The National Trust is proud to announce the completion of the largest marine source heat pump in the UK as part of its Renewable Energy Investment Programme. The new system, which extracts heat from seawater, is now meeting all the heating needs of 300-year-old Plas Newydd mansion house in north Wales. The house was formerly the Trust’s biggest oil consumer, using 1,500 litres on some winter’s days. That’s the same as a typical house would use in ten months. Now it’s being heated by a renewable system that makes use of the beautiful Menai Strait, which is right on the property’s doorstep.
