Hi Folks, I just wanted to ask about the oil consumption of my condensing boiler. It is a Worcester boiler which was installed and commissioned 2.5 years ago. The boiler achieved an efficiency back then of 98%. I have been keeping a close eye on my oil use recently and feel that it is excessive. Over a 2.5 week period I have used 85 litres of oil, I only have my hot water zone on for 40mins and my first floor radiator zone on for 1 hour in the mornings and in the evenings my first floor radiator zone would be on again for 1 hour. My house is a new build approx. 3500sqft with double glazed windows. My house is well insulated - over and beyond required u-value standards. I have a zone of under floor heating as well which is not turned on (afraid to turn this on as I know my oil level would drop significantly!) I don't understand why I'm using so much oil - I had thought previously that I had a leak, but I checked my oil levels before and after being on holidays on a couple of occasions since we moved in and the oil level didn't drop. I haven't had the boiler serviced since we moved in 2.5 years ago and know that this is something I should organise to get done, but the oil consumption has been high from the start when we moved in. I am thinking that the boiler hasn't been set up correctly or something? I know that Worcester is a good manufacturer and that's why I decided to spend extra and install one. I have friends who have their heating on constant i.e. under floor set a specific temperature and boiler comes on when temperature drops below this and they use very little oil compared to me. Any ideas? I appreciate any help anyone can give me. Thanks very much. GSM.
