The first is to look at the brand. See whether the manufacturer has a scale, whether the production history is long, and whether it has passed various quality and management certifications;
The second is to choose categories. Electric water heaters are generally divided into two categories: water storage type and quick heating type. Fast heating is faster, but because of its high power, ordinary household meters can't bear it. The water storage type has the characteristics of uniform outlet water temperature, moderate heating power and high safety factor, and is the first choice for household use.
The third is to look at performance. Understand whether the products are particular about material selection, whether there are world-advanced technologies and measures in terms of high pressure resistance, high temperature resistance, anti-corrosion, leakage prevention, heat preservation and energy saving, and whether they have passed a number of safety and quality certifications;
The fourth is to choose capacity. Generally, 50 liters is selected for a family of three, 80 liters for a family of four or five, and electric water heaters above 100 to 120 liters should be considered for more than five;
Finally, see if it is convenient for daily maintenance. A good water heater is humanized in design, which is convenient for users to remove the scale in the inner container by themselves.
Choosing a water heater in autumn and winter is learned.
With the arrival of winter, water heaters have once again become the focus of consumers' attention. Experts remind consumers that the choice of water heaters should be based on the actual situation of the family and choose the right products. Below, let's talk about how to choose a satisfactory water heater according to different family situations.
If the new house to be renovated is a new house that has not been renovated, you can choose an electric water heater or a gas water heater. If your home pays great attention to saving water and the bathroom is far from the kitchen, it is recommended to install two water storage electric water heaters, one in the bathroom and the other in the cupboard. Because it can be directly installed near the water outlet, it is more convenient to use, and the price of regenerative electric water heater is much cheaper and the installation is much more convenient. It is worth noting that Haier electric wall water heater is recommended when purchasing electric water heater, because its patented electric wall technology can ensure the bathing safety of consumers in any electricity environment.
If the daily hot water consumption of the family is large, and the distance between the kitchen and the bathroom is close, from the perspective of energy saving, it is recommended to choose a gas water heater with a slightly larger water supply. At present, domestic brand Haier and foreign brands Linnei and Energy Efficiency are the main competitive brands in the high-end market of gas water heaters, and their main sales models all supply more than 9 liters of water, which can fully meet the demand of ordinary families for hot water.
A decorated family
If you live in an old residential building, or the building is over 10 years old, you must consider the safety of electricity when buying a water heater. It is recommended to use water storage electric water heater. The electricity consumption environment of urban residents in China is not optimistic. A national household electricity safety survey shows that nearly 70% of domestic households have different levels of electricity safety hazards due to different reasons such as no grounding wire or unreliable grounding, aging lines and unqualified sockets.
In terms of safety protection, electric water heaters are the most reliable among the three categories of products: electricity, gas and solar energy. For example, the newly listed Haier A8 series electric water heaters not only adopt the anti-electric wall technology, but also apply the international advanced "safety early warning" technology for the first time in China. If the ground wire is charged or abnormal, the "safecare" sign on the A8 control panel will light up to remind the user to eliminate hidden dangers at the first time.
Families who change water heaters.
For the sake of life safety, it has become the common sense of consumers that water heaters cannot be used beyond the time limit, and the replacement market is growing. No matter whether the electric water heater or gas water heater is used originally, it is very convenient to replace it with an electric water heater with an anti-electricity wall. If you use a Haier water heater purchased before April 2002 at home, Haier service personnel can also upgrade the electricity-proof wall at home for free. You only need to spend 40 yuan on materials, so you can avoid the trouble and expense of replacing a new machine.
But for other users, they are used to using gas water heaters. When changing the machine, for the convenience of use, gas water heater products with wire control technology are often selected. However, wired remote control will inevitably use a long control line, which will affect the appearance; Taking dark lines is not only troublesome, but also causes some damage to the wall or top surface. In this case, the best choice is to buy a gas water heater that can be remotely controlled wirelessly. A few days ago, Haier launched a "wireless communication" gas water heater, which can be wirelessly controlled through the wall. This "radio frequency" wireless control technology enables the control signal to penetrate the three-story wall and is effective within 30 meters, which can fully meet the needs of duplex houses and even villas. It is reported that the remote control of this product adopts advanced "code matching" technology, and the products will not affect each other; In addition, it also has frequency conversion constant temperature technology, so how much water temperature you need can be adjusted at will, and the error is within 1 degree.
