The causes and solutions for the scaling water tank electric tubular heater: 

We know that whether it is a domestic hot water kettle or an industrial water tank, the pot wall and the surface of the electric tubular heater of the water tank will be full of scale after using for a long time. Many customers will ask, water tank electric tubular heater scaling speed is what, what can be done to reduce scaling?

There are two reasons for the rapid scaling of electric tubular heater of water tank


1. The water quality heated by electric tubular heater of water tank is hard.

2. There is something wrong with the design of the electric heating pipe.


Normal electric tubular heater heating water per meter power design between 1-3kw, but some customers in order to save costs per meter power design to 4kw or more, so the greater the surface load of the electric tubular heater, so the higher the surface temperature of the electric tubular heater, the higher the speed of scaling on the surface of the electric tubular heater, so the scale will be more.


The above two are the main reasons for the serious scale. The methods to slow down the scaling are as follows:


1. In areas where the water quality is relatively hard, the water can be purified and then heated.


2. Reduce the surface load of the electric tubular heater of the water tank, and the normal power per meter should not be higher than 2kW, so as to slow down the scaling speed of the electric tubular heater of the water tank. Or the electric tubular heater of water supply tank shall be treated with waterproof scale coating.
