Does anyone know the requirements for ventilation of a cupboard containing a gas meter, and would it differ if there were 2 , or more meters? In particular, trying to find out the size of vent required. tia Hugh
I can't think why there should be any need to ventilate a cupboard containing a gas meter specifically. All restricted volumes are going to be better if vented to fresh air as eventually without ventilation it will started to smell stale or worse.
Thanks Bob, but I believe there is an requirement and probably a specification. The logic being, of course, that if there is a leak however tiny, it can't build up into anything serious with continual ventilation. It's just that someone asked me, and I remember about 2 years doing a conversion and we had to install a vent in a meter cupboard, but can't remember any other details! It's old age creeping on!
Ah! I see the logic. Given the probability of a leak is pretty low then the probability of a second leak on the other meter is incredibly low so rational argument should sayt that the ventilation need be no greater for multiple meters. However those who make the regulation do not always follow logic.
My gas meter is in our larder with no explicit ventilation other than if we want to eat, we need to open the larder door at least daily. Our meter was swapped for a digital (cyclometer type) type a few years back and the fitters made no comment. The house is about 80 years old and has been on gas since pre natural gas days.
You might find the answer on 2jags website (search odpm?) if it is covered by building regs.
