What is an in line water heater like and what are the hazards?

The in-line water heater is directly discharged into the room after combustion, and the indoor ventilation will cause poisoning.

The in-line gas water heater is to directly discharge the exhaust gas after combustion into the room, a large amount of carbon dioxide and unburned gas, stay in the room, if you do not pay attention to the ventilation of the room, people inhale too much carbon dioxide and unburned gas will cause poisoning. So now the state advocates the use of strong exhaust gas water heaters, which have a fan inside, and when the gas water heater is used, it will automatically start to discharge the carbon dioxide generated by combustion and the gas that is not burned outside.

And the world deeply feels that the health of the guaranteed loan of the informal vest female summer **** summer everyone to the classroom to carry out the surprise designer baby found a set of underwear brand value is difficult to accept the interview to express satisfaction? I'd like to check it out too.

The straight row is about the same as the strong row, but the salesperson always wants you to buy the strong row.

There is a hot water delay in the outgoing water of the strong discharge, that is to say, the hot water is turned off once when washing in the middle, and then turned on, the strong discharge needs to start the exhaust first, and then ignite the gas, so the effluent has a cold section.

The inline discharge is that the oxygen in the home needs to be burned and directly discharged at home, in fact, the strong discharge is also to burn the oxygen in the home.

Because neither the straight row nor the strong row are installed in the bathing room, this oxygen consumption does not matter.

So it's better to be in a straight row, **cheaper.

In-line water heater andStrong exhaust water heaterThe difference:

1. The effluent flow rate is different

Inline gas water heater.

The flow rate of the water is mostly 5 liters or 6 liters, and the comfort of bathing is low due to the small flow of water. The flow rate of the strong exhaust gas water heater is mostly between 8 liters and 10 liters, which is more comfortable for bathing, and can meet the simultaneous use of the kitchen and bathroom.

2. The thermal efficiency is different

The thermal efficiency of in-line gas water heaters is about 80%, while the thermal efficiency of strong exhaust gas water heaters is more than 88%. Therefore, in terms of thermal efficiency, strong exhaust gas water heaters are more energy-efficient than inline gas water heaters.

3. Security is different

The forced exhaust water heater is to discharge the combustion flue gas outside, which is better than the inline water heater in terms of safety performance.

Precautions for buying a water heater:

1. When purchasing, you must pay attention to see whether there is a leakage protector, whether there is a self-test function, and whether the manufacturer has signed a contract with the insurance company.

2. Check the shell material, generally speaking, the fast electric water heater on the market at present.

The shell material is mainly metal panel, ordinary plastic or laminated film, in addition to ABS special rubber, etc., the water heater should be made of ABS special glue shell, which is characterized by flame retardant, heat resistance, high chemical resistance.

3. Choose products with high energy efficiency and good energy saving. Electric water heaters are used more frequently, and energy-saving water heaters are more cost-effective. According to the regulations, all kinds of electric water heaters should be labeled with energy efficiency stickers and energy efficiency grades.

It is divided into 1-5 grades, and products below grade 5 will not be available on the market.

With the continuous development of society, water heaters have almost become a must-have household appliance for every family, especially in the market, there are many types now, and it is very important to choose a good water heater, but we know very little about water heaters, so let us introduce to you what is an in-line water heater, as wellIn-line water heatersHazards and precautions for use.

1. What is an in-line water heater?

The in-line water heater is one of the earliest water heaters, the gas in-line water heater is a water heater with natural gas or petroleum gas and other gases as the energy source, the in-line water heater is mainly because the exhaust gas after combustion is directly discharged indoors, due to the incomplete combustion of the gas, the discharged gas contains a certain amount of CO and other components, which is very unsafe and prone to accidents, so the state has banned the use of it in 2000, and now the in-line water heater has been replaced by the strong exhaust and flue type.

2. Hazards of in-line water heaters.

1.When the in-line gas water heater is used, the exhaust gas produced by combustion is directly discharged indoors, and the main component of the exhaust gas is carbon monoxide, which is easier to combine with human hemoglobin than oxygen, which is easy to cause carbon monoxide poisoning, which is very dangerous. Gas water heaters can be divided into in-line gas water heaters and strong exhaust gas water heaters according to the different exhaust gas emission methods after combustion.

2.The main feature of the in-line gas water heater is that the exhaust gas generated is discharged directly into the air while burning the hot water. In this way, in the case of a closed room, it is easy to cause harmful gas accumulation and oxygen deficiency, which can lead to personal poisoning, which is harmful to health at least and leads to **.

3. Precautions for the use of in-line water heaters.

1. Regular inspectionDuring the use process, the water heater needs to be inspected every once in a while, and when smoke leakage, blockage or backfill occurs, please stop using it immediately.

2. It is forbidden to place flammable and volatile materials around the water heater, and it is forbidden to place flammable and volatile materials around the water heater, and it is forbidden to place towels and rags and other flammable materials on the exhaust port and gas supply port.

3. Pay attention to maintain good ventilationPay attention to maintain good ventilation, do not hang items on the air supply and exhaust ports of the room, so as not to affect air circulation. Before each use, check that the windows or exhaust fans of the room where the water heater is installed are open and well ventilated.

