Electric water heater, water storage or instant heating is better, and safe?
The water storage type water heater is usually 1000 watts or more, and a lot more is about 2000 watts. That is, the hot water heater power is so high, is not the voltage requirements of the wire is also very high? In fact, 6500 watts to 7500 watts, that is, hot water heaters require 4 square lines, and 8500 watts for 6 square lines, the current market in 2005 after the house is basically equipped with 4 square lines. If it is 5500 watt kitchen Po that is only 2.5 square line, basically all the family line meet this requirement. The storage water heater also only needs 2.5 square lines. In terms of voltage requirements, the power is not high, the voltage must be high, power = voltage * current, that is, the hot type is also used 220 volts.
Storage of water, then, the better sales of the three brands are Haier, Smith and Aston, of which Haier occupies 40% of China's market share, but with electricity prevention is more authoritative is the anti - electric wall technology
Instant heating may be better, less electricity, but when hot work, the voltage is very high, safety is the most important, there is only a Haier that is hot, and with electric walls, can avoid safety problems. There is no absolute authority against leakage that is hot electric water heater, it is best not to buy, bathing safety problem is not a small problem, the probability of occurrence can only be 0, or else do not buy.
