Generally, in summer, the hot water temperature reaches 38 degrees, and it takes about 6 or 7 minutes to rise one degree. In winter, the hot water temperature reaches over 45 degrees, and it takes about 6-7 minutes. 10-12 minutes to go up one degree.
The electrical heat per kilowatt hour is 860 K and the conversion rate is 92%. If 200 liters of water goes from 20 degrees to 70 degrees and the temperature increases by 50 degrees, the required power consumption is 200. *50/(860*92%) = 12.6 degrees. Electricity, using a 1.5 kW electric heater requires time: 12.6/1.5 = 8.4 hours.
It takes an electric heating time of 2.5 kW: 12.6/2.5 = 5 hours. If 70 degree water is exposed indoors at 10 degrees, it will become cold in about 20 minutes if in a water tank. , the temperature of a good water tank will not drop more than 10 degrees 24 hours a day, and the bestTheir water tank will not drop more than 5 degrees.

Notes:
1. In severe winter, if there is no water in the water tank, the water should not be filled immediately after air drying. Since the temperature inside the vacuum tube can reach about 2500°C when air-drying, the water in the water tank. The water tank should be filled before sunrise or halfway. Do this after an hour to avoid pipe explosion.
2. If an auxiliary heat source is installed, the auxiliary heat source device and heat exchanger should be checked regularly to see if they are functioning properly. For auxiliary heat sources heated by electric heating pipes, you must ensure that the leakage protection device works reliably before use, sotherwise it cannot be used. When using the electric auxiliary heater, special attention should be paid to filling the water. The volume of water in the water tank should not be less than 50% to avoid dry burning without water.
3. When taking a bath, pay particular attention to unplugging the power plug, and it is strictly prohibited to use it when the power is on.
4. When installing heating tapes, be sure to choose products of acceptable quality to ensure normal use and reduce hidden dangers. When using the heating tape, be sure to turn it off promptly after defrosting, and try not to use it when the voltage is unstable.
