First, let me share some shopping points with you: 1. Confirm the gas source There are two types of gas water heater OEM: natural gas and liquefied gas. Be careful not to buy the wrong one, or you won't be able to install it. Natural gas is transported by pipeline. Liquefied petroleum gas is canned. 2. Liter selection The number of liters of gas water heater has nothing to do with the capacity. Liters refers to the amount of water that can be produced per minute when the temperature difference between the tap water temperature and the set temperature is 25 degrees. Hot water quantity. At present, the number of liters of gas water heaters is mainly 10L, 11L, 12L, 13L, 14L and 16L (there are 20L and 24L, and families rarely choose). Use of a kitchen and a bathroom: 10 liters for southern users and 12 liters for users with high hot water needs;

12L is recommended for northern users. One kitchen and two bathrooms: 14 liters enough for southern users, 16 liters enough for users with high hot water needs; 16L is recommended for northern users. These are just a few suggestions. The specific choice can be chosen according to your own water habits. In addition, you must also consider the flow rate of the shower, such as the shower per minute in your home. The clock flow is 13L. If you choose the 10-liter model, there will be problems in use. This also needs to be taken into account. 3. Selection of water tank materials At present, whether it is a high-end brand or a low-end brand, most gas water heater water tanks are made of oxygen-free copper. But there are exceptions Smith gas water heater is a stainless steel tank. At present, the oxygen-free copper technology is mature, and the stainless steel water tank is not very good. Ordinary and new. When choosing, whether it is stainless steel or oxygen-free copper, you can decide for yourself. ---- gas water heater manufacturers
