Sounds like an option. I guess the whole point with induction is to use an appropriate pot with enough iron content so it actually works.
Have you got any links to the kit?
If I'm not mistaken, @Halfacrem bought this one to use with a Ss Brewtech 10 gallon kettle

Induction hobs are for more energy efficient than conventional electric hobs or gas. They have an energy transfer efficiency of 84% versus just under 50% for gas, so a 3000w induction hob is not much less powerful than a 7.5kW gas burner.
