How do Solar Thermal Systems work?

Solar thermal systems comprise of a roof mounted collector (either 'flat plate' or 'evacuated tube'), a solar pump station, controller and a 'twin coil' hot water cylinder. The system utilises a heat transfer fluid, which collects heat from the solar panel on the roof, releasing the heat energy to a secondary 'coil' within a property's hot water cylinder to heat the stored water. 

The system has two thermistors to determine when heat energy is available in the panel to heat the hot water cylinder.

They work best on a southerly roof elevation, free from shading from adjacent properties or trees.

What is the Renewable Heat Incentive

The Renewable Heat Incentive (RHI) is a government incentive for encourage the investment in low carbon heating appliances in the home.

The scheme is administered through Ofgem, who provide tariff payments (paid quarterly over seven years) to 'bridge' the cost of low carbon heating systems over conventional fuel fired equipment (oil/gas boilers).

A four bedroom property can attract funding of up to £3,000 towards a solar thermal system from the RHI scheme, with a annual energy bill saving of £70-£100.

What do Griffiths offer?

Griffiths offer a no obligation survey and quotation; which a surveyor shall visit a property to determine the feasibility of installing a system. Provide a bespoke system design depending on the property and occupancy requirements, a full clear quotation which estimates the systems benefit to the customer including the amount of government funding the system may attract.

We aim to design the system to provide the maximum energy saving to the customer. This means generally the hot water cylinder is enlarged to allow the maximum amount of heat energy to be collected by the system.

What are the benefits of Solar Thermal Systems?

  • Free hot water from April - September 
  • Lower gas/oil/electricity bills
  • Funding from the governments RHI scheme
  • Improvements to a home's energy efficiency rating
  • Value to the property when selling.
