Think about the number of organisations that use large quantities of hot water – sports centres, schools, hospitals and many industrial processes. By investing in Solar Thermal energy, you can qualify for payments under the Renewable Heat Incentive (RHI) to offset the cost of your gas or electricity bills. Solar Thermal offers a Return On Investment (ROI) of seven to eight per cent, giving a payback period of less than 20 years.

The expected output of the system is 3,050kW a year, which will offset the gas needed to generate this energy.

About solar thermal


Like Solar PV, this technology harnesses the power of free sunlight and the technology is cost-efficient to install. Pure Renewables has its own team of experts with lots of experience of installing Solar Thermal systems. Heating technology is complicated and the systems need to be very well designed to deliver the optimum efficiencies and ensure they are safe. Solar Thermal systems can potentially operate at very high temperatures, therefore, health and safety is a critical consideration.




Solar Thermal works even in cloudy weather and requires very little maintenance. If the ambient sunlight isn’t enough to heat all the hot water, a backup boiler or heat-pump would provide the additional heat. Systems last for between 20 -25 years, depending on the quality of the system.


Service goes to the heart of our offering as a business. From our initial design and consultation to our award-winning installation and aftercare, we focus on delivering a quality solution on time and budget.


Our legacy in renewables means our projects are efficiently designed and run. We deliver expert installations based on many years of experience. This experience means we can offer clients technically superior solutions that enhance the benefits of renewables.


All of our renewable energy services are focused on results and meeting the best possible heating requirements. Our knowledge of the full spectrum of solutions means we can deliver the best possible renewable energy outcome.

Solar Thermal FAQs


How do Solar Thermal heating systems work?

Solar Thermal heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water that is stored in a hot water cylinder.


Is my property suitable?

Solar thermal systems can be adapted to almost any premises. The panels don’t have to be mounted on a roof. They can be fixed to a frame on a flat roof or hanging from a wall. The solar panels need to face south, south-east or south-west and be in direct sunlight for most of the day, so you have to be careful about obstructions such as trees and tall buildings.


What incentives are available for solar thermal heating systems?

The Renewable Heat Incentive is a payment for generating heat from renewable sources. Tariffs started in November 2011 for non-residential systems and April 2014 for households.


Is solar thermal expensive to maintain?

Solar thermal systems require very little maintenance. We recommend that the system is visually inspected annually and the system’s heat transfer fluid (glycol) is professionally inspected at least every couple of years for domestic but more regularly for commercial installations. We have a number of service options that we can talk you through.


Will I need planning permission?

Most solar water heating systems do not require planning permission. It’s always advisable to check with the local planning officer. New legislation such as the “permitted development” ruling means applying for planning permission, if it is required, should be a fast and efficient process.


What is the Renewable Heat Incentive?

The Renewable Heat Incentive (RHI) is a Government incentive scheme to encourage the uptake of renewable heat technology among businesses and homeowners. It covers a range of technologies, including ground to water heat pumps, air to water heat pumps and solar thermal panels. Air to air heat pumps, are not supported by RHI. The Non-domestic RHI was launched first in November 2011 to provide payments to industry, businesses and public sector organisations.


What could I earn?

RHI cash payments are made quarterly over seven years. The amount you receive will depend on a number of factors – including the technology you install and the latest tariffs available for each technology.


All renewable energy systems need to be designed so they are specifically tailored to the premises. This is essential to ensure you qualify for the Government renewable energy incentives such as the Feed-in-Tariff and the Renewable Heat Incentive.  We look at all aspects of your building so we can advise on how it can be made more energy-efficient and recommend the type of technology that suits you or your business. 

Green Homes Grant and Domestic RHI

The latest press release from the Government has confirmed that recipients of the Green Homes Grant will still be able to apply for Domestic RHI payments.   The scheme will see the Government fund up to two-thirds of the cost of home improvements, up to £5000. Low-income households will be able to receive vouchers covering […]

Our MD, Chris Whitelock, also delivered a masterclass seminar on the Sunday morning about, of course, heat […]

UK government to commit to 2050 climate target

Greenhouse gas emissions in the UK will be cut to almost zero by 2050, under the terms of a new government plan to tackle climate change.   The Prime Minister says that Britain has a “moral duty” to cut emissions. This will need a massive investment in clean energy generation including Ground Source Heat Pumps, […]
