- Heating future secured as Marshland Primary Academy launches ground source heat pump system and other green energy upgrades
- Pupils and teachers are enjoying warm, comfortable classrooms while cutting carbon emissions by close to 80%
- Green upgrades include new radiators and is one of the first schools in the UK to use solar PVT ground source heat pumps, providing long-term energy savings
- Project provides a clear and scalable model for other schools to follow and is the latest to be delivered by leading ground source heat pump specialists, Kensa
Pupils and teachers at Marshland Primary Academy in Moorends, near Doncaster, part of Venn Academy Trust, are celebrating cutting their carbon footprint after successfully installing a modern ground source heat pump system and other state-of-the-art energy efficiency measures.
Working with Kensa, the UK’s leading manufacturer and installer of ground source heat pumps, the school is trailblazing how to go green, overhauling its old heating and hot water system and replacing the ageing gas boilers with seven new ground source heat pumps.
The six-month project, partially funded by the Government’s Condition Improvement Fund, also included fitting new radiators and 69 solar PVT panels, an emerging technology used in renewable heating installations. The upgrades are expected to boost the school’s energy efficiency, cut heating-related carbon emissions by close to 80%, and ensure classrooms stay warm and comfortable throughout the year for the benefit of staff and pupils alike.
The newly installed ground source heat pumps use renewable energy stored in the earth to provide heating and hot water and are hidden inside two converted plant rooms. To reach the underground energy, 18 boreholes were drilled beneath the school’s playing field, each to a depth of around 127m.
Solar PVT has been integrated into the school’s ground source heating system, taking it beyond a standard ground source heat pump installation. The technology generates both electricity and thermal energy, supercharging the heat pump’s efficiency and lowering installation and energy costs. This integration works by:
- Thermal heat energy captured by the PVT panels is removed and transferred to the heat pump system, improving its efficiency and reducing electricity use.
- Using this excess thermal energy in the heat pump system significantly reduces the number of boreholes needed, lowering the overall installation costs.
- Extracting the excess thermal heat from the panels increases the amount of electricity they can produce compared to ordinary solar PV panels. It's projected they will generate 34 kW of electricity—the output of 10 typical homes with solar panels.
- Marshland Primary Academy is one of the first UK schools to embrace this energy-saving technology alongside a heat pump installation.
Investing in energy efficiency upgrades has provided the school with a low-cost, low-maintenance, renewable heating system, securing its energy future while providing long-term savings on heating and hot water bills.
To meet the government’s goals of reducing public sector carbon emissions by 75% by 2037, thousands of schools across the UK will need to follow Marshland Primary’s example, replacing their ageing, high-carbon-emitting heating systems and embracing more innovative, modern technologies.

Penny Marshall, Acting Principal at Marshland Primary Academy , said:
It has been an exciting journey watching and learning about the innovative ground source heating. Although the children had to sacrifice their field for the summer, they enjoyed watching the holes being bored and learning from Kensa staff how the system worked.
Energy efficiency and helping the environment is a big focus at Marshland, so it is exciting to be able to know that we are playing a small part in a much bigger picture by using natural resources to heat our school. This winter has been a toasty one at Marshland!”
Wouter Thijssen, Commercial Director at Kensa, said:
We’re proud to have worked with Marshland Primary Academy to deliver a more sustainable and efficient heating system. Thanks to a mix of super-efficient ground source heat pumps and other energy efficiency upgrades, pupils and teachers will enjoy warm classrooms while slashing their carbon footprint.
By opting for ground source heat pumps, boosted by solar PVT, the school has secured its long-term energy future, setting the benchmark for achieving sustainability in UK schools. Kensa’s mission is to deliver better heating, and this installation certainly lives up to that promise.
