National Trust fits ‘pioneering’ ground source heat pump at Kingston Lacy | Renewable energy

Kingston Lacey was built to resemble a Venetian palace realized in the English countryside, and over the years has been kept warm and dry by open fires and coal and oil boilers.

A 'pioneering' ground source heat pump has been installed to protect this spectacular natural beauty. Country mansion in Dorset There is also a collection of paintings by masters such as Velázquez, Titian and Rubens.

The new system will help preserve art collections by providing stable, gentle heat with no temperature spikes or dips, saving 30,000 liters of oil each year.

This is one of the National Trust's largest heat pump projects to date and is the charity's first installed high temperature ground source system.

Old oil tanks have been replaced with approximately 6,000 meters (19,685 feet) of underground pipes that carry natural ambient heat from the ground to four high-temperature heat pumps that heat the 17th-century mansion and courtyard buildings.

To install the piping, 32 vertical boreholes were drilled in the overflow parking lot, each 180 meters deep.

Experts spent two years carrying out extensive archaeological and ecological research to ensure the protection of the historic parkland, which includes Iron Age hillforts, heathland and water meadows.

The new heating system not only saves around 57 tonnes of carbon per year, but also eliminates the risk of oil spills from the previous boiler and storage tank.

The trust also says the heat pump will improve the preservation of the building and its collection by stabilizing temperature and humidity levels.

Known as the “Palace of Art,” the house includes a luxurious Spanish Room and a lavish Spanish Room designed by William John Banks, who founded the house in the 19th century, from exile after being exiled from England for having a homosexual relationship with a soldier.

Owen Griffiths, National Trust Renewable Heat Project Lead Manager, said: “Even in the most historically significant environments, like Kingston Lacey, it is possible to integrate these cutting-edge technologies.

“Heat pumps not only reduce the facility's dependence on fossil fuels, but also create a safer environment and improve conditions for our collections here.

“While these grand buildings have been around for centuries, their heating systems have evolved from open fires to coal boilers to oil boilers, with many energy innovations along the way. This is simply the next step in the history and preservation of Kingston Lacey.”

Mr Griffiths added: “What we've found in moving from fossil fuel-saving heating to heat pump-saving heating is that extending the heating time means that lower-grade heat has more time to enter the building, so the heating time is reduced. This means that it will be longer and more gentle. Since the internal environment can be stabilized for a long period of time, fluctuations between day and night can be balanced.

“There's no rapid heat generation like you get from fossil fuels. This means there's a more stable environment that reduces the chance of mold growth and insect infestation.”
