I would be really grateful to hear of people's experiences and advice with regard to heating a house the most effective way in France. We have bought a house in Haute Vienne to retire to shortly - it is in good working order and with few major alterations needed. However it will, next winter, when we are permanently resident, need some major work done on it to keep us warm! It has previously only been a second home/summer residence. First step, we realise, is to insulate the loft, as this has not been done. The house has two wood burners but burning these day in day out would not seem a good way to go and background heat for bedrooms/kitchen etc is needed. We are not sure of the best way forward and what system to purchase. Any recommendations would be appreciated, obviously bearing in mind that running costs is a factor. I understand Economy 7 as such does not work the way it does in UK; we have been advised to use "Air to Air" heating and also advised that "des chauffages à fluides calorifiques" would be a good way forward - the actual meaning/translation of which I am not sure!
Any advice or tales of previous experiences (good or otherwise) would be really very much appreciated.
