Why doesn't the electric water heater run out of hot water for a while?
Turn off the power you think is without electricity, but it still consumes electric energy used in front of you, because the temperature of hot water in barrel residual energy continues to decline, release, or to re open the electricity to supplement, and open the difference and did not imagine so much, and the use of comfort is not big the same, the advantages and disadvantages of themselves, of course, the problem is still a level of consumption, always make others with open with the use of electric water heater is an old concept of low consumption level, as early advocate of refrigerator on closing the open pediatric method of the same.
Electric water heater is powered on for a long time, the central water heater temperature sensor in the water heater, heating to warm water, just the upper part of the water heater only the set temperature, the temperature lower is not hot, to the upper and lower temperature and heating again, so repeated several times, the whole cylinder can heat water, (this process is automatic, as the use of the refrigerator for the same reason) the effective volume of water heater can be fully utilized, so the electric water heater is not as open with the use, but 24 hours open, of course, it must use a little more electricity to heat insulation from offset,...... Rather, it brings to us is a comfortable life, the use of foreign electric water heater is very popular, it is the use of comfort and reaction speed than the gas water heater, oxygen consumption, environmental protection is relatively good, no switching power supply that there is a great relationship and people's consumption level and consumption concept.
Generally not without hot water, when you close the water out of the time, is the wall of the iron pipe cooling into cold water, put in and put out hot water
