Solar Thermal – solar heating installers in Cornwall

What is solar thermal?

Solar thermal technology uses energy drawn from the sun’s light to generate low-cost, renewable energy to heat water in homes and businesses.
Similar to a solar photovoltaic system that also draws green energy from the sun, solar thermal technology primarily focuses on providing hot water.

How does it work?


A solar thermal system works by absorbing heat through solar panels, referred to as collectors, situated on or near to the desired building. The collectors use heat from the sun to heat up water which can then be stored, usually in a hot water cylinder, and used when required. A boiler or backup system can be used to further heat the water or if the hot water demand exceeds solar thermal production.

Why install solar thermal in your home or business?

Lowering the non-renewable energy required to heat the water and replacing it with free, renewable sunlight, solar thermal technology can provide several benefits to the owner.

Firstly, because of the lowered demand for fossil fuels to provide the energy to heat hot water, utility bills are lowered. It is estimated that solar thermal technology can reduce utility bills by anywhere up to 70 percent

Another main advantage of installing a renewable energy system, such as solar thermal, is a lowering of carbon emission and a reduced carbon footprint. This can be particularly useful to commercial building owners who need to meet government mandates to install renewable energy.
