The heating time of the solar electric water heater depends on the initial water temperature, the target temperature and the heating power used. In summer, if the water temperature rises from 20 degrees to 38 degrees, it takes about 6 to 7 minutes to rise one degree, while in winter, it may take 10 to 12 minutes to exceed 45 degrees. Taking 200 liters of water from 20 degrees to 70 degrees as an example, approximately 12.6 kilowatt hours of electricity are required. It takes approximately 8.4 hours to use a 1.5 kW electric heater, and only 5 hours with a 2.5 kW heater.
However, lower water temperatures in outdoor environments are also a factor. If water with a temperature of 70 degrees is exposed to 10 degrees indoors, it will cool down in about 20 minutes. In the water tank, a high-quality water tank can prevent the water temperature from dropping more than 5 degrees per day, whichwhich can effectively extend the water temperature maintaining time.
Safety and maintenance must be considered when using solar electric heating. For example, avoid filling water immediately after drying the water tank to avoid vacuum tube rupture. Check the auxiliary heat source and heat exchanger regularly to ensure that the leakage protection of the electric heating element is normal. Be sure to unplug the power supply when taking a bath, choose reliable quality products when using heating tape, and be careful when the voltage is unstable.
In general, the heating time of solar electric water heater should comprehensively consider many factors and follow the correct operation and maintenance guidelines to ensure the temperature stability of the water heater water and functionnormal operation of the equipment.
Tsinghua Sunshine Solar, when it rains, uses electric heating, and it takes 3 hours to heat up to 55 degrees. Is this normal? There is also a solar electric heater, does it consume a lot of electricity?
The solar electric heater is installed in the water tank on the roof.
The light on your electric heating socket means that your socket is charged. Just check whether the electric heater circuit plug is connected correctly, otherwise the electric heater may be broken.
Electric heating is very slow. The temperature only rises about 10 degrees in an hour. Are you too impatient?
An electric heater costs around tens of dollars. You can buy them anywhere solar water heaters are sold. It will take time and effort to get someone to replace it.
1: Normal! Indeed, the quThe amount of water you need to heat is relatively large. In addition to the water in the water tank, the water in the vacuum tube needs to be heated. If your water tank is around 150 L, then you need to heat it. approximately 250L of water.
2: The power consumption is indicated on the electric heater instructions and on the outer packaging, usually around 1200 W.
3: The holding time of 55 degrees at 42 degrees required for bath water must be more than 20 hours, unless it is extremely cold, below minus 20 degrees. If this duration is less than 20 hours, this means that your solar thermal insulation capacity is relatively low. Tsinghua Sunshine should be able to do it.
