Instant type Intelligent thermostatic water heater Compared with the bucket type, the instant type does not always use full power for bathing every time. Take the instant type intelligent constant temperature water heater 8.8KW as an example. The power is adjusted according to the inlet water temperature or the size of the inlet water. Under the same large water yield, the first gear 880W is used in summer, the second gear 1760W or the third gear 2640W is used in spring and autumn, and the eighth gear 8800W is used in winter.
The manufacturer of the integrated smart thermostatic water heater of WanMite can give an example. The premise is that if you take a bath every day, the household electricity is 0.5 yuan/kilowatt hour, and the power consumption=power * duration. 60L storage water heater with a capacity of 2KW: preheat for 2 hours, and the power consumption is 2KW * 2h=4 kilowatt hours. However, since the thermal efficiency of the storage water heater is only about 80%, the power consumption will be a little more. Even if the low power consumption of the previous day is 4 kilowatt hours, the power charge is 2 yuan. Instant intelligent constant temperature water heater with actual power of 7KW and operating power of 6KW: it takes half an hour to take a bath every day, the thermal efficiency is up to 97% or more, the power consumption is 6KW * 0.5h=3 kilowatt hours, and the electricity charge is 1.5 yuan.
Take Spring and Autumn as an example. Instant intelligent constant temperature water heater, also taking 8800W as an example, uses 2640W power in spring and autumn, and consumes 2.64 kilowatt hours of electricity. According to the actual average bathing time, everyone takes about 10 minutes. Generally, the actual power consumption is 2.64/6=0.44 kilowatt hours; The 60L bucket type water heater needs to be heated for about 60 minutes in advance. The 60L bucket type water heater needs to keep warm while generating heat, which consumes about 10 minutes of electricity. The 60L bucket type water heater can only supply water for three people. Take 2500W as an example, so that each person is equivalent to 2.92 ° electricity/3=0.97 degrees. The power consumption of the bucket type water heater is more than twice that of the instant type water heater!
Take summer for example. Instant intelligent constant temperature water heater, also taking 8800W as an example, uses first gear power 880W in summer, consumes 0.88 kilowatt hours of electricity, and the actual average bathing time for each person is about 10 minutes, the actual power consumption is 0.88 °/6=0.147 kilowatt hours; The 60L bucket type water heater needs to be heated for about 30 minutes in advance. The 60L bucket type water heater needs to keep warm while generating heat, which consumes about 5 minutes of electricity. The 60L bucket type water heater can only supply water for 3 people. Take 2500W as an example, so that each person is equivalent to 1.45 ° electricity/3=0.47 degrees. The power consumption of the bucket type water heater is more than three times that of the instant type water heater!
