Water storage electric water heater refers to a fixed appliance that heats water. It can store hot water for a long time or temporarily, and is equipped with a device that controls or limits the water temperature. Water storage type electric water heaters commonly used in homes are convenient to install and inexpensive, but need to be heated for a long time and can only be used after reaching a certain temperature.

There are many brands of electric water heaters in the market, and the quality varies widely. Most of the customers are non-professionals, which is difficult to identify. Water storage electric water heater is a national mandatory inspection product.

Storage-type electric water heaters are divided into:

1) Household water heaters generally use a single-phase 220V power supply with a power not greater than 2.5kW, and some are used in villas and other places where water is consumed

Advantages: high safety performance and clean energy. Multi-channel water supply. Can be used for showers, bathtubs, laundry,

The capacity of a water storage electric water heater is in liters (L). The larger the capacity, the greater the hot water supply capacity of the water heater. At present, the common capacities in the market are: 10L, 15L, 40L, 50L, 60L, 80L, 100L, and a few manufacturers can produce more than 100L products. Users can choose the capacity of the water heater according to the purpose, the size of the family and the water habits. 10L-15L water heater is generally used in the kitchen to wash dishes, wash dishes or wash the face, brush your teeth, so people call it kitchen treasure or kitchen treasure. Water heaters for bathing should choose a capacity of more than 40L. One person should use a water heater with a capacity of 40-50L; two people should use a water heater with a capacity of 50-60L; a family of three should choose a water heater with a capacity of 80-100L; 3 Families with more than one person are suitable to use water heaters of 120L or more; if you are used to bathing in a bathtub, it is best to choose a water heater of 150L or more.

1) liner

The inner tank is the core component of the water heater, which directly affects the safety performance, service performance and working life of the water heater. When choosing a water heater, the user should be concerned about whether the material of the steel plate of the water heater is a titanium-containing alloy, whether the thickness is thick enough, whether the welding process is advanced and reliable, whether the quality of the enamel glaze is guaranteed, and whether the sintering process is advanced.

1) Wall-mounted domestic water heater

(1) Installation position: ensure that the wall can bear twice the weight of the water heater filled with water, and the fixing parts are installed firmly; ensure that the water heater has maintenance space.

Ways to save energy

1. For households that do not use hot water frequently, here refers to the use of hot water for bathing at least once every two days. The frequency of use is not high. In such families, we recommend that you start heating one hour before bathing and turn off after bathing. When the water heater is turned off. In this way, the power consumption can be minimized, thereby saving electricity costs to the greatest extent.

2. For households that use water heaters every day, just for bathing, and not using a lot of hot water, we recommend that you turn on the water heater for heating about an hour before taking a bath. If you take a bath at a relatively fixed time every day, you can purchase a computer-controlled water heater product and use its timing heating function to complete it. Turn off the water heater after taking a bath.

3. For the situation of frequent use (usually a water heater is used in the kitchen and bathroom at the same time, hot water is used for cooking, washing dishes and bathing), we recommend to keep the water heater on all the time, according to the frequency of use and the use of hot water The amount of water to adjust the temperature of hot water, when the amount of use is not large, you can lower the temperature a little, when the amount of use is large, you can increase a bit.

4. For the case where it has been used (usually used by commercial users such as hair salons), it can only keep the water heater always on, but it can also adjust the temperature of hot water appropriately according to the number of guests. This saves electricity bills to the greatest extent.

It is normal for the safety valve to drip water during heating

When the electric water heater is heating, a small amount of water droplets may sometimes come out of the safety valve. This is normal because when the machine is heating, the water expands due to heat and the volume becomes larger, but the capacity of the liner does not change, so the pressure increases When the safety valve detects that the pressure increases, it automatically starts to release water and release pressure, so there is a dripping phenomenon that we see. The user cannot adjust or block the pressure relief hole of the safety valve at will. A plastic hose can be connected to guide the drip to the floor drain.

Misunderstandings for safe use

1. Myth 1

Qualified water heater = safe bathing

With the increasing maturity of electric water heater technology, most of the electric water heater manufacturers have comprehensively resolved the issue of water heater power safety. And users also more agree with this statement, that electric water heater products are qualified, there is no worries about bathing. But there are still frequent electric shock accidents, users can not help but ask: Is a qualified water heater really safe? What caused these accidents?

According to experts, the standard of China's electric water heater is equivalent to the European IEC (

From the data of the first half of 2013, the growth of electric water heaters is good, with both double-digit growth in retail volume and retail sales. With the arrival of the peak sales season, there is still room for growth. It is worth noting that the sales growth of electric water heaters is significantly higher than the sales volume. This is achieved by enterprises by increasing the unit price of products. The same situation also occurs in the gas water heater market.

From the market share point of view, although it was not included in the new round of household appliances energy saving subsidies that ended in June, electric water heaters still occupy the mainstream of the market. According to the monitoring data of Zhongyikang, the retail sales of electric storage water heaters and instantaneous electric water heaters accounted for 60% of the market share in the first half of 2013, much higher than gas water heaters.

Although the absence of subsidies will not have a significant impact on the industry position of electric water heaters in the short term, as the role of energy-saving subsidies gradually appears, the market share of electric water heaters has gradually decreased. From the monitoring data of Zhongyikang, it can be seen that compared with the shrinking market share of electric water heaters, the market share of gas water heaters has slightly increased. With the implementation of the step price system for residents in China, the European Union and the United States have issued environmental protection directives restricting the production and sale of electric water heaters. The prospect of electric water heaters with large energy consumption is not optimistic. However, industry insiders also said that in view of China's huge third and fourth level market demand to be released, the electric water heater market will continue to grow steadily in the future.

With the increase of brand concentration, leading companies have further consolidated their leading advantages, and the market performance in the first half of the year is also better than the overall industry level. On the basis of safety, various companies are paying more and more attention to improving thermal efficiency, energy saving and rapid heating have become market highlights, and the trend of high-end products is more obvious.
