I am thinking of changing my 'glow-warm' back boiler with more efficient condensing combi. The problem I have is the gas pipe that is terminated in my kitchen is 1/2 inch and not 22mm. If I was to connect Baxi 105 HE (which should normaly give me flow rate of 12 litres per minute) to a gas supply comming from 1/2 inch pipe, what should be the impact on flow rate. Does it depend on the gas pressure, i.e if there is enough gas pressure will it still deliver 12 l/min or I need to go for a less powerful model (e.g. 9 l/min)?
Thanks for you advise.
