I currently have a back boiler which I intend replacing with a Worcester Greenstar 30CDI conventional boiler installed in the loft.
I have read some threads about putting in a separate isolation point to isolate the boiler alone and this seems like a good idea. I have god flor boards, lighting and loft ladders etc so no problems here.
My problem is with the length of gas pipe I will have to use. The gas pipe from the meter to the existing boiler is about 11m in length at 22mm. To go into the loft I intend connecting to the existing pipe and extending. This will make the pipe length about 18m at 22mm. Is this OK or will I have to reroute the pipework?
Also, Is there a minimum height that the feed and expansion cistern needs to be above the boiler?
TIA for any advice.
