How many watts does a radiator use?

Answer 1

Do you mean how many watts are used to make hot water? It varies, but a typical home electric hot water heater consumes about 4,500 watts. Industrial hot water heaters might use 20,000 watts or more! I have a little warmer that keeps my coffee warm as I type this, it consumes about 300 watts. Of course it only heats 6 ounces of water....

Answer 2

Water heaters usually use 2-3 kW but are controlled by a thermostat so they go off when the water in the tank is hot. A hot bath takes about 6 units of electric energy, a shower half that or less.

Answer 3

depends how long you shower for. if your shower is rated 6kW and you shower for 30 minutes then:

total watts = (6 * 1000 )* 0.5 = 3000 Kwh

Answer 4

A bath uses 4-5 kilowatt-hours of energy to heat the water.

Answer 5

The number of watts a radiator uses varies. The device will have a rating printed on it.
