Central Heating Question

Is it possible to have two gas combination boilers connected to the same gas meter?

I'd like to have two gas combination boilers (one downstairs the other upstairs, and serving likewise) connected to the same gas meter. The problem is I have received confusing messages from builders, some saying that I can, some that I cannot have that on one meter.
The room upstairs is rented out and ideally I'd like the tenant to be able switch her own heating there on and off. But as I'm the one paying gas bill for the whole property, I do not see why I need the second meter. Any advice please?

Hi turquoise

If you are responsible for paying the gas bill then you dont need a secondary meter , the olny thing you need to ensure is that the gas supply pipe is big enough to supply both boilers along with any other load that will be in use ( eg cookers )

PS all you would need in the room above is a emergency control valve and a gas test point, at the point where the gas pipe enters the room.

100% agree with Regal Heating.

Calculate the full load, inform gas transporter, (They will decide wheter the existing meter will surffice / needs changing).

If you only want the upstairs / rented accommodation to have control of their heating independantly then why not consider installing zone valves, from the one appiance ?

This set up is industry standard on all new properties, I.E. One time clock / programmer / thermostat controlling one zone, say 'Upstairs', and the other, (or more than one other !), controlling other parts of the property !

This would work out considerably cheaper than going to the expenses of a second appliance.

Why not post the job on this site ?

An experienced heating engineer could advise you of the most cost effective options available.
