An immersion heater typically uses around 1500-2000 watts of power when heating water. The exact wattage can vary depending on the size and type of the immersion heater.
A 3000 W water heater is 3 kW water heater. For 30 minutes of operation it would be 3 kW multiplied by 0.5 hours, or 1.5 kWh. One kWh is equal to 3,600,000 Joules, the water heater uses 1.5 times 3,600,000 J, or 5,400,000 J.
If you mean an immersion heater for making hot water, they use 3 kW usually so you get enough for a bath in about two hours.
A 700 watt small heater consumes 0.7 kWh of electricity in 1 hour. In 5 minutes, it would consume 0.0583 kWh (0.7 divided by 60, then multiplied by 5) of electricity.
Yes, an electric heater will use less kWh on a lower setting since less power is being consumed to generate heat. Lower settings require less energy to maintain the desired temperature, resulting in lower energy consumption overall.

No it is not expensive
An immersion heater is used to heat water for purposes such as bathing or showering. The amount of hot water produced depends on how long the heater is switched on for.
A 3000 W water heater is 3 kW water heater. For 30 minutes of operation it would be 3 kW multiplied by 0.5 hours, or 1.5 kWh. One kWh is equal to 3,600,000 Joules, the water heater uses 1.5 times 3,600,000 J, or 5,400,000 J.
To calculate the cost per hour for a 400W heater, you need to know the electricity rate per kilowatt-hour (kWh) charged by your utility company. For example, if the rate is $0.12 per kWh, a 400W heater would use 0.4 kWh per hour (since 400W = 0.4 kW). Multiplying 0.4 kWh by $0.12 gives you a cost of $0.048 per hour to run the 400W heater.

100 kWh
There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs
A 700 watt small heater consumes 0.7 kWh of electricity in 1 hour. In 5 minutes, it would consume 0.0583 kWh (0.7 divided by 60, then multiplied by 5) of electricity.
Yes, an electric heater will use less kWh on a lower setting since less power is being consumed to generate heat. Lower settings require less energy to maintain the desired temperature, resulting in lower energy consumption overall.
To calculate the cost of running a 1500 watt heater, first convert the wattage to kilowatts by dividing by 1000 (1500 watts = 1.5 kilowatts). Next, multiply the kilowatts by the number of hours the heater will be running per day (let's say 8 hours for example). Finally, multiply this by the cost per kilowatt-hour (111748 kwh) to find the total cost per day.
A 200W light bulb will use 0.2 kWh (kilowatt-hour) of electricity per hour of operation. If the bulb is on for 5 hours, it would consume 1 kWh.
