Water source heat pump saves National Trust £23,000 19 July 2012

Midlands based Lorien Engineering Solutions has helped the National Trust's Packwood House, in Warwickshire, to drive down yearly operating costs by £23,000.

Its pioneering water source heat pump system is one of the first installed at a National Trust property and was completed over the winter with 5,000 metres of pipe submerged in the lake in a series of coils.

The heat pump works by circulating a food-safe glycol fluid through the pipes, which absorbs solar energy in the water.

A team of sustainability engineers at Burton-based Lorien designed and managed the installation, completing the project in 90 days with finance from a £192,500 grant from energy provider npower.

Lorien's Stuart Perry says that the installation's constant cycling of fluid through the coils is virtually silent and although the process requires an electrical demand to run, will produce "up to four times as much energy as it needs to run".

A 250 metre trench was dug to connect the pipes to the new heat pump units by the house, replacing existing oil-fired boilers.

"The water source heat pump is a really great addition to the property," comments Packwood's house manager Joy Tovey.

"It provides us with a constant source of steady heating, which, for older types of our properties such as Packwood House, are essential," he continues.

"Over time it will save us a lot of money, allowing us to invest in essential property maintenance and the conservation of our chattels for us and future generations to enjoy."
