Treatment of common problems of wall hanging furnace
Failure analysis of wall mounted boiler: the safety of smoke exhaust, the decrease of sanitary hot water, the noise of heating, the sound of water flow and other common failure treatment methods of wall mounted boiler.
How to drain the water when cleaning the filter: close the cold water inlet valve, open the water filling valve, open the tap of sanitary hot water, and the heating water in the furnace can be discharged. Reverse operation can refill water. Just turn it on. The drainage of radiator can only use the running wind of radiator.
The reason why the hot water volume of the wall mounted boiler becomes smaller: the filter screen of the tap is blocked or the filter screen of the cold water inlet is blocked. Remove the bellows at the cold water inlet and you can see it. It can be recovered after cleaning.
The heating of the wall mounted boiler has noise and the water heating is slow: the filter screen at the inlet and outlet of the heating of the wall mounted boiler may be blocked, the bellows may be removed for cleaning, or the heating pipeline may be blocked.
Smoke exhaust safety of wall hanging furnace: the smoke pipe of wall hanging furnace is concentric double pipe, the inner pipe is smoke exhaust, the outer pipe is air inlet, and it is connected with the sealed room, but completely isolated from the room. All brands of wall mounted boilers are forced smoke exhaust (with fan) balanced (with air pressure switch), so smoke exhaust and air intake are carried out outdoors, which will not consume indoor air, and the safety is guaranteed. The explosion accidents in recent years are all caused by the leakage of natural gas hose, and there is no report of furnace explosion.
Common fault inspection of wall mounted furnace
As the wall mounted furnace is a kind of household heating equipment with high technical content, which integrates fan and water pump, combustion equipment, heat exchange equipment, electrical automatic control and complex mechanical structure. In addition, it is also closely related to heating and heating water pipe system. Therefore, it is necessary to correctly judge the cause of the failure according to the working logic process of the wall mounted furnace in order to correctly analyze and solve the problem.
In each debugging and fault judgment, the following necessary operation steps should be carried out first.
① Check the gas system, including gas type, gas composition, gas calorific value, gas supply pressure, gas supply flow, gas pipeline, gas meter, etc.
② Check the heating system, including heating area, heating type, heating area, heating load, room design temperature and building conditions.
③ Check the water supply system, including water supply pressure, water supply flow, heating pipes and valves, heating pipes and valves.
④ Check the power supply.
⑤ Check the exhaust condition of wall mounted furnace.
