Kekr | Midea's gas water heater innovates the "tailless" technology, leading the industry into a new stage of first-class energy efficiency.
Recently, the 29th Midea Group Technology Month was inaugurated at the Midea Global Innovation Center in Foshan. As an annual event known as the "Midea Scientific Research Oscar", this Technology Month focuses on innovation, global localization, and transformation as its themes, with breakthrough excellent achievements in basic common technologies, key core technologies, and diverse industries making their appearances. At the scene, the Midea Kitchen and Heating R & D team showcased the latest first-class energy-efficient gas water heater without cold sensation. On the basis of solving the "water temperature fluctuation" problem caused by external interference during the water use process, the innovative "tailless" technology was developed, successfully solving the condensate water discharge problem of the first-class energy-efficient gas water heater, becoming the focus of heated discussion in the technology circle.

For many years, Midea has been deeply cultivating in the field of gas water heaters, continuously solving industry technical problems and leading the innovation and iteration of gas water heaters, from constant temperature bathing to silent noise reduction and then to high efficiency and energy saving. Its innovative first-class energy-efficient gas water heater without cold sensation adopts the anti-interference constant temperature system of no cold sensation 371, which can solve the problem of the water temperature suddenly becoming hot and cold in the domestic bathing water use, and solve the water temperature fluctuation problem in multiple interference scenarios such as turning off the water and turning it on again during the bathing process, using water in multiple places in the home at the same time, and the peak water use in the community in the morning and evening, truly achieving zero fluctuation in starting and stopping, and a "no cold sensation" bathing experience, bringing a new constant temperature bathing experience.

High energy consumption and condensate water discharge problems, the industry urgently needs to be solved
However, with the proposal of the national dual-carbon strategy, the home appliance industry is also actively promoting the green and low-carbon transformation and upgrading. Under the advocacy of the low-carbon and energy-saving life concept, people pay more attention to the energy efficiency level of home appliances. The energy consumption index of gas water heaters has always been one of the references that users value. It is not only related to energy saving, carbon reduction, and ecological environmental protection, but also related to the daily expenses of users.
At present, the market share of first-class energy-efficient products in the gas water heater market is only 7.4%. The reason is that on the one hand, there are only a few manufacturers in the market that can meet the first-class energy efficiency standard; on the other hand, the heat utilization of the first-class energy-efficient gas water heater will produce a large amount of condensate water, which is acidic. If it is discharged into the bathing water, it is not conducive to human health. If it is discharged, users need to drill additional holes and add a drainage pipe for installation, and then connect an external condensate water box, which not only affects the aesthetics, but also is inconvenient for frequent water pouring, and sometimes even encounters the problem of dripping water.
And Midea's gas water heater product line is mainly concentrated in the second-class energy efficiency. The products of the second-class energy efficiency have higher energy consumption compared to the first-class energy efficiency. This is because during the heating process of the gas water heater, the gas heat when the exhaust gas is discharged can reach 200°C, and this part of the heat energy is often wasted. This situation also prompts the Midea Kitchen and Heating R & D team to think deeply about how to completely solve the condensate water discharge problem and achieve a new technological breakthrough while improving the thermal efficiency.

Innovative "tailless" technology, leading the industry into a new era of first-class energy efficiency
Midea Kitchen and Heating, with a deep understanding of the industry pain points and user needs, and relying on its profound technical accumulation in the water heater field, innovatively launched the tailless first-class energy-efficient gas water heater without cold sensation, equipped with a new no cold sensation system. By predicting the changes in working conditions and making advanced adjustments, it effectively solves the pain point of "water temperature fluctuation". At the same time, it innovatively developed the "tailless" technology, which can fully utilize the heat energy by preheating a cold water through the secondary utilization of heat energy, thereby significantly improving the thermal efficiency and reaching the first-class energy efficiency standard. According to the "Energy Efficiency Limits and Energy Efficiency Grades of Domestic Gas Instantaneous Water Heaters and Gas Heating and Hot Water Combi-Boilers" GB 20665 - 2015 standard, the thermal efficiency range of the second-class energy efficiency is 88% - 90%; the thermal efficiency range of the first-class energy efficiency is 96% - 98%. And the thermal efficiency of Midea's tailless first-class energy-efficient gas water heater without cold sensation is as high as 104%. Compared with the second-class energy efficiency products, it can save 144.5m³ of gas per year, and the cost savings are 491.4 yuan. The total cost savings in 10 years are as high as 4914 yuan. For users who are careful with their expenses, it not only saves a significant amount of expenditure for users, but also is more low-carbon and environmentally friendly. At the same time, Midea's tailless technology also solves the problem of condensate water discharge. It pioneered the long-lasting purification material and is equipped with a unique condensate water purification control system to recycle and purify the condensate water for reuse, so that the water heater does not need to install a drainage pipe, and the condensate water can be directly and safely mixed into the bathing water, better saving water resources. This technological innovation not only marks that Midea is the first manufacturer in the industry to achieve first-class energy efficiency without condensate water discharge, but also is the only one to solve the problem of condensate water discharge of the first-class energy efficiency gas water heater, truly promoting the industry to shift from the second-class energy efficiency to the first-class energy efficiency, and leading the industry into a new stage of comprehensive first-class energy efficiency.

According to the data from AVC, Midea's COLMO AVANT Extreme Series gas water heater CTE816 single product won the TOP1 of the offline first-class energy efficiency products, promoting the gas water heater market to embrace a high growth. In the first half of 2024, the overall domestic sales scale of gas water heaters increased by 56% year-on-year, with the fastest growth rate in the industry, becoming the fastest-growing category in the kitchen and heating industry.

Looking forward to the future, although the tailless technology 1.0 has realized the recycling, purification and reuse of condensate water, eliminating the trouble of users installing drainage pipes, considering the need for long-lasting filter elements and recovery pumps, not only the technical cost is relatively high, but also the filter element is a consumable material that needs to be replaced regularly, there are still some shortcomings. In response to these two new problems, Midea is now actively developing the tailless 2.0 technology, striving to achieve no need to replace parts for a lifetime, while reducing the cost for users to purchase the tailless first-class energy-efficient gas water heater without cold sensation, allowing users to spend less money and enjoy the intelligent, convenient, green and low-carbon beautiful life brought by innovative technology.
As a global leading technology group, Midea always adheres to the strategic main axis of "technology leadership", and through technological innovation breakthroughs, continuously brings users a smart and beautiful life, and promotes the continuous innovation and evolution of the home appliance industry. This time, the Midea Technology Month showcases Midea's technological breakthrough and innovation achievements as well as the progress of the new stage of technology research and development, not only guiding the direction for the technological innovation of the industry, but also boosting the high-quality innovative development of the industry.
