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.

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). However on a hot day with a 99p 4-way
extension lead feeding a cheap plug that _claims_ to be BS 1363 and CE
approved (but is made and bought on cost for the sheds by Fook Yu of
China) you can expect trouble.
