- Building constructed in 1982 - 50-100mm cavity wall insulation (not currently known) - so faily low by modern building regs. Masonry constrction (300mm wall thickness) - 22m2 ground floor, 22m2 first floor - Currently use a lot of energy as it is electric only. This may be partly due to the economy 7 tarrif we are on an using 70-80% of energy outside of the economy 7 hours. - The house is not currently draughty as still relatively modern construction, but I agree to improve effectiveness would likely require additional external wall insulation + render or dry lining. There is currentl;y minimal loft insualtion.

Hi all, Does anyone have any experience of installing underfloor heating in an existing building relying on an air source heat pump? I would be grateful if someone could give me an idication of the installation costs and reliability? I am looking to fully refurbish and extend my one bedroom end of terrace house and install an air source heat pump on an south-west facing external wall at first floor level. Thanks!
