Heat pumps reduce energy costs by nearly 90% for historic house in Yorkshire

A reduction of nearly 90% in energy consumption for an historic house in Yorkshire is achieved by these two 100 kW heat pumps from Dimplex.

Energy costs at Castle Howard, one of Britain’s finest historic houses, have been reduced by nearly 90% following the installation of two 100 kW Dimplex ground-source heat pumps to replace the previous heating and hot-water systems. Measurements over three months of operation since the heat pumps become operational in October saw average fuel bills fall from £4690 per month to £644.

The owner of Castle Howard, Simon Howard, says, ‘We’re delighted to see that our investment in the future and the installation of heat pumps is already paying off so positively. They have only been operating for a few months, and we’re really excited about the results so far as it ticks all the boxes for lower carbon, lower fuel bills, reliability and an expected life of 25-plus years.’

Dimplex installer partner Ecovision Systems devised the installation, which has a projected payback of just six years. The 6-month £200 000 project received a significant level of grant support from Dimplex via the Carbon Emissions Reduction Target Scheme, as well as an interest-free loan of nearly £60 000 from the Carbon Trust.

Heat is drawn from the 3-acre lake via coiled pipes and provides hot water and heating for the main house, the estate office and four staff flats.
