Solar Thermal

What is solar thermal energy? Solar thermal systems provide hot water for domestic or commercial properties by using roof-mounted panels to collect the sun’s rays. Water can either be heated directly or indirectly. With direct systems the water that flows through the panels is the same that is used by the end user. With indirect systems the fluid heated by the sun is retained in a sealed circuit and heats the water used by the end user via a heat exchanger. This kind of system tends to be used in colder climates where there is a risk of freezing.

Most suited to business premises where most hot water is consumed during daylight hours, supplementary heating in domestic properties, and for indoor swimming pools that are used most intensively during the summer months.

How you benefit

Determining if solar thermal is right for you depends on the use of the property, as much as the other factors. Our specialists can give you independent advice without trying to sell you a product. Solar thermal panels can be particularly noticeable, and our expertise in dealing with historic and high value properties enables us to guid you on positioning the equipment to limit any adverse aesthetic impact, and gaining the all important Listed Building Consent, if this is needed.

  • Solar heat is free except for the energy required to pump water around the circuit.
  • Panels can be easily roof mounted.
  • Direct systems can be used in combination with existing hot water tanks.


  • The hot water produced by a solar thermal system in the UK will generally only be used to provide water for showers and hot taps, not central heating systems.
  • Systems will only supply a proportion of the hot water required, especially in winter.
  • Some traditional properties such as cottages with thatched roofs will not be suitable.
  • Planning consent may be required for listed buildings.
