Being an anorak, just boiled exactly 1 litre of cold water from the cold
mains tap in my pretty old 2.2kW kettle. 2 min 30 secs.

So looks like an induction hob is wasting quite a bit of energy. Probably
heating the heavy pan needed.

You don't need a heavy pan.
The approx half millimetre pressed steel pans work fine for boiling stuff.
Just be careful if frying in them as they get hot rather quickly. The
non stick coating and oil then burn.

Which would be less of an issue when
actually cooking something for a time.
