Plas Newydd to be heated by sea energy

Plas Newydd

A National Trust pilot project is to use sea water to heat one of the finest mansions in Wales.


Plas Newydd in Anglesey will use a 300 kw marine source pump to amplify heat from the sea . The development is expected to save around £40,000 a year in operating costs. The money will be reinvested into the conservation of the house.

Plas Newydd is not on the main gas grid, and until now it has been heated entirely by an oil-fired boiler.

The National Trust’s Adam Ellis-Jones voiced his excitement at the innovative project.

"With the Irish Sea right on the doorstep, a marine source heat pump is the best option for us," he said.

"Being a pioneer is never easy. There are very few marine source heat pumps and none of this size in the UK, so it has been a challenging project - but a very exciting one."
