Do you know how many years a gas water heater lasts?
The safe service life of gas water heaters" national standard clearly stipulates that the general safety service life of water heaters is about eight years. In the specific use, we all know that in many homes, especially rental houses, the older generation of parents' homes, the service life of the electric water heater completely depends on its quality, if the water heater is not bad, it can be used for ......
However, if you encounter the following situations, it means that it is time to replace the gas water heater in your home, otherwise it is very easy to have safety risks!!
When taking a bath, the hot water comes slowly, and the water temperature is still hot and cold?
When the water heater is in working condition, it is accompanied by abnormal noise.
The water heater takes a long time to ignite, and it often does not ignite.
When the gas is not stopped, the water heater does not respond when it is started.
01.There are hidden dangers in overdue water heaters.
Gas water heaters that have been used for more than 8 years, inside the machine that we can't see, the aging of the components is very easy to cause gas leakage, and in the case that we don't know it, a slight open flame will lead to gas **, which is very dangerous.
The line is aging and there is a risk of electric shock.
Expired gas water heaters may have the problem of aging wiring, easy to leak current during use, and once leakage, electric shock accidents may occur when bathing or kitchen water.
The experience is poor, and it costs more gas and money.
Overdue gas water heaters not only slow down the hot water, but also often hot and cold during use, which seriously affects the user experience.
After long-term combustion, the heat exchanger will accumulate a large amount of carbon, causing the water tank to rust, and at the same time, the scale will accumulate in the pipeline, which greatly reduces the thermal efficiency of the gas water heater, which is very gas-consuming.
02.Use a gas water heater properly.
When purchasing a water heater, you should check whether the water heater is consistent with the current gas source. Read the instruction manual carefully, and regularly clean and maintain the water heater (once a year) to ensure the normal use of the water heater.
Gas water heaters are strictly forbidden to be installed in closed bathrooms, basements and other rooms. It shall not be installed in places with flammable materials such as gasoline, kerosene, volatile agents, adhesives, etc., and the installation location must be free of any obstructions.
If the flue is not installed, the exhaust gas is easy to stay indoors, and it is easy to cause suffocation or poisoning of indoor personnel.
It is strictly forbidden to use in-line water heaters.
When using a gas water heater, open the windows, maintain good ventilation, and do not bathe for too long.
03.So how to choose the right gas water heater?
The size of the capacity. Most models of gas water heaters on the market only have two capacities: 13L and 16L, which can also meet the needs of most families.
In principle, the larger the capacity of the water heater, the greater the amount of hot water produced. If you have a bathtub or multiple water points at home, try to choose a 16L water heater.
2. Type of gas water heater.
Water heaters are divided into four types: in-line, strong, balanced, and flue according to the exhaust type, and the in-line type has long been eliminated, and the most common is the strong exhaust gas water heater.
Sentai gas water heaters are all strong exhaust water heaters, and there is a fan inside the machine, one is the blast and the other is the exhaust, and the blast is better than the exhaust.
3. Water tank material.
The water tank, also known as the burner, is the part that turns cold water into hot water. At present, the two common materials of water heater tanks are "stainless steel" and "oxygen-free copper", both of which have their own advantages and disadvantages.
Stainless steel water tank, its anti-corrosion, anti-scaling effect is better.
Oxygen-free copper water tank, better thermal conductivity, faster heating, repeated combustion without deformation.
4. Constant temperature performance.
The main factor that determines the constant temperature effect of a gas water heater is its temperature control method
Water volume servo "water and gas double adjustment" only gas proportional valve.
Model recommendation. After talking for a long time, it came to the specific model recommendation:
Sentai Gas Water Heater C15
In view of the problem that the water heater is easy to freeze and crack in winter, this C15 water heater is specially designed with intelligent anti-freezing protection, which will automatically circulate and heat when the inlet water temperature is too low to prevent the water pipe of the water tank from freezing and breaking. There are also multi-dimensional safety protections such as gas protection, electricity protection, water protection, health protection, and equipment protection, so that bathing is more assured. At the same time, it is also equipped with a dynamic circulating zero cold water preheating system, built-in circulating water pump, when the water heater detects that the water temperature in the return pipe is lower than the insulation temperature set by the user, it immediately starts the circulating water pump, and the cold water in the water pipe is heated, which has the effect of "hot when it is opened, and hot when it is opened again", and there is no need to let go of a large amount of cold water before hot water flows out, and you can enjoy a comfortable bath at any time.
The above is to share with you today the matters to be paid attention to when using gas water heaters, there are a variety of gas water heaters on the market, with different functions, in general, as long as you buy, meet the above points, you can buy a satisfactory water heater.
