How to Choose the RightHeaterFirstly, the power size of the heater must be considered. The selection of power is to meet the heat requirement of the heating medium, ensuring that the heater can achieve its heating purpose and operate normally under the condition of meeting the time parameters.
Since the thermal efficiency of electric heating is approximately 1, it can be considered that: the power of an electric heater is equal to its heat output.
The calculation of power should consider the following three factors:
From the initial state, the heating medium is achieved to the set temperature (working temperature) as per the required timeline.
Under operating conditions, the heat output is sufficient to maintain the medium temperature.
There should be a certain safety margin, typically 1.2.
Clearly, selecting the larger of the power options from (1) and (2), and then multiplying by the safety margin is the recommended power choice.
