Hello
I'm being told by some gas engineers that with all appliances operating at full input, the maximum working pressure difference between the meter outlet and any appliance inlet not greater than 1mbar is acceptable (i.e. cooker - 0.47 mbar boiler - 0.86 mbar heater 0.57 mbar is ok). So the total exceeds 1 mbar but as long as each individual appliance is below 1mbar its a pass
I'm then being told by other gas safe engineers that the total for the whole system has to be below 1mbar (i.e cooker - 0.47 mbar boiler - 0.86 heater 0.57 = 1.9mbar is not acceptable because it exceeds 1 mbar).
Can anyone please confirm what one is the correct method. Many Thanks
