if one uses 2 kilowatts, that is the heat you get out? We have storage heaters (5KW) that store their heat overnight in bricks then let it out during the day. Would a new one be any more efficient or is there a physics law about electricity-heat which means they are all more or less the same?
are some electrical heaters more efficient or?

No, all the heaters of the same power are identical and produce the same amount of heat.
You could run the 5000w heater for 1 hour or a 500w heater for 10…it’s the same amount of heat.
Electric heaters are a resistive load, there is no way to make them more efficient. The “physics” law is Power = Voltage X Current. The ONLY way to make it more efficient is in the fan that blows the heat,…if there is one.
Go to http://www.energystar.gov. You will not find an Electric Heater anywhere on those pages.
no they aren’t the same…..look 4 the ones that have the energy star….could have the same kilowatts & one be more efficient than the other.i believe the higher the star rating the cheaper it is to run putting out the same amnt of heat.in comparison to non energy efint one or one with a lower number.
A resistive load will use 100% of the electricity. example: 1 watt in equals 1 watt of work out. Now, the efficiency rating comes for the inductive loads with in the appliance, the motors. Motors are moved by inductive force also known as magnetism. It is the ease of motion which will dictate the motors efficiency.
