Daily use and safety maintenance of household wall-hung boilers
1. Installation of gas pipelines
The connection between wall-hung boilers and gas pipelines must be installed and debugged by trained professionals. The key point is to use gas pipelines that meet safety requirements and secure them with clamps to prevent them from falling off. It is strictly prohibited to seal the gas meter.
2. Leakage inspection of the gas passage
extends from the gas meter interface to the wall-mounted boiler gas valve and the fire exhaust interface. Any connected interface must first undergo an air tightness test and can be used only after passing it.
The simplest and most feasible daily method is: before the wall-hung boiler is powered off or running, open all gas valves , apply soapy water (or diluted dish soap) to the interfaces, and observe for 3-5 minutes. If no bubbles are generated, it means there is no air leakage. This method is recommended to be repeated every two months. When you smell gas, get it checked immediately. If conditions permit, you can use a handheld flammable gas alarm to detect each gas interface or install an gas alarm .
3. Check and replace
According to the quality of the gas hose, replace it regularly to prevent the danger of gas leakage caused by aging and cracking of the hose.
4. Handling of unexpected situations
If you smell gas smell indoors, you should first close all gas valves, and do not turn on or off all household appliances or power switches , and do not use mobile phones or landlines. Then open the doors and windows to allow adequate ventilation. Only when you can no longer smell the gas smell can you turn off all electrical switches. Notify gas-related professionals outside to come to your home for inspection and troubleshooting.
Safety and maintenance issues
The installation of a household wall-mounted boiler provides convenience for our daily heating and hot water use. What safety matters should we pay attention to when using home wall-mounted boilers?
1. The bottom, hot water pipe and smoke are relatively hot during use. Please do not touch them during use to prevent burns.
2. The pressure must not be too high. 1.2 to 1.5 is the most appropriate range. If it is exceeded, the service life of the sealing parts will be reduced. If the pressure is too small, it will not start. The solution is to open the relief valve to release water and open the water inlet switch to add water.
3. Before use, its ventilation system needs to be fully inspected to prevent blockage and malfunction during use.
4. Bathing, living, and flammable and explosive materials are not allowed in the room where the wall-hung boiler is placed.
5. Purchase wall-hung boilers through regular channels. When purchasing, go to regular stores to purchase wall-hung boilers. Product quality, use safety, and after-sales service are more guaranteed.
6. As long as the water pressure in the wall-hung boiler is maintained between 0.5-1.5b, it will not affect the normal use of the wall-hung boiler at all. If the water pressure is lower than 0.5b, the domestic hot water may become hot and cold or fail to start normally.
7. Do regular maintenance and upkeep work. Some household wall-hung boilers are never cleaned or maintained during continuous use for multiple heating seasons. Scale and soot cause the wall-hung boiler to become gas-consuming, causing hot and cold water to alternately become hot and cold. To maintain the efficiency of your wall-hung boiler, it should be cleaned and maintained regularly. Gas savings can be as high as 25%. Regular maintenance every 1-2 years can effectively extend the service life of the wall-mounted boiler.
