Gas-fired hot water boiler is a kind of hot water boiler. Gas-fired hot water boiler uses gas (such as natural gas) as fuel to heat water through burner to realize heating and provide hot water for daily life and bathing. The boiler has high intelligence, fast heating, low noise and dust-free. It is an economic hot sale which is very suitable for China's National conditions. Boiler variety. It is common for people to use hot water in their lives. However, there are still six misunderstandings in the use of hot water and the purchase of water heaters due to the influence of accumulated habits and old concepts.
Myth 1: Buying a water heater is just for bathing. In fact, hot water should be the leading role of domestic water, not only for bathing, but also for washing vegetables (removing pesticide residues), dishes (cleaning greasy efficiently), laundry (saving and making full use of laundry powder), mopping (effectively cleaning stains), car washing (protecting paint surface), and so on. This is not only the need of health and hygiene, but also the symbol of the improvement of the quality of life and the progress of human civilization.
Myth 2: "Solar energy can not be used in winter, not good to use". Actually, it's not. It's just as good in winter, because it's equipped with three high vacuum tubes of international technology, and hot water can be produced in cold conditions.
Myth 3: "Solar energy buys small economy". Don't think it's like a 25-inch color TV. It's smaller than a 29-inch color TV. It's all right to watch it. In fact, the difference between large solar energy and small solar energy is like color TV and black-and-white TV, which have essential differences. Big can let you always use hot water, everyone use hot water, everything use hot water, in the long run more cost-effective.
Myth 4: "It costs more to use hot water than cold water". From the cleaning and bactericidal effect, one time of hot water is worth five times of cold water. On the contrary, it saves water and promotes health.
Misconception 5: "Use hot water to heat now, to wait". Actually, it's not, it has the advantages and characteristics of abundant hot water, long heat preservation time and perfect combination of photoelectricity. It makes you want to wash and wash at any time to ensure that hot water is available at any time without waiting.
Myth 6: "Use more hot water and spend more money on heating". Solar water heater, through the use of free and sufficient solar energy resources, let you invest once, long-term benefits, heating hot water without money, do not need to be used in vain. Not using hot water is not only a neglect of your own health and the health of your family, but also a great waste of solar energy resources.
The basic structure of gas boiler water heater is mainly composed of valve assembly, main burner, small fire burner, heat exchanger and safety device. (It also includes flue of flue water heater and strong exhaust device of strong exhaust water heater. The body assembly controls the working procedure of the whole water heater, which includes water valve, air valve, micro switch and igniter. When installing water heater, valves should be installed on intake pipe, outlet pipe and gas pipe.
When using the water heater, open the gas valve and the intake valve first. When the outlet valve is opened, the igniter and the micro switch control the ignition of the small fire first, and then the main fire. Some water heaters have no small fires and can directly ignite the main fire. Gas is burned in the combustion chamber. Heat is heated by the heat exchanger, and hot water is continuously flowing out from the outlet. Turn off the outlet valve and stop the water heater.
