The requirements for the diameter of the gas pipe?
The gas pipe connected to my combi boiler VOKERA linea is 15 mm, If I want to replace for a new boiler is it any options , which would satisfy the latest regulations? Ideally I wouldn't like to change the gas pipes,but only to replace a boiler.
It is normal for the last few feet to be 15mm.
However, the general run of pipe from the gas meter will be 22mm unless it is a long run and there the answer will depend on the distance.
