How to determine the size of electric heating tube?

Many users of electric heaters ask us how to determine the wattage of an electric heater. Once the wattage is determined, how do we determine the size of the heater? Today, we'll explain how electric heater manufacturers determine the size of electric heaters.
1. Determining the Wattage

The following three parameters can provide a rough estimate of the wattage:

1. If heating liquids, the required volume of liquid (tons or kilograms), the heating time difference, and the heating temperature difference.

2. If heating air, the required space (cubic meters), the heating time difference, and the heating temperature difference.

With these three parameters, a professional electric heater manufacturer can estimate the required wattage.

2. Determining the Installation Space

After determining the required wattage of the electric heater, you also need to determine the installation space that can accommodate it.

For example, a 1x1x1 water tank cannot accommodate a 1.2-meter-long heater.

The installation method must also be considered: horizontal or vertical.

This helps determine the optimal length of the electric heater.

3. Different heating media have different proportional relationships.

This is a key factor in electric heater design. For water heating, the heating pipe has a power output of 3 kW per meter. For oil heating, the heating pipe has a power output of 1.5 kW per meter. For air heating, the heating pipe has a power output of 1 kW per meter.

Finally, the required heating pipe size can be calculated based on the installation length and the proportional relationship.
