Which water heater heating method is healthier?
1、Floating type immersion heaters (traditional type, standard type electric kettles)
Heating method: Watertank heating with float ball control. When the water is full and no water is drawn, the fast heat dissipation due to a single decorative cover and the absence of insulation causes a rapid drop in water temperature. The heating and insulation are achieved using a single high-power heating element, which is not energy-efficient.
2、Automated hot water dispenser (both standard and programmable)
Heating Method: Water tank heating, with probe control. Intermittent heating; when you remove some hot water, the water level drops to the control level, and cold water is added for heating. The initial boiling time should be 20-30 minutes; avoid wasting time by taking out hot water prematurely. Mechanical temperature control; this does not guarantee that all the water has boiled, and the water temperature is only about 88 degrees.
3、Instant hot water dispenser
Instant hot water heaters are those that dispense hot water immediately upon pressing a power button or turning on the faucet. They require a minimum power of 9kW, and their storage tanks are relatively small. High power allows for instant boiling of the water within the tank. The initial heating time is 6-10 seconds, and they continuously dispense hot water. When not in use, the hot water heater stops working, which makes it energy-efficient. The replacement rate of the heating element should be higher than that of other hot water heaters.
4、Boiling Water Heater (Conventional Boiling Heating Water Heater, commonly known as a boiling water pot)
Heating method: DC heating box with integrated water tank, probe-controlled. Multiple mechanical probes control the water level; after scale formation, the water level control may become unreliable. The initial boiling time is approximately 10-20 minutes.
5、Step-by-step water heating device (a new generation of water heating device utilizing step-by-step water heating technology)
Heating Method: Step-by-step, layered heating using 100% pure hot water. The divided container utilizes a step-by-step, layered heating technology. After dispensing, water can be added layer by layer and heated, providing continuous 100% pure hot water. Layer-by-layer boiling ensures complete separation of hot and cold water. Computer-controlled temperature ensures that the initial boiling time is 3-5 minutes. once the water boils, it can be dispensed and used immediately without waiting, saving time.
