Please can anyone tell me the sizes of the gas supply pipes for a Worcester, Bosch Greenstar 30 CDi boiler? The gas will be supplied to the boiler from a gas meter on our outside wall, from the meter 8 meters of the gas pipe will be underground to get to the kitchen and in the kitchen the gas pipe will travel under the floorboards for about 4 meters and it will travel in the concrete floor in the living room for about 8 meters. The gas is supplied to three points whic are the boiler, the hob and the fire place. Please can you tell me what are our options in terms of gas pipe sizes to optimise the gas supply to the boiler, if all of this makes any sense? Thanking you all in advance.

Can't determine gas pipe sizes without seeing job, you have to take pipe length, fittings and other appliances to calculate the correct pipe size.

Going off the pipe length alone it'll probably be 28mm minimum.

The recommended pipe size for your boiler is 22mm. Your gas fire will probably require 10 mm. Those two alone add up to 30 mm (using the comparison of the pipe section areas). What is the size of the pipe leading to the meter?

The connect to the boiler is 22mm - this does not determine the gas pipe size. The RGI has to calculate pipe sizes.
