How to choose a safe and easy-to-use gas stove and water heater

In the face of numerous brands, models and various introductions from the salesmen, it is not easy for customers to choose a gas appliance (cooking stove and water heater) that is suitable for their own and easy to use If you happen to buy a good product, it will be easy to use If you buy a product of poor quality or unsuitable, you will have a lot of trouble when you use it, or even can't use it at all It is not Zui's fault that it can't be used From past experience, it has been proved that accidents caused by quality problems or improper use of gas appliances occur from time to time, which may endanger personal and property safety Now I will introduce a few common sense for you to help you purchase gas appliances normally First of all, you should know what kind of gas is used in your home first, because different kinds of gas, different kinds of gas appliances should be used, that is to say, one kind of gas appliance can only be used for one kind of gas, and there is no gas appliance for all kinds of gas If the purchased gas appliance does not match the type of gas used in your home, it can not be used if it is light, and it will cause poisoning or even explosion or fire, with unimaginable consequences Gas classification: there are three main types of gas for domestic use, i.e artificial gas, natural gas and liquefied petroleum gas Each kind of gas can be divided into different kinds of small gas according to the different composition of the gas For example, liquefied gas has 20Y, 22y, etc the gas appliances of 20Y and 22y can not be used in general We generally don't know the specific small gas types However, we don't need to worry about it, because the manufacturer must go to the local area to collect gas before producing products for a certain area, and only after analyzing the gas types can it be produced Therefore, the regular manufacturer will Products sold locally are suitable for use in the region Speaking of this, I also warn you not to use the gas appliances purchased in other provinces or cities to avoid accidents Liquefied petroleum gas: what Zui easily recognizes is liquefied petroleum gas, and the bottled gas bought is liquefied petroleum gas, Liquefied petroleum gas is in liquid state in the cylinder When it is used, it comes out of the valve of the cylinder through the pressure reducer, and it is the vaporized combustible gas What about the leakage of LPG? Liquefied petroleum gas itself is colorless and tasteless Once it leaks, it can't be detected Therefore, the state requires adding deodorant to liquefied petroleum gas, which is the smell we smell when it leaks Once it is found that the liquefied petroleum gas in the home leaks, the valve of the steel cylinder shall be closed immediately, and then the doors and windows shall be opened to let the indoor air circulate Pay special attention not to ignite and turn on the light LPG belongs to inflammable and explosive materials, which may explode when encountering the fire Artificial gas, natural gas, artificial gas and natural gas are all piped to each household Some City liquefied petroleum gas is also piped to the user When buying gas appliances, you must explain what kind of gas your home uses What about leakage of artificial gas and natural gas? Artificial gas and natural gas are lighter than air Once gas leakage is found, gas valve shall be closed immediately, doors and windows shall be opened to let indoor air circulate Remember, do not turn on the electric lamp or lampblack machine, because the spark of these electric switches will often become the ignition source of gas explosion How to choose gas stove gas stove can be divided into two types according to different installation methods: Desk stove and embedded stove Desk stove is a kind of stove with the whole stove on the table; embedded stove is to embed the main body of the stove under the table, which can make the kitchen look more beautiful The whole kitchen generally adopts embedded stove Choose a good gas stove should also pay attention to the following aspects Logo: when you tell the salesmen the gas type in your home, they will show you the corresponding gas type stove At this time, you can also check whether the applicable gas type on the product label is consistent with your home If the label of applicable gas type cannot be found on the stove, this kind of stove must be unqualified and cannot be bought Stove surface materials: there are mainly two kinds of stove surface materials: stainless steel and toughened glass The stainless steel stove surface materials are solid, with good finish and beautiful appearance, but the surface finish will be worse after long-term use, and the stains are difficult to clean and easy to leave marks At the same time, the thicker the stainless steel stove surface is, the better According to the requirements, the thickness of stainless steel plate used for the stove panel shall not be less than 0.3mm At present, most of the stoves sold on the market are 0.4mm thick, some of them are 0.5mm thick, while some of the inferior products are less than 0.3mm thick, which are prone to collapse and personal injury You can press the stove surface a few times to see if its steel is good If you press it up and down, Zui will not buy the stove with the sound of collapse Secondly, the metal edge around the stove, including the metal disc placed at the fire hole, should be gently touched by hand If it is smooth everywhere, it will be safe when cleaning in the use process If it feels a bit rough, it is easy to scratch the hand when cleaning in the use process The surface of the glass stove is beautiful and easy to clean After long-term use, it is easy to be bright as new However, if you buy inferior products, it is easy to crack the glass in the process of use Furnace head: the furnace head is mainly made of stainless steel, cast iron and copper forging Because the furnace head is baked by fire for a long time, it is easy to deform, so the furnace head material and thickness are very important Generally, the heavier the furnace head, the better Firepower: Chinese cooking is mainly stir fried, and at least one stove head is required to be large firepower to meet the needs of stir fried That is to say, the heat flow is generally 3.6kw to 4.2kW, and the other can be less than 3.6kw, so as to use when steaming, boiling and boiling soup Shape of fire cover: now the gas stove is divided into straight fire cover and rotary fire cover according to the shape of fire cover Generally, the rotary fire cover has high heating efficiency and concentrated fire power, which is suitable for stir