I have an electric heater which is rated 2000W, 230V .
Is it that the OUTPUT (thermal energy/coming out as hot air) is capable of transfering 2000J of energy to the surrounding room per second ?
OR
The heater needs a 2000J of electrical energy per second to power it (at max) so that it then transfers some unknown ("x" amount of thermal energy which is less than 2000J ofcourse dependant on the efficiency) heat energy to the surrounding air in the room .
Which one is True ?
