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.
 
Hi Croppie, thanks for that. I plan to get it serviced and get an efficiency check done on it. If it still happens to use a lot of oil what do you folks think I should do? Could there be something wrong with the way it is set up? Do you guys think this is an excessive amount of oil for the 2.5 week period or am I just worrying about nothing? Sorry, I'm not a plumber and don't know much about this stuff. Thanks. GSM.
 
It'll be using more oil because the internal surfaces will be dirty. Soot acts as an insulator. For your boiler to achieve its rated output it will need regular TLC.
 
As croppie said with the servicing and reasons, i work that out at roughly ÂŁ2.90 a day for your hot water and heating.
not to mention it is fairly cold and as such the boiler will work harder, without the servicing that just makes it that pinch worse.
If your boiler burner set up is over sized then that could have a small impact.
is the boiler an external one?
what make is it?

post up on here in the i'm looking for a plumber section for a competent and qualified engineer.
never know you could have me!
 
the little hole in the burner nozzle gets bigger over time, so more oil escapes out of it, its that simple, when a manufacturer reccommends an annual service, it's not without reason! As mentioned in another post, a customer of mine just got an estimate of ÂŁ1500 to get his boiler in a state it might work today, he hadnt serviced it for 5 years!
 
Bet the baffles are welded in comon problem with the Worcester. When its been serviced see how you go and then ask the relevant questions.
