Four points of attention for instant electric water heater
Glass: this heat efficiency is very high, life expectancy is better than stainless steel, but there are also the same problem, the thermal efficiency will decline, can do water and electricity separation, security moderate.
Die casting aluminum: the most secure, because it is solid, the whole aluminum inside around the stainless steel pipe, water separation, so there is no scale, aluminum element is very stable, so that the use of more than 10 years have no problem, but also consider the life of other parts, integrated electrical quality to keep up. Consider the problem as a whole
Instant heating electric water heaters are now divided into several categories:Stainless steel: the shortest life, generally 2 years scrapped, five year long time, because it is easy to produce scale, thermal efficiency will decline rapidly, the power of the big easy to burst, a fever this is the old body, only low-cost manufacturers will do
1. without mixing valve. The water heater does not require the use of mixing valve, mixing valve for use if there will hit the middle of the cold and hot water while mixing flow, when water flow becomes small, leading to the water heater temperature is too high, over temperature (temperature control action), will appear the phenomenon sometimes hot and sometimes cold water staff should inform the customers using the mixing valve, direct power to the hot end, without mixing cold water, this will make the product has long service life and is not easy to fouling;2. control the flow of water. To install electric water heater must be equipped with special shower manufacturers, the water heater in the normal condition, can regulate the water flow or water temperature plus high bit upgrade. And the general users have no control tap traffic habits, resulting in the water does not reach the predetermined effect;
