Evening all. I'm just pricing up my first Aga flue job and have a quick question regarding k-vent and b-vent. Now, including the flue above gutter height total external length will be somewhere between 4 and 4.5m. Now as you can only use b-vent type flue up to 3m externally, can you mix and match on the external run? For example use 3m of b-vent and do the remainder in k-vent.
I've already seen a quote from another installer coming in at around the £750 mark but running the external length in k-vent the materials are around £650 inc VAT whereas b-vent is about 1/3 of the price. I can only think the other installer is quoting using b-vent for some or all of the external run. Or fitting an Aga flue for £100!
So yeah, advice appreciated.
ps - I would have put this in the RGI section but i've filled the form in 3 times now and haven't got a reply so have given up!
