What are the differences between phosphorus and copper heat exchangers and stainless steel heat exchangers?

As the core part of the gas water heater, the heat exchanger is called the “heart” of the water heater. The hot water depends on it.

On the market, the gas water heater of different brands is also different. Types are generally divided into dehydrated copper heat exchangers and stainless steel heat exchangers.

Although both have good thermal conductivity, because their respective attributes are different, the effects are different when used as heat exchangers. What are the specific differences? Here we have made a very detailed summary for everyone.

1. Hot -conducting

The core function of the heat exchanger is to change heat. The faster the heat exchange speed, the better the quality of the heat exchange.

The heating coefficient of copper is 400W/mk, and the thermal conductivity is second only to silver. It is about 25 times that of 304 stainless steel (thermal conductivity 16.2W/mK).

Therefore, the dehydration copper heat exchange device is fast, the time used for hot water to become hot water, and the higher the overall efficiency of the water heater.

2. Bacterburbage

There are many impurities in the water, and many subtle bacteria are hidden. Stainless steel and copper can inhibit bacteria in water.

Stainless steel heat exchangers, smooth inner walls, bacteria are not easy to attach.

Copper ions can kill or inhibit bacteria in water, and scientific experiments from many world -class authoritative institutions such as EPA in the United States have proved that copper can kill more than 99.9%of bacteria within two hours.

Copper’s natural bacteriostatic effect is stronger than stainless steel.

Third, corrosion resistance

The living water of Chinese tap water plants is disinfected with chlorine gas, and the water is rich in chlorine ions. It is easy to corrode metal and rust.

The reason why stainless steel is in contact with water is not rusting because there is a layer of extremely thin and solid, stable chromium -enrich oxide film (protective membrane) on the surface. But if this film is destroyed, stainless steel will rust.

The oxygen content of deoxytic copper is very low, and it is not easy to react with chlorine ions in water at high temperatures. It is more corrosion -resistant and does not produce harmful substances. High safety.

Fourth, ductility

The heat exchanger has been in an environment with high temperature and low temperature crossing for a long time, and thermal expansion and contraction. Therefore, it is very tested to the extensibility of the material, and the degree of pressure can be refined.

The better the ductility, the longer the service life of the heat exchanger, the less likely to be damaged. Otherwise, long -term thermal expansion and contraction will easily make heat exchangers aging, cracks on the surface, and affect the service life.

Copper can be made into fine copper wires with very diameter diameter, which is very ductantly, has higher ductility of deoxidiated copper, and is not prone to hydrogen and brimmed phenomenon. The anti -heat impact is 100 times higher than stainless steel.

Five, raw material cost

The cost of high -quality off -the -line copper and stainless steel is also much more expensive than stainless steel. When the source material is selected from the Telville gas water heater, the cost of deoxymal copper used is 3.6 times that of the same quality stainless steel.

Overall, the heating speed, thermal insulation effect, and the environment of the deoxymal heat exchanger are better than the stainless steel thermal switch.

Nowadays, there is a phosphorus dehydration copper heat switch, which has stronger thermal conductivity and higher ductility. It is called the burning heat switch.

At present, the brands that use phosphorus deoxytone hot exchanges in the industry are mostly joint venture brands, such as Teville, forestry, and energy rates.

Teville is a German high -end heat -burning brand. It is currently mainly pushed the CRS high -end series in the Chinese market. It uses German heat combustion technology and 40%of its original imported materials. Luxury lineups are configured such as phosphorus deoxy copper heat exchangers, water server, gas ratio valve, and gas ratio valve, and gas ratio valve, gas ratio valve, and gas ratio valve, gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve, and gas ratio valve. Poor brushless mute fans.

The super configuration creates the powerful performance of the Tevil gas water heater. High wind resistance, ± 0.5 ℃ intelligent constant temperature, less than 45 decibels of static operation, 3 seconds of pipeline speed, etc., not only bring convenient and comfortable constant temperature hot water to consumers , Also greatly improved energy use, water saving solar terms, environmental protection and efficiency.
