Hi-new here, we just got a combi boiler fitted.
I was told we need 22mm supply and old supply was 15mm which ran under concrete floor.Was told it was easier to run gas supply the the length of house to the back with 22mm copper pipe.
The current set up was 22mm from the meter box into the house under floorboarded dining room,which then reverts to 15mm somewhere between the dining room and living room[which is solid floor]
This seems fine but just before it enters the house there the 22mm pipe then reverts back to 15mm and stays 15mm roughly the metre or so to the boiler.
Looking at the manual [its a valliant eco tec] it says it need a 15mm supply,and also states
"Exisiting meter should be checked to ensure it is capable of passing the rate of gas supply required.Pipework from the meter to the boiler must be of an adequate size.Do not use pipes of a smaller size than the boiler gas connection [15mm]"
I`m no expert but this makes me wonder why run 22mm pipe round the house?? wouldn`t it have been easier to simply use the existing 15mm supply that was already in the correct position used with the older boiler???
