10000 divided by 220 for a resistive load.
Slightly more than 11 amps. <<>> I = W/E I = 2500000/220 = 11364 amps
3000w / 220volts = 13.63amps 3000w/ 110volts = 27.27amps
A btu is a measure of energy, but 18,000 btu per hour is a power of 5.22 kW, which is 5220/220 amps, 24 amps.
The formula you are looking for is I = W (VA)/E. Amps = Watts/ Volts.

500,000 watts/240 volts = 2,083.34 Amps (single phase)
The heater should have a wattage rating (very few list amps). Calculate the amps using the wattage and voltage. Amps = Watts/Volts(480).
The amps will be the same. Volts will depend on between which two points you're measuring it.
Typically 75 amps on natural gas, 85 amps using propane. Peak amps(for less than a second) to start a big appliance, like an A/C condenser, are 130.
