Water heaters are an essential electrical appliance for every household, and electric water heaters that can store water were more popular in the past. However, there are many problems with electric water heaters, such as: you need to wait for hot water to boil, and if there are many people in the family, it is a waste of time. Moreover, the water storage tank needs to be cleaned regularly, otherwise the water quality will become poor and prone to problems.
Therefore, gas water heaters are more popular now. There is no need to wait, it is hot as soon as it is opened, and no matter how many people in the family are not afraid. In addition, there is no water storage, so there is no need to worry about the water being dirty.
If you want to buy a popular water heater at home, you must keep this in mind"8 mantras".。Just buy it, it's very practical, and you definitely don't have to worry about stepping on the pit.
Some people may wonder that the capacity of an electric water heater is the amount of water that can be stored. However, gas water heaters do not need to store water, so what does capacity mean?
The capacity of a gas water heater refers to how much hot water can be produced per minute. The larger the capacity, the better it can meet the demand. If we choose a gas water heater, it is best to choose a capacity of more than 16L, and try not to choose less than 13L.
In-line gas water heaters have basically been eliminated, and now strong discharge or balanced water heaters are popular.
The strong discharge type is more suitable for kitchens and balconies, and its advantage is that it can effectively discharge toxic gases, but the consumption will also increase. The balanced water heater occupies less space, heats up quickly, has a large air outlet, and has less scale descaling, which is more suitable for the bathroom.
The lower fan is positioned close to the gas nozzle, which can quickly transfer heat to the hot water, and the heating performance is better. The upper fan has space limitations, which affects the thermal conductivity and reduces the heating performance.
In addition, the air outlet of the lower fan is far away from the human body, which is less susceptible to the interference of external airflow, which improves the stability of hot water and makes it more comfortable to use. The lower fan also reduces the risk of gas leakage, and if there is a problem, it will be easier to inspect and repair.
In short, the underhead fan is more comfortable, durable, and lasts longer.
Oxygen-free copper water tank is a high-purity copper material, which is relatively compared to stainless steel water tank. The thermal conductivity, ductility and corrosion resistance of oxygen-free copper water tanks are much stronger.
Moreover, the oxygen-free copper water tank does not produce any peculiar smell, is not easy to rust, and has the additional effect of sterilization and antibacterial. Although it is slightly more expensive, it is the first choice for people who pursue quality, safety, environmental protection and service life.
When we buy a gas water heater, try to choose a model with a thermostatic function. In this way, the stability and comfort of the water temperature can be ensured. It can avoid large fluctuations in water temperature, which affects the comfort and health safety of use.
Temperature control effect: water volume server, water and gas double adjustment, gas proportional valve.
For some old residential areas, or high-rise houses, there is often a situation of low water pressure. Therefore, we should choose a style that can be started with low water pressure, and do not choose a water heater with high starting water pressure requirements.
Otherwise, it will not be usable when the water pressure is low. Or, when the water pressure is unstable, it is easy to have hot water for a while and no hot water for a while, which seriously affects the comfort.
Fire safety is very important, if there is a gas leak, it may cause poisoning, ** and other dangers. Therefore, when we choose a gas water heater, we should try to choose a style with a boot self-test. What safety protection, flameout protection, anti-freezing protection and other functions, higher security.
For the average family, an ordinary gas water heater is sufficient. There is no need to choose a zero cold water heater, the so-called zero cold water heater is to boil water in advance so that the return pipe is filled with hot water.
Zero cold water is more suitable for situations where the bathroom and water heater are too far away, such as: large apartments, villas, etc. However, to achieve this effect, a return pipe needs to be installed. In addition, after the water heater is stopped, it is easy to pour cold water, which affects the use effect.
When buying a gas water heater at home, it is best to refer to the above 8 formulas. This can improve the use effect, use comfortably, and can also reduce unnecessary trouble.
