HELP!! Gas meter/supply under sized

[royston]

I was reading about the diversity factors in the corgi book last night, there is calculations you can do.

some info about diversity factors that people might find handy. I have an issue on a job where the u6 meter might be too small for a new 40kw boiler and existing appliances so rang gas safe and they said when sizing a meter you only need to take into account

100% of gas consumption for a conventional boiler
60% for cooker
40% for gas fires

Think you might have swapped the figures for cookers (40%) & fires (60%).

Here is how to do it

Not much diversity on three combis? What was the installer thinking about. The poor old gas meter must be knackered.

Yeah, they never came to read it, just came to change the bearings!

the real bad news is your gonna see a rise in your gas consumption assuming at some point the three boilers were under gassed
