Actually in this case he is right about the power proper, but the outcome
is right (see my other posting). The heater in a heat gun, or space
heater, uses heater wire with a low tempco so the resistance is very much
the same whether cold or hot. Unlike lightbulbs etc. For this reason 500W
and 1000W space heaters make great testing loads for higher end audio amps
