The heat exchangers (commonly known as water tanks) of all Nengli machines are made of efficient phosphorus deoxidized copper material. The new design of the thermal fins, the hole-shaped heat-cutting structure, and the fin bending treatment increase the heat exchange area, so that the high-temperature flue gas and the water flowing through the water coil can fully exchange heat, effectively improving the heating efficiency and having a long service life. Prevent freezing damage, oxidation, and corrosion! ! !
The core component of the gas water heater is the water tank. The material of the water tank is very important. Nengli is the only brand in China that uses phosphorus deoxidized copper water tanks for all its products. Everyone in the industry knows: first-rate water tanks use phosphorus-deoxidized copper (using the oxygen affinity of phosphorus to continue deoxidation on the basis of oxygen-free copper to form phosphorus-deoxidized copper, with a copper content of more than 99%), second-rate water tanks use oxygen-free copper (other brands High-end machines, after oxygen-free treatment, the copper content of oxygen-free copper reaches 99), the three-flow water tank uses lead-tin copper, and lead-tin electroplated copper contains lead-tin and other heavy metals that are not good for human health.
Characteristics of phosphorus deoxidized copper:
1. Fast thermal conductivity, high thermal efficiency, the maximum temperature can be set to 75 degrees.
2. High temperature resistance, corrosion resistance, service life of up to 15 years, far exceeding the national standard of 8 years.
3. The surface is smooth and not easy to scale, so no cleaning is required for life.
4. The advantage of one-time molding processing technology, no seams and no leakage.
5. Nengli water tanks all use 0.8 mm thick copper pipes, while other brands use 0.4 or 0.5 mm thick copper pipes. The weight of the water tanks is doubled. The weight of the whole machine is about 30 kilograms, and other brands are 20 kilograms. Domestic brand water tank heat exchangers have a 3-year warranty and a service life of 6-8 years. The Neng rate water tank heat exchanger has a 10-year warranty and a service life of up to 15 years.

Technical advantages
1. Fully enclosed combustion chamber
The combustion chambers of all Nengrate products adopt patented fully enclosed combustion technology. Domestic brands all use open combustion chambers, and the flame can be directly seen in the combustion chamber, which is a completely different technology. The energy efficiency is to use bottom blower technology to supply oxygen to the closed combustion chamber, while domestic air intake is all natural. There are several advantages of closed combustion: First, safety. Gas water heaters are most afraid of gas or exhaust gas leakage. With fully closed technology, the gas is burned in a closed combustion chamber, and the exhaust gas is directly discharged to the outdoors, fundamentally eliminating safety hazards. However, when domestic brands enter the air, exhaust gas and gas will be lost at the same time. When you use them, you will often smell exhaust gas, leaving potential safety hazards. This is why we can rate the industry to have zero safety incidents. Secondly, it saves energy. The heat generated by combustion is used to heat the water in the water tank, and the heat is well preserved.
2. Variable-frequency lower-mounted blower
All Nengli products adopt imported variable-frequency lower-mounted blower technology. Domestic brands still use the up-drawing blower technology that Nengli eliminated in 2000. It can fully ensure that all waste gas is discharged outdoors, and can intelligently adjust the speed to fully supply oxygen to the combustion chamber to ensure that the gas is fully burned to achieve the effect of energy and gas saving (equivalent to someone fanning under the stove). In an open combustion chamber, a lot of gas is drawn away and wasted without being burned, which is not energy efficient. The high-efficiency fan is designed to be in the low-temperature zone below the combustion chamber. It works stably. The continuous heating time is 60 minutes. It has a long service life and an extremely low failure rate. Domestic brand designs place the combustion chamber in a high-temperature zone and work unstable. They will automatically shut down after 20 minutes. The failure rate is very high.
3. Magnetic levitation moving coil proportional valve
All Nengli products adopt magnetic levitation moving coil proportional valves (the same principle as maglev trains), which can infinitely and accurately control the amount of gas required for combustion. The response speed is fast, the air pressure is controlled accurately, the double valve and three sections are accurately controlled, and the firepower is intelligently controlled according to the water temperature in different seasons to save gas.
Domestic brands currently use moving rod mechanical gas proportional valves, which can only simply control the large and small firepower, have slow response and short service life.
4. Water volume server
Equipped with the industry's most advanced water control device - water volume server, based on the set outlet hot water temperature, water pressure, air pressure and inlet water temperature. According to changing conditions, the inlet water flow rate is automatically adjusted to ensure a constant outlet water temperature. Together with the magnetic levitation gas proportional valve, it truly realizes dual regulation of water and air, so that you can get a comfortable and constant water temperature in all seasons.
5. Imported CPU computer board
Using imported 64-bit intelligent CPU, it can perform high-speed and precise calculations and quickly reach constant temperature. The CPU-guided electrical control system, which is comparable to aerospace technology, can sensitively sense the water and air volume, and reasonably adjust the air volume, gas volume and water output, quickly and accurately reach the user-set temperature, and always maintain a constant state, with automatic control throughout the system. Quick and stable. Domestic brands use traditional single-chip computer boards.

b , post-feedback + micro-adjustment (FB control)
The gas and water output are quickly adjusted after precise calculation by the CPU. The water temperature difference of the standard model for complex water use situations such as multiple faucets boiling water is ±1 degree (reaching the international standard of ±2 , far exceeding the national standard ±5, with a water volume servo of ±0.5 degrees, and the new product K2AAFE can achieve ±0.01 degrees. Domestic brands are designed, developed and produced in accordance with the national standard ±5)
2. Temperature rise when water is stopped.
Perfectly solves the problem of sudden heating and cooling after turning off and on again during use
Nengli’s unique Q skill technology, the CPU remembers the user’s usage habits and cooperates with the unique bypass pipe design to effectively control the shower The water temperature sandwich phenomenon occurs when the water flow is turned off and the temperature fluctuates violently. When water is stopped, the temperature rise is ≤1 degree, while the new product K2AAFE can achieve ±0.01 degree. Domestic brands are designed, developed and produced in accordance with the national standard of ±3 degrees. The temperature fluctuations are very large and the bathing experience is not good.
3. Low water pressure water flow startup
Neng rate adopts ultra-low water pressure and ultra-low water flow startup, which perfectly solves the problem of failure to start due to low water pressure during peak water use periods or high floors. The ultra-low operating water pressure is 9.8kPa, and the operating water flow is 2L. When the faucet is opened halfway, the hot water can be started with a thick flow of water using your finger. Domestic brands have an operating water pressure of 20kPa and an operating water flow of 5L.
4. Fast startup
It can ignite in 0.1 seconds per imported CPU, and the same pipe length can produce hot water more than 10 seconds faster than other brands.
5. Ultra-micro fire control
Large flow in winter, but the water is not hot in summer.
The temperature of ordinary models reaches a minimum of 35 degrees in summer, while the D series, K2 series, J series, H series, S1 series, and S2 series constant temperature water heaters adopt three-stage fire power and ultra-micro control to reduce flames. Precisely controlled, the lowest water temperature reaches a unique 32 degrees to meet the best effect of warm water bathing in summer. Unique four-in-one water volume control detection, equipped with water volume server, perfectly solves the problem of high-flow bathing in winter.
