extension flu for boilers from mr central heating?

bwatt00

Need some advise i am going to be ordering a new combi boiler from mr central heating has anyone on here ordered from them before and what did they think of them also is there anyone that can beat there prices.
Also i have a guy coming to fit it next week and he said i better order an extension flu of say 500mm incase its needed.
Now has anyone order this as well and can they tell me more about it from mr central heating as they guy was a little rush on the phone as it was closing time and he said something about selling extension flu at .75 of a meter per what ever cost he mentioned.
I will be phoning again to ask friday as i did not catch what he said if anyone has order from them and also extension flus can they tell me what approx cost they paid as im sure they guy was very expensive on that item,im not sure.
My plumber said a bit about say 500mm would be ok and incase it was needed but i did not catch what mr central heating said about the .75 of a meter can anyone help me out here.

It depends on which boiler it is for. If it is for a big named brand like Baxi-Potterton etc then you would be able to get flue extensions from a local merchant.
