Description

Electric boiler heating element is the key of part of the boiler,it is a special electrical component that converts electrical energy into heat energy. Because of its high thermal efficiency, easy use, simple installation and no pollution, it is widely used in various heating occasions, and is used more in electric heating boilers. The service life is very long, and the general design service life is more than 10,000 hours.

The characteristic of the electric boiler heating element is that the water in the boiler is not charged. However, when the electric heating element leaks or bursts, it will also make the water in the boiler electric has leakage. In addition, due to the insulation degree of the insulation layer of the electric heating element, there is a certain leakage current in the electric heat pipe. According to the national standard, the leakage current should not be greater than 0.5mA. Therefore, there should be leakage protection on the electrical line.

Stainless steel hot water boiler element adop stainless steel tube coat, modified magnesium oxide powder, high-performance nickel-chromium electrothermal alloy wire and other materials.

Installing boiler heater is a manageable task if you follow the correct steps. Safety is first ,so start by shutting off the power supply to the boiler and turning off the water inlet. Next,drain the boiler tank until the water level is below the old element. Using a proper eelement wrench to remove the old heating component. Clean the threads on the boiler tank and screw in the new element, ensuring the gasket creates a tight seal to prevent leaks.Only after you have confirmed there are no leaks should you restore power and test the new electric boiler heating element.

When it is working, there is a current through the high temperature resistance wire, the heat generated by the magnesium oxide powder diffuses to the surface of the metal tube, and the heat energy is transferred to the water in the boiler to achieve the purpose of heating.

With its excellent performance and wide applicability, our electric boiler heating element has been widely used in commercial, industrial, civil and other fields. In the commercial sector, hotels, guesthouses, baths and other places have a large demand for hot water supply and heating. Electric boiler heaters can provide a stable and efficient heat supply for these places.

In the hotel, the rapid heating feature can ensure that guests can enjoy warm hot water at any time, improve guest satisfaction; In the bath, the high-power heater can maintain the constant temperature of the pool water, providing customers with a comfortable swimming environment.

In the pharmaceutical industry, the temperature require is more stringent, boiler heater can provide accurate temperature control to meet the heating needs of the drug production process, to ensure the safety and effectiveness of drugs; In the food processing industry, whether it is baking, cooking or sterilization and other processes, we need reliable heat energy support.

How to choose the material of the boiler element?

Normal boiler is to heat water,so the material of the boiler heater element should be made according to the water condition.

1. purified pure water, drinking water is suitable for stainless steel 316 material (food grade stainless steel).

2 Some water quality is relatively hard and easy to get scale areas ,considering choose the stainless steel 316 material for the boiler element.

3.Some area which has good water without water scale,we suggest using stainless steel 304.

Which type is more suitable for the electric boiler heating element?

The best solution is flange typle heater element! The design of the flange heater element is suitable for electric boiler element,flange welding can be convenient to assemble it in the side of the boiler or bottom.This connection way promise the firm connect and can be avoided for the energy loose and leakage.

Boiler heating require fast heating ,flange type boiler element has high efficiency in heating conduction ,and uniform heating promise the boiler working efficiency.

Flange type hot water boiler element has the good ability in anti-corrosion,it can prolong the life of the boiler heater element and decrease the maintenance.
