Domestic solar thermal systems can produce 50%-60% of your total hot water requirements

A domestic solar thermal system uses solar panels to heat water rather than generate electricity like solar PV. The hot water is stored for use later in a cylinder and can easily provide a large proportion of a home’s hot water usage directly from solar energy. See how it works for a more detailed explanation.

By using the unlimited resource that the sun provides, installing a solar hot water system in your house could reduce your annual bills by 10% or more. As well as allowing you to benefit financially from the government funded Renewable Heat Incentive (RHI). Heating hot water makes up around 15%-20% of a households energy bill and this can be more if water is heated using electricity.

The Benefits of Solar Thermal

  • Free hot water – Solar thermal works all year round, though you will need to heat the water further with a boiler or immersion heater during the winter months.

  • Reduced energy bills – Sunlight is free, so once you’ve paid for the initial installation your hot water costs will be reduced and you will be protected against future price rises.

  • Lower your carbon footprint – Solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.

  • Eligible for RHI –  Receive government backed Renewable Heat Incentive (RHI) payments for every unit of heat you generate.


Maintenance costs for solar thermal systems are generally very low. Once fitted Caplor will leave written details of any maintenance checks that you can carry out from time to time to ensure everything is working properly.

For peace of mind we are able to offer an annual service check and it will be necessary to have your system checked more thoroughly every 3 years. It is likely that after this period of time, the anti-freeze that is used to protect your s
ystem in the winter months will need to topped up or be replaced.
