5 Bed house 216 sq metres with 3 showers and a bathroom. Built and extended over the last 200 years with a variety of insulation from the very latest, highest standards down to old non insulated parts of the house.
A Sanyo CO2 air source heat pump feeding a thermal store with instantaneous non stored hot water was fitted in March 2009 as the main source of heating and domestic hot water. This is backed up by the existing Calor gas system for very cold spells if necessary. The Calor system has been retained to run the Aga for cooking.
"I have been delighted with the constant supply of hot water, particularly with grand children and guests staying with us throughout the year. The system managed to cope with our mixture of under floor heating and radiators to give us a very comfortable background heat. We have noticed a significant saving in running costs"
