10000 divided by 220 for a resistive load.
Slightly more than 11 amps. <<>> I = W/E I = 2500000/220 = 11364 amps
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.
Assuming no other factors are considered, a 3kW geyser would draw approximately 13 amps of current on a standard 230V electrical supply. This calculation is based on the formula: Power (in watts) = Voltage (in volts) x Current (in amps).

The formula you are looking for is I = W (VA)/E. Amps = Watts/ Volts.
To calculate the number of amps, you need to know the voltage of the circuit. Using the formula Amps = Watts / Volts, if the voltage is 120V, then 9.8kW at 120V would be approximately 81.67 amps.
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.
