What is the cost of heating 1000 liters of water by electricity?

The cost of heating 1000 liters of water using electricity depends on several factors, including the initial temperature of the water, the desired temperature increase, and the cost of electricity per kilowatt-hour (kWh). To heat water, you typically need 4.18 kJ to raise the temperature of 1 liter by 1°C. For example, heating 1000 liters by 30°C requires about 125 kWh. If electricity costs $0.12 per kWh, the total cost would be approximately $15.00.
