What's the most powerful combi you can get? I haven't seen much
above
35kw.

40kW units are available from a number of makers. Some like Man do
76kW
one IIRC (you will need a pretty serious gas supply for that ;-)

What are the limitations of a "standard" gas supply? I have a 3
bedroom detached house.

M.

Around 60kW.

62.13 kW in fact. In reality you can go about 25% over that as the U6
meters have 100% overload. But private sharks Transco will only stick
to
212 cu foot/hr and charge to uprate.

Don't forget that you have to allow for other appliances like hobs and
ovens in that, so practically maybe 50kW....


A spec. is a spec.

Precisely.

I think it's a bit like saying that you can get 16A from a 13A plug.
Which no doubt you can (since the fuse will likely not blow
for hours if at all).

Balls!!! I used to design gas systems in the 70s. U6 meters have an 100%
overload. We would take them up to 350 cu foot an hour. Go to your meter.
Take off the outlet pipe and fit a 1" hose to outside, then turn on the
maintap. Time the dial for 30 secs or a minute. See how much gas it then
passes for an hour. I bet it is more than 212 cu foot an hour.
