Sanyou Electric will answer your question: "There are two types of electric boilers. The resistance/electromagnetic heating principles are different, the safety performance is different, and the prices are also different, ranging from a few hundreds to 3,000, etc.,
Comparison between electromagnetic heating furnace and resistance heating furnace
Electromagnetic heating furnace:
1. Electromagnetic induction heating, real water and electricity separation, circuit and waterway isolation
2. Low-voltage soft start reduces the risk of power surges and avoids damage to equipment due to power fluctuations Voltage
? Part of frequency power output can be used Automatically adjust the current according to voltage fluctuations to ensure constant power and will not cause damage due to insufficient electrical load.ante due to the increase in heating furnace voltage:
? p>
? 1. Resistive heating, whether the resistance material is inside or outside, is carried out through the heat-conducting medium. This is not a true separation of water and electricity. There is a hidden risk of leakage. to corrosion or breakdown of the medium.
? 2. The relay directly powers the resistance rod, and the impact current is large, which is prone to overcurrent and voltage fluctuations, and may also cause damage. to other electrical appliances.
? Structural design
? Electromagnetic heating furnace: the water channel and circuit of the whole machine are separated, the structure is reasonable, and the safety is high < /p>
? Resistance heating furnace: Water and electricity are not separated throughout the machine, which is a big safety risk
? Energy saving
p>? heating oven:
? High-frequency electromagnetic induction heating directly acts on the water bladder through electromagnetic induction, causing the water bladder itself to heat up, thereby reducing the process of medium conduction heat loss. Lower and higher thermal efficiency. , instant heating, no need for heat storage container, instant thermal efficiency can reach more than 98%, more than 30% energy saving compared with resistance heating furnace type:
?? 1. Resistive heating, which conducts heat to the water tank through the heat-conducting medium, resulting in significant heat loss
2. Local heating is easy to produce scale and affects the thermal conduction 3. Some materials Severe attenuation, resulting in low thermal efficiency? Lifespan
? usedfor over 15 years
? Resistance heating furnace: The resistance wire is easy to age and has a short service life, generally 3-5 years. Electromagnetic heating furnace: The frequency of heating power is 20,000 Hz, which exceeds the normal hearing of the human body. This not only improves thermal efficiency, is quiet and environmentally friendly
? There is a “buzzing” electrical frequency noise when the power supply is operating. When the surface water temperature is high, there will be bubbles producing the sound of boiling water < /p>
?? Electromagnetic heating furnace: electromagnetic induction heating. During operation, the heating core component is a fixed magnetic field after passing through, and the water structure is magnetized.
? Resistance heating furnace: The resistance wire is usually replaced tous every 3 to 5 years, and as it produces tartar, it must be descaled regularly.
