To be more specific, if i have to heat water 300l of water in one hour. What should the power of a heating coil?
How can we calculate the power of a heating element?

SUMMARY
To calculate the power required for a heating coil to heat 300 liters of water from room temperature to boiling within one hour, one must consider the energy loss due to heat dissipation and the insulation of the container. A specific calculator available at this link can assist in determining the necessary energy and power. Additionally, safety precautions are paramount when using a pressurized electrical cooker, as improper handling can lead to dangerous situations.
PREREQUISITES- Understanding of thermal energy transfer
- Familiarity with heating coil specifications
- Knowledge of insulation properties
- Basic principles of pressure cooking safety
- Research the calculations for heating water using the specific heat formula
- Explore the use of thermal insulation materials for heating applications
- Learn about the safety standards and protocols for pressure cookers
- Investigate different types of heating coils and their efficiencies
Engineers, appliance designers, safety inspectors, and anyone involved in the design or operation of heating systems, particularly in pressurized cooking applications.

This calculator will help you figure out how much energy and power are required to heat your water from room temperature to just short of boiling:Bhisma Thapa said:

After that, it depends on whether you want to actually boil off the water, or keep it boiling for some period of time. Also, unless your container is perfectly insulated, you will lose some energy to the surroundings...
Can you say more about the application?

Power is the rate of energy flow. You must deliver energy at a rate greater than the heat loss by all processes over all temperatures.Bhisma Thapa said:
How quickly do you need to heat the water?
How well insulated is the tank?

Thanks.berkeman said:
It will be used like a pressurized electrical cooker.

Be careful and very vigilant about safety. It takes only one mistake to turn a pressure cooker into a bomb able to kill everyone in the room.
