How to choose the water heater in autumn and winter

The weather turned cold and went to the peak of water heater purchase. In addition to the seasonal demand, as a large-scale home appliance, the replacement of water heaters is slow, and many households may purchase it for several years, so it is necessary to do it before purchasing. With homework, you can buy products that are truly comfortable and suitable. I also hope that everyone can enjoy a comfortable and warm hot bath during work.

As we all know, the most common water heaters in the stores are electric water heaters and gas water heaters. The advantages and disadvantages of the two are very obvious. Gas water heaters can be used immediately to save time, but after collecting water, electricity and gas in one, for Product safety performance also puts forward new requirements. Electric water heaters are easy to install, but heating requires waiting. How to proceed according to the actual situation, choose the right water heater, the author today for everyone to cram.

Although the gas water heater is fast heating, has a large amount of water, less scale, and occupies a small area, it is not subject to the control of the amount of water, but the disadvantages are also many. The first concern is carbon monoxide poisoning. Gas water heaters need to emit large amounts of exhaust gas when they are used, including carbon dioxide and carbon monoxide that is not fully burned. At present, the safest gas water heater on the market is a strong exhaust type, and the exhaust gas is forced to discharge to the outside through the fan. Even if the windy weather occurs in winter, there is no need to worry about it.

Electric water heater can adapt to any weather changes, ordinary families can be installed directly, long-term power can be a large flow of hot water supply. When used, it does not produce exhaust gas. It is safe and hygienic. Most of the electric water heaters on the market today are equipped with electric shock protection devices, so there is no need to worry about safety.

Gas water heaters are suitable for families seeking for bath comfort and efficiency, while electric water heaters are more suitable for environments where household piping is relatively simple and installation conditions are not high. After understanding the respective advantages and disadvantages of the two, we will take a look at the purchasing techniques.

1, look at the name of the selected gas water heater water heater can be used more than 8 years, replacement is slow, choose a suitable product is critical.

Gas appliances must meet the relevant national standards. From the straight-lined type to the strong-row type, the safety performance of gas water heaters has been improved through several generations of products and postgraduate examinations. At present, there are almost no safety risks. However, some illegal manufacturers are still selling direct-in-line products that the State prohibits production and sales in order to make a huge profit. It is easy to risk. Second, it is very important to choose the right gas source. Many consumers do not look at the product parameters when purchasing a gas water heater, and as a result, they cannot use it after buying it home, causing unnecessary trouble. When buying a gas water heater, you should know what kind of gas source the product is suitable for. Common gas sources include gas, liquefied gas, and natural gas. Different gas sources have different pressures. The right gas source is selected to ensure normal use. Third, the geographical environment. Gas water heaters of the same type usually have two types of antifreeze type and common type. Gas water heaters are usually installed on well-ventilated balconies. The northern part of the country is colder in winter, and ordinary gas water heaters are very easy to freeze, causing inconvenience in use and in the south. Use a common type of gas water heater on it. Normally, the price of antifreeze products is slightly higher. Selecting suitable products according to the actual geographical conditions will save costs and make it more convenient to use.

The current market share of electric water heaters is as high as 70%, and electric water heaters have a relatively large power consumption. This is a large electricity consumer in the home. Choosing the right electric water heater can not only make the bath more comfortable, but also save energy.

2. Selecting an appropriate volumetric volume is an important consideration in how much water is stored in the water heater. Many consumers have misunderstandings to purchase. It is not that the bigger the volume, the better. For a family of 1-2 people, using an electric water heater with a capacity of 40 liters is sufficient. For a family of 3-4 people, 60-80 liters of electricity can be considered. Water heaters, a reasonable use of capacity, can not only guarantee the hot water needed for bathing at the same time, but also save energy, but also shortened the heating waiting time.

3, safety electric water heaters collect water, electricity in one, safety can not be ignored. Usually the body of the water heater has some special technical signs, such as the anti-electricity wall, which uses the resistance of the water itself (for example, the national standard requires that the resistivity of tap water should be greater than 1300 Ω.cm at 15°C), and it must pass through the electric water heater. The selection of the material of the water pipe (insulation material), the determination of the pipe diameter and the distance form the "electricity barrier". When the electric water heater is energized, the water heating the tank even if it has electricity will be attenuated by the resistance of the water itself when passing through the “electricity barrier” to achieve the purpose of isolating the electricity, so that the water heater enters and exits the water at both ends to reach almost Zero voltage and very weak current below the national standard 0.25mA/kw ensure user safety.

4, the inner core of the choice of electric water heater components is not a heater, not the circuit board, but the liner. The heater and circuit board are broken and can be repaired directly. If the tank is broken, the product can only be replaced. It can be said that the quality of the bladder directly determines the service life of the electric water heater. At present, many well-known brands have their own liners, more well-known A. O. Smith's Jin Guilin, and so on, buy electric water heaters to say it is picking liners.

5, power selection At present, many electric water heaters have speed heat function, although it can not achieve the heat effect, but also greatly reduces the heating waiting time. Nowadays, the pace of life is fast, and fast-speed products are more liked by young people. However, the premise of fast heat is achieved by high power, the power of ordinary electric water heaters is usually 2000-2500W, and the power of fast-heating electric water heaters may be as high as 5000W or so, which brings serious load to the entire home circuit. Can not blindly pursue the effect of rapid heat, but also based on the actual electricity environment, choose the right power products.
