Hi all. Moved into our new build in November - 2900sq ft, 5 bedroom, storey and half. We have 20 rads all varying in sizes. Anyway, we got 500 litres of oil in September to dry out the house before we moved in. We were told by the oil crowd that it would take 2 or 3 fills of oil to dry out the house properly. At this stage we had the heating on for maybe 4 hours a day to dry out. We moved into the house on the weekend of 21 November and that weekend we actually ran out of oil.. 500 litres gone! We got a full fill of 1016 litres on Mon 24 Nov. Again it was timed to come on for hour in morning and 2 in evening....plus the odd time for an hour here and here when it was very cold. Then on 12 Feb we got a top up and it needed 682 litres...so we had used 698 in under 12 weeks?? Is this normal. The house is split in 3 zones - 2 downstairs and 1 upstairs. Upstairs is off most of the time so thats 15 rads left...any suggestions?
