A 2 kilowatt electrical appliance consumes 2 kilowatt hours of electricity for one hour of operation. However, the water heater does not boil water all day. When the boiling water temperature reaches the desired temperature, it is triggered. and stop heating water and stop using electricity. If it is not used to heat water all the time, the water heater basically does not need to boil water and use electricity that day, but if the newly boiled water is completely used up. once, the water heater will need to boil the water again to reach the set temperature.
In addition, the specific power consumption depends on the capacity of the water heater, generally around 30 to 40 liters, or around 1,500 to 2,000 W.
In others terms, 1.5 to 2 kWh of electricity are consumed for 1 hour of work. Of course, this also depends on the frequency of use. The tAmbient temperature will also affect power consumption. Generally, daily electricity consumption is between 2 and 3 degrees, and in winter, between 3 and 5 degrees.
If the frequency of use is not high and you only use hot water for bathing, you can turn on the electricity to heat it before using it in summer. It can be heated for about 15 minutes to meet bathing requirements. This is the most energy efficient use and the energy consumption is about 0.4 degrees.
The difference between Haier 2000 watt and 3000 watt electric water heaters
Approximately 250 cubic meters. A three-phase electric water pump with a power of at least 3,500 watts is needed to produce 400 cubic meters of water per hour. Because under normal circumstances, our 2000 watt water pump can only produce about 250 cubic meters of water per hour. In order to achieve ahourly water flow of 400 cubic meters, a high-power three-phase electric water pump should be used. At the same time, the pipe diameter is not suitable. Only pumping pipes less than 20 cm can achieve this goal.
The differences between Haier 2000 watt and 3000 watt electric water heaters are as follows.
1. The power of both is different
(1) The power of Haier 2000 watt electric water heater is 2000 watts
(2) Haier; electric water heater 3000 The power of one watt is 3000 watts;
2. The power consumption of the two is different
(1) The power consumption of a 2000 watt Haier water; heating in one hour is 2,000 W·h, or 2 degrees of electricity.
(2) The power consumption of a 3,000 watt Haier water heater in one hour is 3,000 W·h, or 3 kilowatt hours of electricity.
3. The heating rates of the two are different
Forwater heaters of the same volume, the heating rate of a 3000 watt water heater is higher than that of a 2000 watt water heater. water heater in watts.
Detailed information:
1. The formula for calculating electricity (electrical energy) is as follows. W= P*t, the unit of electrical energy is the kilowatt hour (kW·h).
Where W represents electrical energy, P represents active power in kW and t represents time in hours.
2. Units of electrical energy include joules, kilojoules, degrees, kilowatt hours and watts per second.
3. Conversion between units of electrical energy
1 joule = 1 watt × second, 1 kilojoule = 1,000 joules, 1 degree =1 kilowatt hour,
1 kilowatt hour = 1 kilowatt × 1 hour = 1,000 watts × 1 hour = 1,000 watts × 3,600 seconds = 3,600,000 joules = 3,600 kilojoules.
