Advantages and disadvantages of different types of gas water heaters

Gas water heaters are classified into direct discharge, flue gas, forced discharge, and balanced types according to their different forms. Below, Monkey Jiji will introduce the advantages and disadvantages of these water heaters to everyone.
1 Flue gas water heaters: These flue gas water heaters are slightly better than online water heaters that are prohibited from use. It is installed with an exhaust pipe on the basis of a direct discharge water heater, but it is also installed indoors, consuming indoor oxygen. However, the exhaust gas after combustion is discharged outdoors through the installed exhaust pipe. The water heater must be equipped with a flue. Pay attention to smooth exhaust from the flue during use to prevent backflow. Simply omitting the installation of exhaust pipes is illegal.
2 Direct discharge gas water heater: This type of water heater is not suitable for use. Due to being installed indoors, the oxygen burned during operation consumes the air in the bathroom and there is no corresponding exhaust channel. The smoke generated after combustion is also emitted indoors. Considering the danger of use, it has now been discontinued, but it cannot be ruled out that there are second-hand goods circulating in the market.
3. Balanced gas water heater: This is currently a popular gas water heater. The outer shell is sealed, and the flue integrated with the outer shell is made into two layers, inside and outside. The oxygen consumed is outdoors, supplied through the outer layer of the flue, while the indoor exhaust gas is discharged from the wall to the outside through the flue. The smoke generated after combustion is discharged from the inner layer of the flue to the outside, neither consuming nor polluting the indoor air. But installing such a water heater requires reserving a channel like installing an air conditioner, which can be discharged through a window.
4. Forced exhaust water heater: Add a smoke exhaust motor on the basis of the flue type to exhaust the exhaust gas to the outside through the flue. During operation, the flue gas is forced to be discharged outdoors through the flue, but the oxygen required for combustion is still taken from indoors, which is only a small correction. It is important to pay attention to installation standards. There may be some flaws during self installation. It is better for professional bathroom installers to install water heaters at home.
The above are the advantages and disadvantages of different types of gas water heaters. I don't know if everyone is aware. I hope everyone can choose a gas water heater that is more suitable for their own home
