Powering a mansion with the sea

How do you turn water into power?
With the UK’s biggest sea source heat pump at Plas Newydd.

As anyone who lives in an old house will tell you, keeping the heating on takes a lot of fuel. That’s why, as part of our commitment to renewable energy, the National Trust is building the UK’s largest marine source heat pump to keep one of our Welsh mansions warm.
