Grant / Riello burner choice

[Bracken]

I have a Grant Vortex Blue 26kw external oil boiler, installed less than 12 months ago. It's had intermittent non-starting problems resulting in multiple warranty visits, part replacements and eventually burner replacement. The replaced burner I discovered was a 'yellow flame' one, apparently the same as on the Grant Vortex Pro model. Having questioned this with Grant, I've been told that this is as efficient and my longer warranty is preserved but offered to either keep this one with a cash adjustment or have it replaced again with a 'blue flame' one as originally fitted. I'm concerned about having a hybrid boiler but the yellow flame's ability to burn biofuel might be an advantage in the future. Any thoughs or advice would be appreciated.

I would think a burner that has tighter control of emissions is more complicated than the more basic type so you might opt to keep the yellow flame with its added ability to burn biofuel. I have a 18 year old boiler with a very basic Riello G5X burner that has never tripped on any form combustion failure, I certainly wouldn't expect any of the newer type burners to operate like this.

Did Grant give any reasons for the intermittent starting problems?.

Ask for a blue burner, much lower on pollutants from what I remember.

Interested to hear what Grant put the intermittent starting down to.

 

[Bracken]

Thanks both. The cause was never established: both Grant and I got fed up with the attempts and agreed to replace the burner.

A blessing in disguise, you can thrown your used chip pan oil and any old brylcreem + briallintine hair oil that you may no longer need into the oil tank now.

As Grant registered installer's I can give a bit of background information,.
The blue flame boiler was introduced to meet upcoming EU regs which of course never happened.
It was a more expensive boiler plus more expensive to maintain due to requiring new blast tube and other parts on a regular basis .
It has now been withdrawn in the UK and the vortex pro range warranty extended to 10 years (assuming a Grant registered engineer commissions)
Riello did have problems with a small number of burners around 20 months ago the op probably had one of those.
If you check the omissions from the blue flame and the current yellow flame there is not that much difference.
