After ditching our plan to install electric raditors we've decided to bite the bullet and install central heating - probably oil fired. Haven't investigated at all yet, but am looking for a very rough costing - from scratch, all equipment, including tank and installation - for a six room stone cottage needing about eight radiators. Most of the internal walls are 70 cms thick. We're near Agen, Lot et Garonne. What do you reckon I might be looking at - 3000, 5000, 10000 Euros? More? Thoughts welcome. James
