Solar Thermal Water Heating - Direct Heat From The Sun

Many people think that solar panels only work in the summer.
Not so… this type of free energy is available throughout the year. From May to September, thermal Solar can produce up to 100% of the energy required for heating your domestic water, operating not only with direct sunlight, but also diffused sunlight. They even work on cloudy days!

Benefits of Solar Energy

A solar thermal system can provide most of your hot water needs during the summer months, or approximately 60% of your hot water needs throughout the year (figures depend on geographic position).

Renewable Heat Premium Payment?

The RHIwill pay a fixed amount per year to those who opt to change from heating systems operated by fossil fuels to renewable options The RHIpays participants of the scheme that generate and use renewable energy to heat their buildings. By increasing the generation of heat from renewable energy sources (instead of fossil fuels), the RHIhelps the UK reduce greenhouse gas emissions and meet targets for reducing the effects of climate change.

There are two parts to the RHI:

  • Domestic RHI– launched 9 April 2014and open to homeowners, private landlords, social landlords and self-builders
  • Non-domestic RHI– launched in November 2011 to provide payments to industry, businesses and public sector organisations

How will it work?

The payments made will either be made on the exact amount of heat produced or on the amount it is anticipated the installation will provide. The former means you’ll need to have a meter fitted to your system, in the same way as gas and electricity is metered, to account for the heat produced while the latter is paid on an estimate.

And unlike the Feed-in Tariffs which limits payments to installations with a maximum of 5MW, the RHI will apply to heat installations of any size.

The Government has confirmed that payments will be made on a quarterly basis over seven years. The following tariff rates for the domestic RHIapply:                                                                                                    

Solar thermal panels (flat plate and evacuated tube)


Ground source heat pumps


Biomass boilers and biomass pellet stoves with a back boiler


Air source heat pumps (air-to-water)


Households with biomass boilers and heat pumps who install a metering and monitoring package will also receive additional payments per annum of £200 and £230 respectively.

To be eligible for RHI payments you will be required to have a Green Deal assessment and where appropriate have cavity wall insulation and a loft insulated to a minimum of 250mm. If you have a biomass system the installation will need to adhere to fuel sustainability and air quality requirements.
