To heat the air, the ratio of the total length of the heating zone to the power of the heating element we choose should be between 1 and 1.5. If the power is higher than this range, the life of the heating element will not be too good.
2, heating water
For heating electric heating elements, the ratio of the total length of the heating zone to the power must be between 1-4 KW and 4 kw is the maximum. If this range is exceeded, the greater the power exceeds, the shorter the life of the heating element.
When selecting the electric heating element for oil heating, the ratio of the total length of the heating zone of the fuel tank to the power is required to be between 1-2. In the case of better oil, the power of 2 kW per meter is the maximum. How to choose the right electric heating element to integrate the above conditions, not only must consider its material but also its power design, both of which are indispensable.
(3) Heating drinking water: At this time, it is necessary to use food grade 316 electric heating element.
Under normal circumstances, stainless steel 304 heat transfer oil furnace electric heating element can also be made of iron. The iron material is lower in cost than the electric heating element made of stainless steel 304, but is more likely to rust.
