Packington Hall is a magnificent building standing in 300 acres of parkland. The hall is not open to the public, it is privately owned by Lord Aylesford and has been in the family since 1560.
The owners approached Ecovision having heard about the success of the installation at Castle Howard using the lake and hoped that something similar may be possible at Packington. His target was to reduce the cost of heating the main building whilst protecting the long term sustainability of his home for future generations.
Ecovision designed a system that will heat the main house comfortably using the lake as the heat source. The house had a radiator system that was suitable for a heat pump, large cast iron radiators have a large surface area and emit heat at a lower temperature well in an older building, emulating the effect of open fires which they would have had in former times.
There are 2 x 100kW heat pumps in the plant room with a 150m trench leading from the main house basement to the manifold chamber on the lakeside. The heat pumps heat the main house and supply 1,000 litres of hot water requirement throughout the winter months, switching to heating the swimming pool during the summer. The pool will be kept at 28/30 degrees from May until October. By using the lake it will be possible to use the heat pumps all year round without the problem of needing the summer re-charge.
The collector coils were placed in the lake, in an area connecting the great pool and the hall pool where there is a movement in the water allowing the cooler water to be replenished.
The heat pumps replace an oil system that was using 48,000 litres of oil at an estimated cost of 0.60p per litre. The oil boilers were left in place as a back-up to the heat pumps should they ever be required, providing an automatic bi-valent system controlled by the heat pumps.
It is imperative that the loops are designed and installed correctly to ensure the success of the installation.
This beautiful home will now remain immune to any increases in the cost of fossil fuels for future generations.
