Boiler flue - am I being told the truth?

[holty]

But are we talking gas or oil.

proberbly the most important question of all.

keston gas fired boilers will allow flue up a chimney and it aint as expensive or cotroversail as the poujoulet system which to my knowledge still doesnt meet any bs or any manufacturers recommendations.

Atmos is one of the best Combi's on the market and is suitable for a flue liner connection.

IF ITS GAS FIRED.

and you can recommend these boilers because personnaly you've fitted how many

None But Dan Robinson fits nothing else

And I'm sure you know him.

The reason I assumed that it would be cheaper to vent into the chimney is because the existing (gas) boiler vents into it.

Gigz is right in that I cannot assume there is an existing flue liner in chimney. I have made an assumption on this point which would need to be checked.

Due to my ignorance, I assumed that a new boiler would be able to use the existing flue liner (assuming one exists!). I had also assumed that a flue liner is a simple metal tube but now understand that some are more sophisticated than others (allowing air in and exhaust gasses out) and that some boilers require these more sophisticated flue systems. This being the case, it may be easier (and therfore cheaper) to vent vertically as two heating engineers have already suggested, rather than installing a special flue liner in a chimney.

Many thanks everyone for your helpful advice.
