A few days ago, various places have entered the coldest period of winter. At this time, it is one of the most comfortable things to go home to take a hot bath every day, and a good water heater is particularly important. However, there are various kinds of water heater products on the market at present. Consumers often use "fog in the fog" when purchasing. It is not completely clear how to choose a suitable water heater except for the brand and price.
In this regard, experts in the industry have suggested that the core competition point of the gas water heater industry is "constant temperature technology", that is, the temperature can be kept constant during use, and consumers are encouraged to refer to two indicators when purchasing water heaters - temperature control Technology and energy saving effects.
The most annoying situation in bathing is that the water temperature is hot and cold. The current national regulations on the constant temperature standard for gas water heaters are: When the water pressure fluctuates, the fluctuation range of the outlet water temperature cannot exceed ±3 °C, and some international leading brands can This interval is controlled to be smaller. Take the well-known international brand, Linne, as an example, the microcomputer control system used to ensure that the water temperature is at most ±1 °C from the set temperature, and the human body barely notices the obvious difference.
In addition, the temperature control performance can also refer to the product's "water stop temperature rise" coefficient, especially when the water heater is turned off after 1~5 minutes, usually there will be a section of hot water above the set temperature. At present, the national water temperature rise standard set for gas water heater products is no more than 18 ° C, and the unique temperature memory function in the forest can control this inevitable phenomenon at 6 ° C, so that even if the user turns off the water heater briefly during use Re-opening will not be suddenly burned.
In the winter, everyone often wants to stop taking a hot bath. Gas and natural gas have been rising in price. While washing, they have to distress their bills. As a result, many water heater products are now starting to use energy-saving cards, such as Lin’s The first-class energy-efficient condensing water heater with international leading "double thermonuclear" technology. At present, the gas water heaters commonly found in Chinese households only have the "single core" technology, that is, there is only one heat exchanger. The large amount of high temperature flue gas generated during the combustion process is directly discharged from the flue without full utilization. The exhaust gas temperature is 110. ~160 °C or so, a lot of thermal energy is wasted, and the condensing water heater in the forest has two heat exchangers to fully absorb the heat generated by the burner, and can recycle the heat energy brought by the high temperature flue gas, the thermal efficiency is 15% higher than that of the ordinary water heater. ~23% or more (thermal efficiency is calculated according to the current national standard low calorific value), which belongs to the national first-class energy efficiency standard. In this way, the same amount of gas consumed during the same period of bathing, the natural cost is saved, and the economy is also in line with the present. Many "green families" living and consumption concepts.
