Semiconductor electric boiler vs electromagnetic electric boiler

Who is really the energy-saving electric boiler worthy of long-term use?

Under the current trend of "electricity replacing coal, electricity replacing gas", electric boilers are widely used in the fields of heating, living hot water and industrial hot water. However, in the actual choice, many users are driven by price and tend to ignore the long-term running cost, safety and reliability.

The mainstream electric boiler on the current market is mainly divided into two categories: semiconductor electric boiler and electromagnetic electric boiler. There are essential differences in principle, performance and usability.

1. Semiconductor electric boiler: the cost is low, but "cheap is not equal to saving money"

Semiconductor electric boiler, in fact still belongs to resistance heating products, its advantages are relatively simple structure, relatively low initial construction costs, so it has a certain share in the early market. However, in terms of long-term use, its drawbacks are obvious.

1. Low thermal efficiency and high energy waste

In the heating mode of the semiconductor electric boiler, the heating body of the semiconductor directly converts the electrical energy into thermal energy through electric current and transmits it to the water. Because of this "multiple heat transfer" method, the heat loss is large and the actual thermal efficiency is much lower than the theoretical value.

Under prolonged operating conditions, users often find: high power consumption, but the effect of creating heat is not ideal.

2.Power attenuation with usage time, performance is not stable.

In a long-term high-temperature working environment, the internal structure of the semiconductor heating body deteriorates and its thermal conductivity decreases.

The actual output power decreases year by year

The heating rate is getting slower and slower

Energy consumption continues to rise

This is also the fundamental reason why many users feel that it is not as easy to use at the beginning after using it for one or two years.

3.Water and electricity are not completely separated, so the safety danger is always there.

Most semiconductor electric boilers are constructed by direct or indirect contact between the heating body and water. If they operate for a long time, have complex water quality and serious scale, there is a potential risk of leakage and breakdown.

These concerns cannot be ignored, especially in places where safety is critical, such as schools, hospitals and central heating.

4. Too much dirt and high maintenance costs.

Due to the repeated heating of water on the surface of the high-temperature heating element, scale is easily formed. Once scaling occurs, it not only affects heat transfer efficiency, but also further accelerates the aging of the heating element, forming a vicious cycle.

The result is frequent maintenance, frequent shutdowns, and short service life.

5. The service life is limited, the total cost is not low

In view of many practical applications, the effective life of semiconductor electric boilers is generally short, and the core parts must be replaced within a few years.

On the surface, it looks like "buying cheaply", but in fact, it doesn't save money.

2. Electromagnetic boiler: true energy saving, safety and long life products

Unlike the semiconductor electric boiler, the electromagnetic electric boiler adopts the electromagnetic induction heating principle and determines its overall superiority in terms of safety, energy efficiency and reliability from the technical path.

1. With complete separation of water and electricity, the safety level far exceeds the traditional electric boiler

In the electromagnetic electric boiler, the metal is heated by the electromagnetic field, and the water is only the medium to be heated. The whole process is not in contact with any electrically charged elements, and the separation of water and electricity is really realized.

This structure fundamentally eliminates the risk of leakage and offers a much higher level of safety than a semiconductor electric boiler, making it particularly suitable for processes with stringent safety requirements.

2. Thermal efficiency is more than 98%, really does not waste electricity once

Electromagnetic heating "generates heat directly inside the metal", has low heat loss and is said to be very energy efficient.

In actual operation, the total thermal efficiency of the electromagnetic electric boiler can be stable and maintain more than 98%, but in the same environment, the power consumption is much lower than that of the semiconductor electric boiler, the energy-saving effect immediately appears.

3.The magnetized water effect significantly reduces plaque and maintenance costs.

During the operation of an electromagnetic boiler, it will magnetize water molecules, causing the scale structure to become loose and difficult to adhere.

Under the same water quality conditions:

Significant reduction in scale

Long term stable heat exchange efficiency

Almost no need for frequent cleaning and maintenance

Fundamentally solving the problem of traditional electric boilers consuming more electricity and being more difficult to maintain as they are used.

4. Stable power without decay over time

The core components of an electromagnetic boiler are the electromagnetic coil and control system, and there is no problem of power reduction caused by aging of the heating element.

As long as the equipment operates normally, its output power remains stable for a long time, and the system performance degradation is minimal.

5. Long life, real long term investment.

The design life of the electromagnetic electric boiler can reach more than 50,000 hours.

Taking our company as an example, the large number of electromagnetic boiler equipment installed in 2015 has been in stable operation for more than 10 years. Most of them are in normal operation and the failure rate is very low, which has been well received by the users.

Third, conclusion: choose an electric boiler, can not only look at the price

Although the initial cost of the semiconductor electric boiler is relatively low, it has problems such as low efficiency, fast decay, short life, high safety, etc., and the long-term use cost is rather high.

Electromagnetic electric boiler has overwhelming advantages in safety, energy saving, stability and service life. It is really mature, reliable and energy-saving product worthy of long-term use in the field of electric boiler at present.

One choice determines the usability for ten years.

The electromagnetic electric boiler is the right choice for the future in the pursuit of safety, energy saving and high quality operation today.
