Dennis, there is a vast literature on the subjects you have been
talking about, much of it where people actually worked the numbers.

Re cooling, there is rule of thumb number anyone can calculate on the
radiator area you need per kW of waste heat at room temperature.  I
suggest you might want to look up the formula and calculate it.

There is a subtle problem with scaling down heaters like induction
furnaces and scaling up radiators.

Best wishes,

Keith
