When in-line gas water heaters are in use, what is the difference between them and strong in-line water heaters? When the forced discharge water heater is in use, it can use some particularly long heat transfer tubes and a heat exchanger with a large metal contact area. The working principle is that the heat of the gas after combustion is very good. It is hoped that we can understand the fact that it is passed to the metal plate to heat up.
There are actually many classifications of gas water heaters. When household gas is used quickly, in fact, water heaters include direct gas water heaters and flue-type water heaters according to the way the flue gas is discharged. It includes the types of forced discharge water heater and balanced water heater.
Since the waste flue gas of the direct exhaust gas water heater is directly discharged indoors, and the flue gas contains toxic gases such as carbon monoxide, it is easy to pollute the indoor air and easily cause safety accidents. It was banned by the state from sale. Therefore, the direct discharge gas water heaters used in users’ homes have already exceeded the scrapping period of 8 years, and even most households have used direct discharge water heaters for more than 10 years, and the safety hazards have intensified.
The water flow rate of the straight-line gas water heater is mostly 5 liters or 6 liters. Due to the small water flow rate, the comfort of bathing is significantly reduced, especially in winter. The thermal efficiency of the direct exhaust gas water heater is about 80%, while the thermal efficiency of the forced exhaust gas water heater is more than 88%. Gas water heaters are all products above the secondary energy efficiency standard, and the thermal efficiency of the condensing gas water heater produced first has reached 98%. Therefore, in terms of thermal efficiency, forced exhaust gas water heaters are more energy-efficient than direct exhaust gas water heaters.
When we are using it, when the direct discharge gas water heater is being disposed of, in order to prevent potential safety hazards from recurring, therefore, when using this kind of direct discharge gas water heater, it must be forcibly withdrawn and destroyed. Only then can it bring benefits to our peace, and I hope we are familiar with this knowledge.
