Condensing boiler using alot of oil.

[GSM]

Hi Folks, had my boiler serviced yesterday, service guy replaced the nozzle to a 0.65 (less than half the size of the previous nozzle) and rated the boiler down to 24Kw. The boiler is a condensing Worcester Greenstar Utility 32/50Kw Model: BFC. Hopefully I should see a difference in the amount of oil consumed. What do you folks think? I'm going to keep an eye on it to see how it goes. Thanks GSM.

I wonder if it has the adapted blast tube?

Tbh sounds like the boiler is way oversized. Especially if its now rated to 24kw which in its own way will cause issues.

He's rated it down to 24kw? Well that's asking for trouble.....

 

[Bunker]

Well it wont dry cycle thats for sure...

Gonna cost you more in oil because the boiler's going to struggle to hit its temps.

Deja vu this. Had this very convo earlier today!

Not to mention with the additional restrictions it will struggle to clear POCS and soot up faster...

Almost certainly condense in the primary heat exchanger.

Your boiler man is just that a boiler man he has turned it down to low
It's a big house the boiler sounds sized correctly to start with now nooo

Wonder if the boiler engineer rung Worcester to check pp and CO2, because the lowest nozzle you should have is a 0.85 by the MI's.
He would of had a bit of fun setting that up, wonder if he will answer his phone next year??
We get a few of them round our way, turn up break things, never to be heard of again!
