Instant electric water heater and fast heating electric water heater are two important types of electric water heater. They are similar in appearance, but in fact they are quite different. When consumers choose, how to distinguish instant electric water heater from fast heating electric water heater? Now, I'll give you some tips.
Difference between instant electric water heater and fast heating electric water heater 1: heating principle
Instant electric water heater is a kind of water heater that can quickly heat the water through electronic heating components, and can control the water temperature, flow rate, power, etc. through the circuit, so that the water temperature can reach the temperature suitable for human body bathing.
In the high power state, the fast heating electric water heater uses a kind of heating body with strong thermal conductivity to convert electric energy into heat energy, which then transfers the heat to the water. The water can be heated rapidly by using the powerful heat.
The second difference between instant electric water heater and fast heating electric water heater: different power
In order to achieve the goal of fast heating speed, that is, the power of the thermal electric water heater is usually more than 5000W. However, the power is too large, and the requirements for the installation circuit are also very strict. It is difficult for ordinary family lines to bear the power of more than 7000W, and the safety problem is also a big hidden danger. This is also an important reason why the market share of instant electric water heater is still unable to compare with that of traditional water storage electric water heater.
The power of the fast heating electric water heater is mostly between 3000W and 5000W, and the installation condition is lower than that of the instant heating electric water heater. The user can install and use it without refitting the home meter and circuit wiring.
The difference between instant electric water heater and fast heating electric water heater is three: heating speed
The instant electric water heater can start heating in a few seconds, so it has the advantages of instant heating and no waiting.
The heating speed of the fast heating type electric water heater is slower than that of the instant heating type, which can not achieve the instant effect, so it needs to preheat about 15 minutes in advance.
