Devon & Cornwall Solar Thermal Installers

Optiheat Renewables are MCS accredited installers of solar thermal systems for homes in Devon and Cornwall.

How does Solar thermal work?

Solar thermal is essentially the harnessing of the sun's free solar energy to heat cold mains water which has been pumped into your solar thermal panels positioned on your roof. The hot water that is generated can be used for your domestic hot water supply, under floor heating and central heating throughout your home.

The solar thermal system works simply by pumping cold water into the pipes within your solar thermal panels, which are fitted on your roof. The sun then heats up the cold water within the pipes. The now hot water is pumped into your hot water cylinder where it is stored until needed. This hot water can be used straight away, if the temperature is correct, or heated further by a boiler or immersion heater to bring the temperature up to the temperature on the thermostat.

Solar thermal heating systems work most efficiently in the summer, where you can get up to 100% of the hot water you use being provided by your solar thermal system. However, in the winter months where there is less sun, the solar thermal system often needs to be backed up by a boiler or immersion heater to ensure a hot water supply. Despite the system being less efficient in the winter months, you will still save money all year round. 

Solar Thermal Funding & Incentives

There has never been a better time to install a solar thermal system at your Devon or Cornwall home due to the government incentives and funding available, such as, the Renewable Heat Incentive and the Renewable Heat Premium Payment
