no, they radiate less total energy because they take 1/3 the time and
radiated power is no different to a 1kW unit, since that depends
entirely on water temp and kettle shape & finish.
Sorry, but the difference in time heating 4 quarts of water in a 1kW
vat is NOT 3 times that of the 3kW unit.
There are constraints. The water has to still be there when you are
done.
If it takes a 1kW unit to heat it to boil in ten minutes, there is no
way in hell a 3kW unit will do it in three.
Of course not! it'd take three and twentyy seconds.
It is NOT linear, chucko.
for a heating element immersed in the water it is almost exactly linear,
do the math.
Bye.
