Solar thermal technology

Renewable Heat Incentive

Solar thermal technology was given a major boost in July 2011 with the introduction of the Renewable Heat Incentive (RHI). The financial support available through the RHI has significantly shortened the payback times for these systems.

Solar thermal systems collect heat from the sun and use this to heat domestic hot water. Collectors are usually placed on the roof of the building close to the location of the hot water cylinder(s).

Design plans

Typically a well designed solar thermal system can produce more than 50% of the hot water required in each year. The need to effectively integrate solar thermal technology with the existing or planned heating infrastructure means that 'well designed' really is the key to a top performing system.

Redcotec approach

Solar thermal hot water system

In general, for commercial premises, hot water use is unlikely to be the dominant source of site carbon dioxide (CO2) emissions.

Therefore, solar thermal systems are frequency used in conjunction with other Low and Zero Carbon (LZC) technologies. Redcotec's expertise in determining load profiles and LZC strategies in general places us in an ideal position to calculate where solar thermal systems can contribute most effectively to your targets.

RHI Metering Reports

Redcotec is able to provide the Independent Report on Metering Arrangements (IRMA) that enables you to successfully claim the RHI for larger projects. We offer technical support and can prepare all the system drawings and other information required by Ofgem. Our aim is always to make the whole process as quick and simple as possible.

Renewable Heat Incentive (RHI)

  • Government scheme for renewable heat
  • Introduced July 2011
  • Similar to feed-in-tariff for electricity
  • Dramatically reduces running costs
  • Boosts financial returns

Key considerations

  • Available roof area
  • Hot water distribution system
  • Permitted roof loadings
  • Roof orientation and pitch
  • Hot water usage profile
  • Location of hot water cylinders
