So in theory the maximium demand for the hob 15 minutes before a dinner
party and everything running late is 10Kw.
Is this likely to have a major impact on the size of the gas supply pipe and
will it suck gas backwards through the combi :-)

Seriously, will a 15mm supply be O.K.?

Looks like we will be running a seperate new feed to the combi.

If your gas supply pipe is undersized, the gas pressure falls away and
all the appliances run at less than full output. This is noticable on
a gas hob, the flames will be smaller. And get smaller as other
appliances are turned on.
Just as you might expect.

Just as with electritcity cable, both diameter and length of the pipe
are factors.
