Electric water heater
The water temperature and flow rate are the most stable, and are not affected by water ingress at all. It is controlled by the timing switch, the water needs to be heated in advance, and it is the first choice for household bathing.
Gas water heater
The advantage is that it is hot immediately, and hot water can be used at any time, but the temperature and flow of the effluent are greatly affected by the state of the water, and the water is not stable. Divided into two types of natural gas and liquefied gas.
solar water heaters
It is not suitable for urban life that requires hot water for 24 hours, or can only be used as a supplement to hot water sources, but the price is not cheap. If there is only one water heater installed at home, it is not recommended to choose a solar water heater.
Water heater volume
Gas water heaters can be used in the kitchen, with a capacity of 5 ~ 10L; bathing for 1 ~ 2 people is suitable for 40 ~ 5-L electric water heaters, 3 people is suitable for 80 ~ 100L; more than 3 people are suitable for about 120L.
The unit is watts (W), which refers to the power of the electric heating tube in the water heater. The larger the power, the faster the heating time. When selecting the power, it needs to be determined based on the cross-section of the meter and the power line with the actual clock.
The maximum temperature of the water tank of the water storage type electric water heater is generally 75 ° C, and 65 ° C is the heat preservation heating value. The most suitable water temperature for bathing in winter is about 37 ℃ ~ 42 ℃.
Refers to the normal power of this water heater when it is powered on. The power consumption of rated power of 1500W per hour is 1.5 degrees.
Power wall technology
Using the relationship between physical voltage and resistance, by extending the water channel, and then extending the role of water resistance, the voltage is unchanged, and the current is the principle of reduction. Even if the water in the water heater is charged, it can ensure the safety of people's bathing.
Anti-dry burn protection
In the state of water shortage of the water heater, in order to prevent temperature control from malfunctioning or dry burning under water shortage, a bimetal mechanical switch or electronic switch is used as protection, and its temperature control point is slightly higher than the boiling point of water.
IPX4 splash proof
IPX4 is a waterproof grade. The basic situation is that it can be splash-proof in use, preventing water from splashing in all directions from entering the appliance and causing damage.
