Abstract: With the improvement of people's living standards, users are highly concerned about bathing "healthy water quality" and "noise". At the same time, with the gradual maturity of drinking water treatment technologies such as impurity removal, sterilization, and disinfection, gas water heater companies have launched various selling points of health water heater products, but there are currently no corresponding standards to regulate their health performance in China. Although users know the importance of bathing water, there is no unified standard and quantifiable grade index to help them judge and purchase. Therefore, it is very necessary to establish a reasonable health performance evaluation method and classification standard to regulate the health water heater products on the market. By comprehensively combing, summarizing and categorizing various health technologies in the gas water heater industry, a number of health function indicators have been formulated, and the health functions of water heaters have been divided into 3 levels according to the user's health demand level, technical realization difficulty and investment cost. At the same time, according to the achievement of health function indicators, the health performance of Domestic Gas Instantaneous Water Heater and Gas-fired Heating Hot Water Combi-Boilers is objectively evaluated by dividing the health performance levels. On the one hand, it can ensure the health of users in bathing, and on the other hand, it can guide the development direction of health technology in the industry, which is conducive to the upgrading of products.