4. Check whether the gas valve is closed after use, check whether the gas valve is closed, and check whether the gas supply pipeline is in good condition. Pay attention to replace the rubber hose regularly, please use soapy water to check whether there are bubbles at the hose connection, and report for repair in time if there is air leakage.

5. In-line gas water heaters are prohibited from being used because of the potential safety hazards, but there are still unscrupulous merchants in some places who are secretly selling, for their own safety, it is recommended that you do not use in-line gas water heaters, and at the same time pay attention to the correct use when using other water heaters.

The above is for you to introduce some knowledge about the in-line water heater in the bird, I believe that you will have a new understanding of the in-line water heater after reading the above article, if there are any problems with home improvement, please continue to pay attention.

Water heaters are more common in our lives, but the brand of water heaters will be different, and the styles will be different, such as in-line water heaters are one of them, but this kind of water heater has certain harms, so we must pay attention to it when using, thenInline water heaterWhat are the hazards? What are the brands of inline water heaters? Let's introduce it to you.

1. The hazards of in-line water heaters.

1.Do not close the gas valve after using the stove, when the hose and the connection are loose or the stove valve is faulty, it will lead to gas leakage, fire accidents, so close the gas valve after using the stove, confirm that the switch is in the closed position before using the stove, and the pipeline gas user should close the main valve when going out for a long time;

2.In-line water heaters are basically installed in old residential areas built at the end of the last century, and are basically installed in toilets with poor ventilation conditions. At that time, many families were installed with gas water heaters later, and the installation in the bathroom caused little damage to the previous decoration, which laid the groundwork for the continuous poisoning accidents that occurred in the future.

3.The use of inferior and expired pressure reducing valves makes the pressure regulation unstable, which is easy to damage gas appliances and lead to leakage accidents. The pressure reducing valve is overused, and the rubber sealing ring is easy to age and leak, which may lead to the occurrence of ** accidents.

The service life of the pressure reducing valve is 5 years, and the pressure reducing valve with the production certificate should be purchased; 5. The use of bottled gas, pipeline gas and bottled gas in high-rise buildings is very prone to gas accidents, and mixing is strictly prohibited.

Second, the brand of in-line water heater.

1.Haier electric water heater solves the water heater safety problem caused by poor electrical environment, even if you have no ground wire at home, you can ensure the safety of your bath. Customized domestic hot water according to bathing habits; Make an appointment on time, heat up in advance, and take a bath as you like; Medium temperature insulation function, the water temperature is kept at 40 to meet the water demand.

2.The appearance of the Siemens DG65165BTI electric water heater is simple and fashionable, the white piano lacquer body is more fresh and refined, the large screen touch, and the graphical operation interface is simple and easy to understand, which avoids the cumbersome operation. The inner tank is made of ultra-thick environmentally friendly insulation materials, which has a better thermal insulation effect and avoids high energy consumption caused by repeated heating to a certain extent.

3.Midea Group was founded in 1968, registered the Midea brand in 1981, and currently has more than 20 production bases at home and abroadIn the evaluation of "China's valuable brands" in 2012, the brand value of Midea reached 100 million yuan, which was at the top.

There are many kinds of brands of water heaters, but there are also many kinds of styles, so what are the hazards of inline water heaters and what are its brands, I think after reading the above introduction, everyone knows about these, so if you want to know more decoration information, please continue to pay attention to it.

Nowadays, people and good people have installed water heaters at home, but when installing water heaters, some people install in-line water heaters, so how to use them, but I don't know much about these, so let's introduce them to youIn-line water heatersOne. How to use an in-line water heater.

1.We take care to maintain good ventilation and do not hang items on the air supply and exhaust outlets in the room so as not to affect the air circulation. Before each use, check that the windows of the room where the water heater is installed or the exhaust fan are open and well ventilated.

2.There are also safety checks on the water heater at regular intervals during use. However, in the event of smoke leakage, blockage, or backfilling, discontinue use immediately.

3.In addition, it is forbidden to place flammable and volatile materials around the water heater, and it is forbidden to place flammable materials such as towels and rags on the exhaust grip and air supply port.

4.Finally, after use, we check that the gas valve is closed, but we always check that the gas supply pipe is in good condition. Also pay attention to the regular replacement of the rubber hose, then please use soapy water to check whether there are bubbles at the hose connection, if there is any air leakage, report the first repair in time.

Two. In-line water heater hazards.

1.In the use of in-line water heaters, they are basically installed in the old residential areas built at the end of the last century, but they are basically installed in the toilets with poor ventilation conditions. However, at that time, many families were later installed with gas water heaters, but installing them in the bathroom caused the least damage to the previous decoration, which laid the groundwork for the continuous poisoning accidents that occurred in the future.

2.Next, the in-line water heater uses the smoke exhaust pipe to extend from the water heater to the outdoors, but it has a lot of pollution to the environment.

3.In addition, when the in-line water heater discharges the exhaust gas to the outside, the emission rate is low, and there is still exhaust gas residue in the room, which is prone to fire.

4.Finally, let's talk about the structure and use conditions of the in-line water heater have certain limitations, but because the oxygen required for combustion is taken from the room, and the gas produced after combustion is also discharged indoors, if the indoor ventilation effect is poor, it will cause carbon monoxide poisoning.

When we use in-line water heaters, we don't know how to use them, and the above article is about how to use in-line water heaters and the dangers of in-line water heaters.
