Stiebel Eltron Project Named “Outstanding” At Wales Green Energy Awards

An innovative scheme involving the installation of the UK’s largest ever marine source heat pump has won the “Outstanding Project” at this year’s Wales Green Energy Awards.

Judges praised the “unique” nature of the project by National Trust Wales to install the heat pump at Plas Newydd in Anglesey.

The 300kW pump at the National Trust’s Plas Newydd mansion in Anglesey utilises the tidal currents of the Menai Strait to provide all the power needed to heat the property.

The marine source heat pump was manufactured by renewable energy manufacturer Stiebel Eltron UK and installed by Kimpton Energy Services, both of whom are headquartered in Bromborough, Wirral.

Plas Newydd, built in the 18th Century, was formerly the National Trust’s biggest oil consumer – using up to 138,000 litres of oil annually at a cost of around £70,000.

In May, the Trust unveiled the ground-breaking project, the first of five schemes to be completed in a £3.5million pilot phase of its Renewable Energy Investment Programme.

Yesterday’s success is the latest triumph for Stiebel Eltron UK, which earlier this month won Commercial Project of the Year in the Energy Efficiency and Renewables Awards for its work at Plas Newydd and last week also captured the Low Carbon Award at the Wirral Business Awards for the same scheme.

The Plas Newydd marine source heat pump pumps a small amount of sea water from the Menai Strait through a network of pipes to and from a heat exchanger on the shore, and then up 30 metres of cliff face to the mansion’s boiler house.

Mark McManus, Managing Director of Stiebel Eltron UK, said: “It is fantastic for everyone involved in the Plas Newydd project to win such as prestigious honour in the Wales Green Energy Awards. This latest success caps a remarkable month for Stiebel Eltron UK and our partners on the National Trust project.

“The installation of the pump is transforming energy usage at Plas Newydd, dramatically improving its CO2 performance and saving tens of thousands of pounds a year that were previously being spent on oil.”

The project is able to take advantage of the Government’s Renewable Heat Incentive (RHI) which should mean that the National Trust’s investment will be paid back within seven years.

Richard Kimpton, Managing Director of Kimpton Energy Services, said: “Plas Newydd was an innovative and challenging project for everyone involved and I am delighted that it has been recognised with such a prestigious award.”

A team of more than 40 people were involved in the installation of the marine source heat pump at Plas Newydd which forms part of the National Trust’s Grow Your Own Energy programme. Targets include reducing energy usage by 20 per cent and meeting half of its energy requirements through renewable energy.

The project saw a number of firsts – the first marine source heat pump of its type in the UK, the biggest at 300kW and the first in open sea rather than a harbour.

Other key partners in the project included SEACAMS, led by the School of Ocean Sciences at Bangor University, and 100 per cent renewable electricity supplier Good Energy which launched the Renewable Energy Investment Programme with the National Trust last year.

The Wales Green Energy Awards were presented at a special ceremony at the St David’s Hotel and Spa in Cardiff Bay.
