First, how to choose zero cold water heater
1, look at the sign. As a shrewd consumer, you must choose a reliable brand when choosing a water heater. First, because of the installation of water heaters, big brands generally have masters who specialize in home installation. Professional masters can better understand the characteristics of products, skillfully install products, and avoid installation mistakes, leading to problems and accidents in the later stage. Secondly, because the quality of big brand products is more guaranteed and the after-sales service is more perfect, when the products have problems, they can provide free on-site service. 、
2. Look at the type. Water heaters are divided into artificial gas, liquefied petroleum gas and natural gas according to the characteristics of gas, and each category has a detailed classification. Therefore, consumers should choose the same type of water heater as the actual gas when buying water heaters, otherwise it will cause abnormal combustion of water heaters, burn out water heaters and endanger life safety. Generally speaking, brand-name water heaters are marked with strict gas types (for example, artificial gas has 5R, 6R and 7R; Natural gas includes 10T, 12T, 13T, etc. ), and consumers can find gas category labels on the outer packaging and shell when purchasing.
3, look at the number of liters. The mainstream gas water heaters in the market mainly range from 10-20 liters. The liter of gas water heater indicates the amount of hot water discharged within 1 minute when the temperature rises to 25C (the water output will change with the set temperature and water temperature difference). Generally speaking, it is more comfortable to wash with a large amount of water. With a large family population, large housing area and many bathrooms, it is recommended to choose a water heater with a water output of more than 16 liters; The family has a small population and only one bathroom. It is recommended to choose a gas water heater with a water output of 12- 13 liters.
4. Look at the safety device. Generally speaking, brand gas water heaters include: anti-burning safety device, anti-overheating safety device, anti-high pressure safety device, flameout protection device, anti-freezing safety device and water cut-off protection device. Microcomputer-controlled water heaters also have overload protection, smoke pipe blockage protection and excessive air flow protection devices. At the same time, when a fault occurs, there is an obvious fault display or alarm.