frying However, the carbon monoxide content in the flue gas of rotary fire is easy to exceed the standard, while the fire power of direct fire cover is relatively uniform, and the carbon monoxide content in the flue gas is generally not easy to exceed the standard In addition to the above, there are two key points that cannot be ignored First, it is necessary to operate it several times by hand During operation, it is necessary to pay attention to whether it feels flexible, smooth, unsmooth and wrinkle free The operation should be smooth and easy At the same time, it is also necessary to pay attention to whether the ignition device is bright, white and continuous If the ignition is not continuous or red, such ignition device may have problems The second point is the pot holder, which should be as thick as possible so as not to burn out after a long time The pot holder should be able to put both the flat pan and the sharp pan, so it is convenient to use In addition, the claw of the pot support shall not be too long The longer the claw is, the more toxic gas carbon monoxide will be in the flue gas when it is used in the future We have introduced a lot of knowledge about how to purchase gas water heaters We will not go into details here We still need to pay attention to the types of gas used at home In addition, there are two key problems in choosing water heater Zui, one is what type to choose, the other is how big to choose Water heaters can be divided into many categories according to the installation method and use I will only introduce the common domestic water heaters on the market here 1 You may wonder why the products that have been eliminated should be introduced to you? The reason for mentioning this kind of water heater is that there are many unsafe factors in this kind of water heater I would like to remind you that if anyone is still using this kind of water heater, you are advised to eliminate this kind of product for the safety of your family and replace it with a safer one 2 The flue water heater is safer than the direct discharge water heater, because when it is used, the flue gas can be discharged to the outdoor through the flue, and the toxic gas carbon monoxide in the flue gas will not affect the indoor safety However, there are certain technical requirements for the installation of the flue of the water heater, which are often not met by ordinary families, so the smoke exhaust effect is not good In addition, many families install the water heater in the room with the window facing north, and the flue outlet must go out from the North wall When the air is cold in the north, due to the influence of the back wind, it often affects the safe use, and it is easy to make the water heater in the night The water on the surface freezes, freezing the water heater In addition, if the water heater is installed in the kitchen, do not use the water heater when cooking and starting the range hood At this time, the flue gas can not be discharged, but it will produce a reverse wind due to the use of the smoke hood 3 The forced exhaust water heater is the forced exhaust water heater, referred to as forced exhaust water heater The main feature of the water heater Zui is that it is equipped with a blower, which forces the flue gas to be discharged to the outside by the power of the blower Because of the power of exhaust, the flue diameter is relatively small and the installation is easier In addition, the flue of the water heater is generally equipped with a wind shield When the water heater is used, the blower opens the wind shield and exhausts smoke outwards When the water heater is not used, the baffle automatically closes the flue and blocks the outside air In winter, the possibility of freezing the water heater is greatly reduced 4 Closed water heater this kind of water heater is sealed The air used for combustion and the exhaust gas are directly connected with the outdoor through pipes, which has nothing to do with the indoor ventilation Zui is safe when using this kind of water heater When in use, the power formed by combustion naturally enters and exhausts the air, which is called the balanced water heater If a blower is installed, the mechanical force is used for air intake and exhaust, which is called forced air supply and exhaust water heater When installing the water heater, there must be an external wall, which can lead the air supply and exhaust pipe directly to the outside, and the air inlet and exhaust pipe cannot lead to other rooms You can choose from the above water heaters according to your living conditions Let's introduce the size of the water heater The size of the water heater refers to how much hot water the water heater can produce per minute, that is, how much hot water can be produced per minute when the water temperature rises by 25 ℃ For example, the hot water production capacity of the water heater is 10 liters, that is, the temperature of the tap water (cold water inlet) is 15 ℃, which can increase the fire power of the water heater to Zui, which can produce 10 liters of 40 ℃ hot water per minute; when the temperature of the tap water is 5 ℃ in winter, although the fire power of the water heater is still in Zui, it can produce less than 10 liters of 40 ℃ hot water per minute, which is less than 10 liters; similarly, if In summer, the temperature of tap water is 25 ℃, and the same fire power, 40 ℃ hot water is more than 10 liters At present, most of the water heaters on the market rise from 6 to 16 liters The larger the water heater is, the more water and gas will be consumed The smaller the water heater is, the more water and gas will be saved If it's just water for living and shower, choose an 8-to-10 litre water heater If the living area of the family is large, and the chance of using hot water is more, a larger water heater should be considered If you have a bathtub at home, you should choose at least 12 liter or even 16 liter water heater, so that you can discharge water to the bathtub faster, and the water heater Zui is good to choose adjustable type, when you discharge water to the bathtub, you can adjust to large flow, and when you shower, you can choose small flow For families that need heating, you need to choose a dual-purpose water heater for heating and hot water supply In a word, it's more reliable to buy products from famous manufacturers In addition, I can tell you a simple and correct way to buy gas stoves and water heaters, and see if there is a "blue flame" certification mark on the products This certification mark is the certification mark of * to prove that the quality of gas appliances is qualified, safe and reliable When you buy it, you can
