A 5kw heater draws just that, 5kw or 5000 w. If you have that switched on high, well I do not know what your supplier charges per kw hour, I am glad its not me paying.
The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps
Volts times amps equals watts, so the question is - what times 480 makes 10,000, and the answer is 10,000 divided by 480. That is 10,000 divided by 500 and then increased by 4% which is 20.8 amps.
Both work just as well. The only difference is what the supply voltage is at hand. Heaters are rated in watts. Your electric bill is rated in watts consumed per hour. Watts = Amps x Volts. An example, 500 watt heater at 120 volts will equal 4.16 amps. The same heater at 240 volts will equal 2.08 amps. As you can see if the voltage goes up the current goes down but the wattage total is always the same. That is the reason that you are billed on wattage, and not on what the service voltage or the current draw of the service is.
In North America 240 volts.
I think you need to do some checking, A GAS water heater does not normally need electrical service that large- an ELECTRIC water heater will. So- just what do you have- gas or electric?

A label.
If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.

The formula you are looking for is I = E/R. Amps = Volts/Resistance.

There are small water heaters that run on 110 volts. However if yours is a large 240 volt heater and you only have 110 volts going to it, then it is fused and one on the fuses has blown in the service panel.
Voltage is current times resistance, 1.2 x 110 = 132 volts.
Yes you can run a 400 volt heater on 230 volts but you will not get the full wattage rating that the heater produces at 400 volts.
1600 watts is unusually low for electric baseboard heaters! These usually are rated at about 6000 watts.Typical electric baseboard heaters operate on 220 volts thus you heater would pull about 7.3 amperes and 16 gauge wire can easily handle this.A standard 6000 watt baseboard heater pulls about 27 amperes and needs 10 gauge wire.
