What I don't understand is why a 1.3KW heater would be better than a
2KW at giving out heat.

It *might* be better, if. e.g. the 1.3kW can operate at 100% duty cycle,
but the 2kW keeps hitting its overtemp stat and operates on less than a
65% duty cycle.

The other thing that came to mind is that he would probably get more
heat out of the radS with them all on (and potentially maintaining)
the 1300W element than with them all trying to run both (at ~2kW
total) because of the voltage drop from the crap power supply.

And with that supply he'll probably be getting as much heat out of the
ring main as he will the heaters themselves. ;-)
