Single and double tubes refer to heaters. One heater is called a single tube heater, and two heaters are called double tube heaters. Dual-tube power, fast heating, the other are the same. It's like using an induction cooker with only a few notches.

Single tube heating simply means that the electric water heater has only one pipe loop. The general power is 1500W and 2000 W. In short, the electric water heater has two pipes, and its power is generally over 3000W. Double tube heating has many choices, single tube heating or double tube heating. In general, the power of the upper heating tube is less than that of the lower heating tube.

Single or double water heater

Double tubes, because the two tubes have two heating tubes, heating speed is much faster. But the power consumption is actually the same, a 1000-watt tube heated for 1 hour, 2000-watt double tube for half an hour, the total power consumption is still unchanged, but the boiling water or related speed force, 2000-watt single tube will not be 2*1000 watts than the double tube. Generally speaking, it is faster to choose two tubes. If you have a single tube of 2,000 watts, you can have two tubes of 2,000*2. This should depend on the way you use and the electric environment you use, and keep heating slowly with a single tube of low power electric heating, which is relatively simple for the control circuit of the electric water heater, low failure rate, relatively small impact on the grid; double tube heating, to achieve half tank heating. Hot water is used for rapid heating with high power, high demand for power grid, complex control and high failure rate.

There is little difference. Some people say that double tube heating speed is fast, but the fact is the same. The efficiency of 500W + 500W double tube heating tube is the same as that of 1000W single tube heating tube.

Electric heat storage refers to the storage of water in a water tank after being heated by electricity. Double-tube heating refers to double-tube heating, which makes heating faster. Some electric water heaters have the functions of half-tank heating and full-tank heating, which can be adjusted according to needs. Hot water produced by stratified heating is faster and heated by double tubes more uniformly, all of which belong to electric heating. Double tube heating is used in many markets.

Buying electric water heater mainly depends on the courage inside, the other good, bad inside, basically scrapped. Generally stainless steel and enamel. Secondly, it depends on the service and warranty period. If there are any problems in the future, try to find a remedy. Single and double tubes refer to heaters. One heater is called a single tube heater, and two heaters are called double tube heaters. Dual-tube power, fast heating, the other are the same. It's like using an induction cooker with only a few notches.
