Heat pumps for historic manor house

We are proud to announce that we are the finalists in the renewable project of the year category for H&V awards.

Total NRG helped an Elizabethan country house called Soulton Hall in Shropshire to go green. Using two Sriebel Eltron ground source heat pumps, generating green hot water and heating for the 30- room manor house and coach house.

Having previously used oil and electricity, the luxury hotel and wedding venue is now saving more than £10,000 each year in fuel costs, as well as achieving a substantial reduction in CO2 emmissions.

“As there was plenty of ground space available, we decided to go with a twin ground source heat pump system, with a Stiebel Eltron WPF27HT heat pump working alongside a Stiebel Eltron WPF35 heat pump.

“The WPF27HT is providing heating and hot water, while the WPF35 is being used for heating only – with a total output of 62kW, we designed the system so that in the summer months only 27kW is needed, reducing energy usage and costs.

“The WPF27HT unit also pasteurises the 1,000-litre DHW cylinder instead of using an emersion element, which increases the overall efficiency of the system.

“We laid 3,800m of ground loop with a pre-assembled manifold chamber which is 90m away. The system looks great and the client is very happy with the design.”

Owned and managed by the Ashton family, Soulton Hall has invested heavily in green energy systems over the past two years and is firmly committed to sustainability.
More than 200 solar panels produce around 70,000kWh of free electricity for the home site each year – which in turn powers the ground source heat pump.

Tim Ashton said: “We are delighted that the heat pump system has been commissioned and is now up and running.

“We use our own green electricity to help power the heat pump, which is taking the constant 10°C temperature under one of our fields to meet all our hot water and heating demands.

“Ground source was always going to be a great option for us as we have plenty of space for collectors – the ground loops here are under an area of 3 acres. We were also able to easily convert the former log store into a plant room. Active consideration is now being given to two further schemes, aimed at balancing the electricity demand of our four holiday cottages.”

Stiebel Eltron is one of the world’s leading manufacturers of renewable technologies such as ground and air source heat pumps, solar PV and solar thermal.

Mark McManus, Stiebel Eltron UK managing director, said: “Historic sites such as Soulton Hall are traditionally very hard to heat with poor insulation – however with this project we have demonstrated that with the right technology and design, it is possible to retro-fit a green energy system that can optimise both cost and energy savings.

“Total NRG have done an excellent job with the installation and we are delighted that the system is now up and running.”
