What are the dangers of direct vent water heaters? How to use safely?

Discharge water heater is a more convenient water heater, it is easy to operate fast heating, so it is very popular, but its safety has been a concern, in our daily life, there is no shortage of heard of direct-vented water heater caused by large or small hazards, so how should we respond to these security risks? Today I would like to introduce you to the hazards of direct-vent water heaters, in our daily lives, we should be how to use in order to protect their own safety, I hope to use direct-vent water heaters friends to understand.

A direct-vent water heater hazards:

1. Direct-vent gas water heater in use, the combustion of exhaust gas produced directly discharged indoors, the main component of the exhaust gas is carbon monoxide, more than the oxygen and the human body easier than the hemoglobin combination of oxygen, easy to cause carbon monoxide poisoning, very dangerous. Gas water heaters can be divided into direct-vent gas water heaters and forced-vent gas water heaters according to the different ways of discharging exhaust gases after combustion.

2. The main feature of the direct vent gas water heater is that while burning hot water, the resulting exhaust gas is discharged directly into the air. In this way, in the case of a closed room, it is easy to cause the accumulation of harmful gases and the lack of oxygen, which can lead to personal poisoning, a minor health hazard, or lead to casualties.

3. Flue water heaters and forced-vented water heaters, the same as its combustion of the oxygen required to be collected from the room. The difference is that the flue-type water heater is installed at the top of a metal pipe with a diameter of 80 to 120 millimeters to discharge the large amount of exhaust gas generated during combustion of the water heater to the outdoors according to the principle of air pressure difference. However, it is not equipped with any air extraction equipment and thus is extremely unsafe to use.

4. Forced exhaust water heater is in the flue water heater on the basis of the machine inside a set of electric fans, will be mandatory exhaust outdoor, relatively speaking, safety is more secure. Therefore, the flue type and forced exhaust water heater must be installed outside the bathroom.

Two, direct vent water heater use notes:

1, pay attention to maintain good ventilation, do not hang items in the room on the supply and exhaust vents, so as not to affect air circulation. Before each use, should check the installation of water heater room window or exhaust fan is open, ventilation is good.

2, in the process of use, need to be every once in a while on the water heater safety checks. When smoke leakage, blockage or backed-up wind occurs, please stop using it immediately.

3, prohibited in the water heater around the placement of flammable, volatile substances, prohibited in the exhaust port and gas supply port on the towel, rags and other flammable products.

4, after use, check whether the gas valve is closed, often check whether the gas supply pipe is intact. Pay attention to the regular replacement of rubber hoses, please commonly used soapy water in the hose joints to check whether there are bubbles, such as gas leakage, timely repair.

5, direct-vent gas water heaters because of the use of safety hazards, so it is prohibited to use, but there are still unscrupulous merchants in some places in the sneak sales, in order to consider their own safety, we recommend that you do not use the direct-vent gas water heaters, but also in the use of other water heaters should also pay attention to the correct use.

The above is a small introduction to the direct-vent water heater, including its hazards and safe use, I believe we have a certain understanding of the safe use of direct-vent water heaters, in fact, no matter what kind of water heater has its safety hazards, as long as we pay more attention to understand its instructions, it can be very good to put an end to these safety hazards. Finally, I suggest that you, direct-vented water heaters are not advocated today, with the development of science and technology, I believe that there will be more and more safe, reliable and convenient water heaters come out, everything should be safety first.
