How to choose a gas water heater

Winters are getting colder and colder now, especially in the south. It is very difficult to survive without heating in winter, and the snow is getting heavier. How can we do without a gas water heater in such a cold season? It is very convenient to use water with a water heater, especially in cold weather, when hot water is needed. Without a gas water heater, hot water cannot be supplied. However, many people are still laymen when purchasing gas water heaters and do not know how to choose a suitable one. Let’s take a look at how to choose a gas water heater.

Many homes have water heaters installed. However, when choosing, people don’t know much about water heaters, especially how to choose a gas water heater, and they don’t know what kind of water heater is suitable for their home. Here we will introduce the key points of purchasing a gas water heater.

1. The first thing to consider is the type of gas you will use. Each gas appliance has a label indicating the type of gas it is suitable for. Be sure to purchase products that use the same type of gas as you use in your home. At present, there are three main sources of gas in my country: natural gas, liquefied petroleum gas, and artificial coal gas. The design of the water heater is based on the characteristics of the gas source. Since the three gas sources have different compositions, the sizes of components such as burners designed and manufactured are also different. A water heater can generally only be used for one gas source. When choosing a gas water heater, customers should consult professionals and choose a water heater that is suitable for the gas source. Be aware of the signs: JSR for artificial gas, JSY for liquefied petroleum gas, and JST for natural gas to avoid making mistakes.

2. Users who use pipeline gas supply. When purchasing a gas water heater, you must ensure that the gas consumption of the gas water heater is not greater than the flow rate of the gas meter at home. Users who use cylinder liquefied petroleum gas should choose an appropriate pressure reducing valve, otherwise it will cause insufficient gas supply and cannot fully utilize the water heater's hot water supply capacity.

3. Carefully choose a cheap gas water heater. There are many gas water heaters on the market now, priced at eight or nine hundred yuan, or even lower. In fact, the burner, fan, gas valve, water valve, ignition system, control panel and the body itself would cost more than a thousand yuan if only ordinary quality materials were used. It seems that blindly pursuing cheapness is not a wise choice. At the same time, pay attention to purchasing products whose manufacturers have after-sales service in the local area.

4. When purchasing a gas water heater, consider whether the safety devices are complete. Reliable, such as flameout protection, water overpressure protection, anti-dry burning safety protection, anti-freeze protection, etc. It is recommended to choose a method with intelligent antifreeze function instead of the antifreeze method of manually draining water through the drain valve. In the past few years, many households’ gas water heaters did not have intelligent anti-freeze functions. The machines would freeze and leak if the water was not manually drained after taking a shower. In serious cases, the floor would be soaked, causing unnecessary losses.

5. The amount of water output per minute of the water heater varies. Therefore, water heaters are available in 6-liter, 8-liter, and 10-liter specifications. Large-flow water heaters are suitable for families with large populations and without heating, while small-flow water heaters are the opposite. If you live on a high floor above the fifth floor, it is best to choose a gas water heater that starts with low water pressure.

6. At least choose a forced exhaust gas water heater. The exhaust gas discharge method of ordinary flue gas water heaters has high installation requirements, and most residents do not install it according to the specifications. The flue of the forced exhaust gas water heater can easily meet the regulatory requirements. For easy operation, products with large backlit LCD windows and digital touch buttons are also good choices. In terms of internal configuration, the most advanced machines on the market now use electronic proportional valves to intelligently adjust combustion power, and are equipped with stepless frequency conversion strong blowers, which can maximize combustion efficiency and save gas. In order to achieve better constant temperature effects, high-precision electronic water temperature and water flow sensors and other devices are also important. The best quality heat exchangers on the market today are environmentally friendly oxygen-free copper heat exchangers, which have higher heat exchange efficiency and longer life. In terms of safety performance, which consumers are very concerned about, they should choose a full-process safety self-check system with a microcomputer. If the product can be equipped with a very delicate and compact digital wired remote control, and the operator on the machine can also be removed and installed in the bathroom as a wired remote control, it should be a masterpiece among forced exhaust products.

The above introduction on how to choose a gas water heater is very detailed. Now there are more and more water heaters on the market, which will lead consumers to make blind choices. When buying a water heater, you must refer to the above points to choose the most suitable one, especially one with good quality and reputation.
