With the decrease in winter temperatures, wall mounted boilers have become the core equipment for heating and hot water supply in many households. Correctly mastering the use of wall mounted boilers can not only ensure heating effectiveness, but also avoid safety hazards. For most families, the safe operation of wall mounted boilers is directly related to their living safety. Therefore, it is crucial to understand the key points of safe use of wall mounted boilers. Below are detailed precautions for the entire process of safe use of wall mounted boilers.

1、 Before using the wall mounted boiler: do a basic inspection and preparation

Before starting the wall mounted boiler, a series of basic checks need to be completed to ensure that the equipment is in a safe initial state, which is a key step in avoiding subsequent failures.

1. Appearance and connection inspection

Firstly, observe whether there is any obvious damage to the wall mounted boiler body, such as deformation of the shell, exposed wiring, etc. If such problems exist, stop using it immediately and contact professional personnel for maintenance. Next, focus on checking the connection interface between the gas pipeline, water pipe, and wall mounted boiler to confirm that there is no looseness, air leakage, or water leakage at the interface. Soap water can be used to coat the interface. If bubbles appear, it indicates that there is a gas leak, and the gas main valve needs to be closed and ventilated before treatment.

2. Water pressure and power supply inspection

The operation of wall mounted boilers relies on stable water pressure. Before use, it is necessary to check the equipment water pressure gauge to ensure that the water pressure is between 0.1-0.15 MPa. If the water pressure is too low, it can be slowly replenished through the wall mounted boiler water replenishment valve to avoid equipment damage caused by sudden increases in water pressure; If the water pressure is too high, it is necessary to open the drain valve to release some of the water. At the same time, check whether the power connection of the wall mounted boiler is secure, whether the power cord is aged or damaged, and ensure stable power supply before turning on the equipment.

2、 During the use of wall mounted boilers: follow standard operation and daily maintenance

When using wall mounted boilers in daily life, standardized operating habits and regular maintenance can effectively extend equipment life and reduce safety risks. The following points need to be focused on.

1. Temperature setting and operating mode

Reasonably set the temperature of the wall mounted boiler according to actual needs. It is recommended to control the heating temperature at 18-22 ℃ and the temperature of the domestic hot water at 40-50 ℃ to avoid energy waste or equipment overload caused by excessive temperature. At the same time, pay attention to distinguishing between heating mode and hot water mode. Some wall mounted boilers have automatic switching function. When using, it is necessary to confirm that the mode selection is correct to prevent insufficient heating or abnormal hot water supply.

2. Ventilation and environmental maintenance

During the operation of wall mounted boilers, oxygen is consumed and exhaust gas is generated. Therefore, the space where wall mounted boilers are installed needs to maintain good ventilation to avoid oxygen deficiency or exhaust gas accumulation caused by a closed environment. It is strictly prohibited to stack flammable and explosive materials such as cardboard boxes, paint, etc. around the wall mounted boiler. At the same time, ensure that there is no obstruction around the equipment and reserve sufficient maintenance space for daily inspection and maintenance.

3. Regular cleaning and component inspection

Clean the filter screen of the wall mounted boiler every week to prevent impurities from blocking the water flow and heat exchange efficiency; Check the smoke exhaust pipes every 3-6 months to ensure tight and undamaged connections and prevent exhaust gas leakage. In addition, if there is abnormal noise, odor or frequent start stop of the wall mounted boiler, it should be stopped immediately and professional maintenance personnel should be contacted to troubleshoot. Do not disassemble the equipment by yourself.

3、 Abnormal situation of wall mounted boiler: timely handling and emergency measures

Even with proper daily maintenance, wall mounted boilers may still experience sudden abnormalities. Mastering the correct emergency response methods can minimize safety risks to the greatest extent possible.

1. Gas leakage treatment

If you smell a gas odor, immediately turn off the power supply and gas main valve of the wall mounted boiler, open the indoor doors and windows for ventilation, and strictly prohibit turning on or off any electrical appliances (including lights, exhaust fans) and using open flames to avoid generating electrical sparks and causing danger. After a period of ventilation, contact the gas company or professional personnel to come and inspect the leakage point. After the fault is eliminated and confirmed to be safe, the wall mounted boiler can be restarted.

2. Water shortage and overheating protection

When the wall mounted boiler displays a water shortage fault code, the equipment needs to be shut down first. After cooling, check the water pressure and replenish water. If the fault still persists after replenishing water, it may be due to water blockage or water pump failure, and professional personnel are needed for maintenance. If the device experiences overheating protection shutdown, the power should be turned off first, and the heat dissipation and circulating water pump should be checked for proper operation. After troubleshooting, the device should be restarted to avoid damage caused by forced startup.

4、 Long term shutdown of wall mounted boilers: take good care of protection and maintenance

During summer or long-term outdoor activities, wall mounted boilers need to be properly maintained to prevent component corrosion or damage, and to prepare for future use.

Before long-term shutdown, it is necessary to turn off the gas main valve and power supply, drain the accumulated water inside the wall mounted boiler and pipelines, and avoid low-temperature freezing cracking or scale growth. Simultaneously clean the equipment casing and internal components, apply rust inhibitor to areas prone to rusting, and finally cover the wall mounted boiler with a dust cover to prevent dust from entering. If the downtime exceeds six months, it is recommended to run the equipment for 10-15 minutes every three months to ensure that the components are in normal working condition and avoid functional failure caused by long-term idle.

Winter heating cannot be achieved without the stable operation of wall mounted boilers, and safety is always the primary prerequisite for using wall mounted boilers. By mastering the correct usage methods, performing daily maintenance and emergency response, wall mounted boilers can not only provide continuous warmth for families, but also safeguard the living safety of the entire family. I hope every user can pay attention to the safe use of wall mounted boilers, and let warmth and safety accompany the entire heating season.
