My son has a Vaillant Ecotec pro28 in the loft with a flue going up through the tiled roof. The boiler is one of the first of this model dated 2006 so is due for replacement. Could the current model of the Vaillant Ecotec be installed to use the existing flue. The boiler is on a flat wall between the houses (semi- detached) so there is plenty of room. The reason is to save the cost of a new flue to be installed on the roof i.e. scaffolding, roof tiles etc.
Re-using combi boiler flue ?

+1, never re-use an old flue.
Both above answers are technically wrong what the regs state is the flue should last the lifetime of the appliance .
And as the existing appliance is 16 years old then its highly likely that the flue will not last the lifetime of the new boiler so new flue at same time

.... OP .... So technically ..... it's a new flue in this case probably , but as i said technically not all the time .
Jeesh ... ... it really should have a new flue ... that's all the OP was asking.

I do, I pass my ACS every 5 years just like you and every other GSR engineer but as it was a DIY question as to whether the flue should be used or not, I think the answer given to the question was all that was needed rather than having to be so technically correct just to have a go, IMO there's honestly no need.
Certainly not on someone else's post.
That's a very roundabout way of agreeing that the flue should be replaced, which is what we said
no its stating what is required and not what you said about flues MUST be replacedThat's a very roundabout way of agreeing that the flue should be replaced, which is what we said
Edited to satisfy your pedantry
But we hope that the boiler will be replaced by a gas registered installer and he should make the decision about the flue.
Modern flues with plastic inner tubes might last a little longer than the usual 10-12 years. But it all depends on the condition of the old one which is already older than the usual boiler lifetime.
A friend had a long horizontal flue on a Vaillant and it was badly fitted and it had to be renewed after just three years.
If your's was in very good condition the installer might agree to postpone the renewal for a few years but because he would then have no control on ensuring it would actually get done, most would expect to replace it with the new boiler.
