Depends on the waatage of the immersion heater. Read the name plate details of the heater - it shows the wattage of the heater. Assuming the wattage is 1KW (1000Watt) the KHW will be 1KHW if you use the heater for 1 hour.
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.
700/(60/5)= 58.333 Wh 58.333/1000= 0.0583 kWh
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.
The wattage of an immersion heater typically ranges from 1,000 to 3,000 watts, depending on the model and its intended use. Common household immersion heaters usually operate at around 2,000 to 3,000 watts for efficient heating. The specific wattage will be indicated on the heater itself or in its specifications. Always check the manufacturer's guidelines for precise information.
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
To effectively use an immersion heater for a bathtub, fill the tub with water to the desired level, then submerge the heater and turn it on. Monitor the temperature to ensure it doesn't get too hot. Once the water reaches a comfortable temperature, you can enjoy a relaxing bath. Remember to follow safety guidelines and never leave the heater unattended.
To effectively use an immersion water heater for your bathtub, fill the tub with water to the desired level before submerging the heater. Turn on the heater and wait for the water to reach your preferred temperature. Stir the water occasionally for even heating. Once the water is warm enough, turn off the heater and enjoy a comfortable and relaxing bath. Remember to follow safety precautions and never leave the heater unattended while in use.
