1. If there is a wall-hung boiler at home, is it necessary to add a gas water heater?

　　The wall-hung boiler can not only flexibly control the heating temperature of each room in winter, but also provide users with a large flow of constant temperature sanitary hot water. Compared with gas water heaters, wall-hung boilers have dual functions of bathing and heating. Therefore, there is no need to add a water heater.

　　2. When heating in winter, will the wall-hung boiler work continuously for 24 hours?

　　Basically not, the output power of the wall-hung boiler is selected according to the larger value of the sanitary hot water load and the heating load. Usually, the household's sanitary hot water load is greater than the heating heat load, so at the set indoor temperature, the wall-hung boiler will automatically start and stop according to the set program without human intervention.

　　3. How to draw fresh air and discharge combustion flue gas when the gas wall-hung boiler is working?

　　Wall-hung boilers are generally installed in closed kitchens or balconies. The combustion method is the most advanced balanced combustion. Generally, coaxial double-layer smoke pipes are used. Layer smoke pipe inhaled from outdoors. When the gas wall-hung boiler is working, it draws air and discharges exhaust gas through the independent intake pipe and exhaust pipe. Both have nothing to do with indoor air, so it is safe and reliable.

4. How much gas does the gas wall-hung boiler consume in a month?

　　The air consumption has a certain relationship with the indoor set temperature, outdoor climate conditions, ventilation, building insulation status, and user usage. Therefore, the heating gas consumption varies from household to household, and the gas consumption will vary greatly due to differences in various factors.

　　5. Air conditioners or other electric heaters can also heat, why install a home heating system?

　　The home heating system mainly has the following advantages: a. The indoor temperature is comfortable, there is no noise, and there is no air against the flu during the heating process. b. The cost is low, which can save 30-50% of the cost compared with electric heating. c. Safe and convenient. Reducing electromagnetic radiation in the living environment. d. Not affected by outdoor temperature (many air conditioners have poor heating effect when the temperature is lower than 0°C in winter)

　　6. When should the heating system be installed?

　　The heating system is best designed in sync with the decoration plan. The best construction time is to pre-arrange the pipes before the decoration starts, and at the end of the decoration, install the gas wall-hung boiler, connect the pipelines and each group of radiators, and finally carry out the overall debugging of the system, including airtightness test, ignition test, exhaust and thermal balance adjustment, etc.

　　7. The noise of the wall-hung boiler is a bit loud.

　　There are two reasons. First, there is noise as soon as the machine is turned on, mostly because the dynamic balance of the fan is destroyed and the vibration is caused, and the fan needs to be replaced to eliminate it. Second, there is a whistling-like sound after running for a period of time, which is generally caused by resonance at a specific water temperature and a specific flow rate, Just turn the pump speed down a notch.

　　8. How to operate the wall-hung boiler after a power outage?

　　After a power failure, the gas outlet valve will close by itself, and the gas will also go out. Of course, it is better to close the gas valve yourself, but it is not a big problem even if it is not closed.

　　9. The wall-hung boiler is frequently shut down due to the reduced water pressure of the heating system, and needs to be replenished frequently. How to deal with it?

　　Under normal circumstances, the water pressure in the system should not have a large change, that is, there will be no downtime. If it is frequently shut down, it means that there is a leak in the system, and you should ask professionals to inspect and repair the boiler and heating system.

　　10. Do you need to turn off the boiler when you are not at home during the day?

　　In winter, there is water in the wall-hung boiler or heating system, so the wall-hung boiler must keep water, electricity and gas fully connected to avoid the heating system and the water pump, heat exchanger and other components of the wall-hung boiler from being frozen, thereby causing unnecessary losses. Therefore, before you go out to work, it is recommended to adjust the heating temperature of the wall-hung boiler to the lowest level.
