Nowadays, household gas wall mounted stoves have become a necessary heating device for every household. When purchasing a wall mounted stove, users often care about its purpose, such as whether there is noise during operation.
It is well known that any electrical equipment will produce certain noise during operation. For example, motors in air conditioners, refrigerators, and wall mounted stoves can emit noise during normal operation, but the noise decibels are different. Under normal circumstances, the noise generated by wall mounted furnaces will not affect daily life. If abnormal noise is found in the wall mounted furnace, how to solve it?
Possible sources of noise from Haige wall mounted furnaces
The mechanical noise generated by solid vibration in a gas wall mounted furnace. When the fan rotates, the impeller and casing vibrate, resulting in mechanical noise;
Aerodynamic noise: When eddy currents occur in flowing gases (fuel gas, air, and flue gas), sudden changes in pressure, flow cross-section, or direction, causing airflow disturbances and pressure waves, can generate aerodynamic noise;
Heat exchange noise: If phase transitions occur during partial evaporation of water during heating, vibration changes in the flow state can cause heat exchange noise;
Combustion noise, including laminar and turbulent flame noise and oscillating combustion noise;
Ignition noise, caused by ignition and deflagration;
Backfire noise, the deflagration sound caused by the flame retracting into the fire hole and igniting the combustible mixture in the combustor chamber;
The flameout noise, which occurs when the gas valve is suddenly closed and the flame is extinguished, is a special form of backfire.
Six Reasons for Abnormal Noise in Haige Wall-mounted Stove
Cause 1: The installation of wall mounted furnace is not standardized
When installing a wall mounted furnace, it is not firmly fixed, and the connection between the wall mounted furnace and the wall is not firm. During operation, resonance between the fan and the casing in the wall mounted furnace can occur. After a long time of operation, the noise of the wall mounted furnace will increase. If the use time becomes longer and loosens, it is recommended to contact the brand after-sales service and strengthen the installation of the device.
Cause 2: The fan is dusty or malfunctioning
The wall mounted furnace has been used for a long time, and the dust and impurities on the fan blades affect the rotating balance of the fan, causing mechanical noise. It is also possible that the fastening screws are loose or the fan shaft is eccentric, resulting in noise when the fan is running. Contact professional after-sales personnel for on-site maintenance, disassembly, and cleaning.
Cause 3: Foreign matter or fault in the water pump
If solid particles and impurities in the heating system pipe penetrate into every water passage area inside the pump, it will lead to an increase in the operating noise of the pump. Preventive measures should be taken before installing the wall mounted furnace. A fine filter can be installed at the water inlet of the wall mounted boiler, and foreign matters in the water pump can be cleaned regularly. If major faults such as impeller breakage occur, it is necessary to replace the water pump with a new one.
Cause 4: Ash accumulation at the nozzle of the wall mounted furnace
Gas is ejected from the nozzle at a high speed, resulting in strong disturbances, momentum, mass exchange, and noise due to the ash content of the nozzle, the rapid outlet flow, and the surrounding static air. In this case, professional after-sales service personnel should be contacted to clean the nozzle and gas filter.
Reason 5: Unstable gas pressure
When the combustion of a wall mounted furnace is unstable, the flame will vibrate frequently, leading to oscillation and amplification of the combustion pressure wave in the water tank, forming resonance noise. Contact the gas company to inspect the pressure on site.
Reason 6: Poor water quality or gas accumulation
The accumulated gas or poor water quality in the heating pipeline can cause combustion noise when heated to a higher temperature in the combustion heat exchanger. Clean the filter screen, replace the rotor and flow limiting ring of the water valve, or directly replace the water valve, start and repeatedly discharge the gas in the water circuit.
