Surely an Aga has got to put put more than 400W.... 4kW perhaps...

Definitely not. The maximum is about 1kW and that is after a major
cooking session. In steady state it is no more than 750W with gas or
oil models because the burner modulates.

Am I missing something here. How do you cook on 1kW ?

Recently installed a 9kW total hob and I had to agree with somebody here
(Christian) that a good gas hob would still be faster.
