Combination boiler.? We are getting the boiler changed in our house (Worcester Bosch 30)....
We are getting the boiler changed in our house (Worcester Bosch 30). What sort of gas pipe do we stipulation to connect the boiler? At present we have below 20ml. 2 different pipes are coming from the D to the boiler which is below 20ml. Do you think this pipe is biddable enough to run the hot hose and central heat? If anyone could answer this it will be highly appreciated. Thanks.
Answers: Your corgi registered heat installer should know all this,if he doesn't,get hold of someone who does.
just have a new boiler fitted myself and the gas inlet pipe is 22mm
