Hi there Need some advice on our little house. A four bed bungalow which is five years old. All good except the builder had originally intended as a summer home and installed electric storage heaters in living space and removable convector heaters in bedrooms. We bought the house as a full time residence, needless to say we're hoping to upgrade the heating system. We are pretty clueless though, we're presuming oil as its in the country (no gas available). How much would such an upgrade cost?Should be consider sustainable energy solutions, as part of upgrade? Would such a job involve tearing up wooden floors/walls etc? And finally, most importantly what would we be expecting to pay for this...!Any advice appreciated...Thanks!
