Ground source heat pump to be installed at National Trust's Kingston Lacy that will 'help preserve the estate's art collections'

The National Trust has announced plans to install a ground source heat pump at Kingston Lacy in Wimborne, Dorset.

The new heating system will require 32 boreholes at a depth of 180 metres and will supposedly save 57 tonnes of carbon emissions a year by replacing the home's use of open fires and oil boilers.

As well as this, it is claimed by the National Trust that the ground source heat pump will help preserve the estate's world renowned art collections by helping to maintain "stable environment" for the paintings and artefacts.

Kingston Lacy dates back to the 17th century

Kingston Lacy is a 17th-century country house and estate near Wimborne Minster in Dorset that houses a variety of paintings by artists such as Velázquez, Titian and Rubens.

It is known for its lavish Italian-inspired architecture, extensive gardens, and rich history and was been owned for centuries by the Bankes family, who were close allies of Charles II and other royals.

Kingston Lacy is now managed by the National Trust, a charitable organisation dedicated to preserving and opening heritage sites.

6,000 metres of underground pipes laid

This National Trust initiative stands as one of their most extensive heat pump projects and marks the introduction of a high-temperature ground source system.

The replacement of the old oil tank at the Dorset country mansion includes an intricate network of underground pipes, spanning 6,000 metres, harnessing natural ambient heat to fuel four high-temperature heat pumps.

The installation of the ground source heat pump involved drilling 32 vertical boreholes, each reaching a depth of 180 meters, located in an overflow car park.

GSHP will help preserve the historic art collections

As well as saving approximately 57 tonnes of carbon a year, the new heating system will help preserve the art collection in the home by maintaining a steady temperature.

Owen Griffith, the renewable heat project manager for the National Trust, said: “Not only will the heat pump reduce the property’s dependency on fossil fuels, but it’ll create a safer environment and improve conditions for the collection items here.

“Magnificent buildings like these have been around for centuries, but their heating systems have evolved – from open fires to coal boilers and then oil boilers, with many energy innovations along the way.

“What we’ve found when we’ve moved from fossil fuel conservation heating to heat pump conservation heating is that extending the heating time means that we have a longer duration of lower-grade heat coming into the building so it’s a lot gentler. We’re able to stabilise the internal environment over a longer period so daytime/night-time fluctuations, for example, are balanced out.

“You don’t get the spikes in heat from that you get from fossil fuels. It means we have a more stable environment that reduces the likelihood of mould growth and insect infestation.”
