My mate says that a domestic gas engineer can work on up to 70kw appliance when there is other appliances as long as there is an isolator before appliance.
I say that the whole installation from meter to all appliances must be 70kw maximum.
Trying to look in books for answers, I have bpec and logic books but can't find it!
Can somebody point me in correct direction please as would really like to prove either way.
Also I know that the 70kw boiler would be too high an installation volume and pipe size but he believes that as long as it is from isolator then all of this doesn't matter!
