Gas water heater As a commonly used electrical appliance in many people's homes, many people always pay attention to whether the gas water heater has a "zero cold water" function when purchasing. Zero cold water allows us to use hot water without waiting, which is very convenient. However, when we are buying a gas water heater, don’t just focus on “zero cold water”. These three functions are also very important. Let’s take you to learn more about it.
1. Want to be comfortable: Constant pressure
When we buy gas hot water, constant temperature and constant pressure are also very important. The constant temperature function can avoid the heating delay of the water heater. Currently, most water heaters can do it. However, constant pressure is not available in all water heaters. A water heater with constant pressure will not change the water pressure due to water use in other places. Therefore, there will be no problem of cold and hot, and it is very comfortable to use. Only when clearly states that it is a "constant temperature water servo water heater" can it be considered a constant pressure water heater.
2. Want to save energy: The smoke exhaust method of condensing
can be divided into three types: strong discharge, condensing and balanced. Among them, the condensing water heater will install a heat exchange device near the flue to allow the gas and tap water to meet here, transfer the heat to the water, and indirectly preheat it, which is more energy-saving than the other two water heaters, and can save a lot of gas costs in a year.
3. Want to be comfortable and energy-saving: the frequency conversion function of frequency conversion
air conditioner, and also has gas water heater. However, the "frequency conversion" on the water heater refers to the frequency of the fan. The water heater with the frequency conversion function can automatically identify various factors such as water temperature, room temperature, etc. through , and automatically change the fan frequency, which can achieve the purpose of precise temperature control, which is relatively more energy-saving and comfortable
