 80 – 90% of your hot water, but can still provide significant benefits during winter months too. The solar fluid never touches the water itself, but merely heats the cylinder to the desired temperature through heat transfer.
