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

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 ) Best regards Regal heating and plumbing 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. Regards, Adrian Hagger
