For example :

The power of electric heating tube is required to heat 100kg water from the initial water temperature of 10 ℃ to 60 ℃ in 60mins (3600s)?

Normal specific heat capacity of water: 4.2kJ/(kg·℃);

Temperature difference: 60-10=50℃

Required power(kw)=The water weight(kg) * Temperature difference * Specific heat capacity of water (kJ/(kg·℃)) / Time (s);

The thermal power is calculated by substituting it into the formula ＝100*50*4.2/3600≈5.8KW.

The power value of electric heating element can be obtained by dividing different electric heating forms by a certain thermal efficiency coefficient (such as 0.8-0.9).

Time required for every 10 ℃ rise of power corresponding to common water tank capacity:

The above table is for closed water tank, not applicable to fluid and thermal circulation system; the default water tank is full water state, if not, it should be converted according to the actual capacity.
