Does The Shower Set Need A Good Heater?

The principle of constant temperature shower is not difficult to understand. Everything is realized by constant temperature valve core. There are two mainstream valve core materials, one is paraffin valve core and the other is nickel titanium alloy. The two kinds of valve cores are: through the volume change of the valve core after encountering heat, the inlet and outlet proportion of cold and hot water is changed, so as to achieve constant temperature. This determines that its control performance is affected by external input conditions. When external conditions fluctuate, its control output, that is, the temperature after mixing water, will fluctuate, not constant, and its control performance has a certain lag. Therefore, the constant temperature valve core, that is, the constant temperature shower, if you want to have high temperature control accuracy and avoid sudden cold and heat, the external conditions must be relatively stable. And the closer the actual working conditions are to the original design working conditions of these valve cores, the higher the control accuracy of constant temperature shower.

There are many types of water heaters: electric water heater (also divided into water storage type, i.e. hot type), gas water heater, air energy water heater and solar water heater. Among these water heaters, except the solar water heater, which cannot use the constant temperature shower because of its inherent insufficient conditions, other water heaters can use the constant temperature shower. Even the hot water heater is not recommended.

What is the relationship between constant temperature shower and constant temperature water heater? If you have been using water alone in your home, and the water pressure in your home is very stable. In fact, thermostatic water heater is enough. Thermostatic shower is superfluous. From beginning to end, The water from the water heater goes to your faucet (shower) all have the same temperature. Then why do we need a constant temperature shower? We use the simplest words to explain: when two people suddenly use water at home, a diversion of water flow is formed. When the water flow becomes smaller, the temperature detector of the water heater will detect it and reduce the temperature to ensure the stability of the temperature. However, the waste heat of the water tank and water pipe will continue to supply water at this time Heat up. In fact, the temperature can’t be lowered instantly. Human beings don’t have such magical technology.

In that very short time, if you don’t have a constant temperature shower to adjust the temperature of the shower outlet, the water temperature will rise suddenly when you take a bath. Scald, in a moment. The instability of water pressure also comes from the water supply of the house. Although the thermostatic water heater tries its best to control the water outlet temperature of the water heater, it may also cause the water temperature to rise and fall. It’s not a long time, but it’s also very dangerous for a short time. This is why non constant temperature showers are gradually eliminated.

The valve core components of constant temperature shower are very sensitive and even fragile. Excessive temperature will cause irreversible damage to him. That’s why water heaters with smaller water volumes (water heaters lower than 13L) the reason why the constant temperature shower cannot be used is that the water flow is small, and the temperature of single hot water must be high to ensure sufficient water pressure. To put it simply, the water volume is small, and more water needs to be produced, just hot water and more cold water. The temperature itself is very high, and it is impossible to achieve 100% temperature control throughout the year: heat / solar energy. It is very easy Damage the thermostatic valve element. Therefore, major manufacturers do not recommend it.

In short, or a word: if you want to take a good bath, thermostatic shower thermostatic water heater is indispensable.
