How does the Haier electric water heater perform, and is it user-friendly? Here's a detailed overview from our editor: 1. Heating Time: It takes more than an hour to heat the water to 75°C. This is completely normal, especially during the first use, as the initial water is at room temperature. The heater typically operates at 2000 watts by default. For instance, if the current water temperature is 30°C, heating it up to 75°C requires a temperature increase of 45°C. At 2000 watts, this usually takes around 1.5 hours. However, after the first use, if there is already hot water in the tank, the heating time is generally shorter, often less than an hour. 2. Night Electricity Mode: If you have a time-of-use electricity meter, this feature can be very useful. First, make sure the clock is correctly set, then choose your desired temperature. Once set, the water heater will automatically turn on at midnight and shut off at 6 AM. A water temperature of 45°C may be due to the "mediator" function, which keeps the water warm once it reaches that temperature. This mode is highly energy-efficient because the temperature difference between 45°C and the ambient temperature is small, resulting in minimal heat loss. Compared to heating to 75°C, it saves more energy. 3. Insulation Performance: This is completely normal. When the ambient temperature is around 33°C, the water heater loses about 1°C every 1.5 hours. In winter, the temperature drops faster—about 1°C per hour. In summer, when heated to 75°C, the water can stay hot for about three days before returning to room temperature. In winter, it may take over a day to cool down. This level of insulation is quite good, as Haier uses a three-layer construction with foam insulation in the middle, ensuring better heat retention. Other brands may result in frozen water in the tank overnight during winter. 4. Energy Saving Tips: Leaving the water heater plugged in 24/7 is the least energy-efficient option. To save power, use the mediator function, which maintains the water at 45°C without needing constant heating. Since the temperature difference is small, the water cools down very slowly—usually no more than 2°C within two minutes. This is sufficient for a few people in winter, and you can also switch to 3D dynamic heating for instant hot water. With this mode, you can start and shower as soon as the water reaches 28°C. You can even boost it to 75°C and then switch back to 3D heating, allowing you to produce 320 liters of hot water from just 80 liters. Related Reading What’s the price of Deli shower rooms?
