Replacing Gledhill Gulfstream

[Anders0n]

Got called to one of these monstrosities the other day and customer has agreed to replace it.

Only problem is the flue is over 17 metres vertical (ground floor flat). Thats not including the 2x 90's and 1x 45.

Does anyone know of a 24kw combi that lets you have a flue such a length?

Or better yet a boiler which will let me use the existing flue?

Thanks in advance.
