which condensing boiler

[mpj]

I am looking to replace my Vokera combi with a new condensing boiler. All suggestions point to a Worcester Bosch but they require a 22mm gas feed from the meter which is unfortunatly a long way from the boiler and under the floor. So I am looking to find a boiler with a half inch gas feed as with the Vokera. I have 9 radiators and 1 bathroom to supply.
Any suggestions ?
Thanks.

If you are using a system boiler then the feed is possibly (!) enough, if it is a combi then your feed will be undersized. This is in no way desirable.

what distance from meter to boiler ?

Quite - if it's a "longway" and you want a combi , especially 28 kW or more, you'll need 28mm.
It's often more of an undertaking replacing the pipe than the boiler!

Even though a boiler of any description has a 15mm gas connection, it's odds on it aint going to get enough gas if it's a long pipe run from the meter, if it's a combi there is even less chance of it getting enough gas when calling for DHW, I wouldn't fit a combi of any description with 15mm pipe.
