How to clean a wall-hung boiler
As winter approaches, wall-mounted boilers are important equipment for home heating, and their cleaning and maintenance have become a hot topic recently. Many users are concerned about how to properly clean wall-mounted boilers to improve efficiency and extend service life. The following is a summary of the key points on wall-mounted boiler cleaning in the past 10 days across the Internet. The content is structured and presented to help you easily master cleaning techniques.
1. The necessity of cleaning the wall-hung boiler
Regular cleaning of wall-hung boilers can effectively avoid the following problems:
| Question type | Specific performance |
|---|---|
| Thermal efficiency decreases | Heating speed slows down and energy consumption increases |
| Shortened equipment life | Internal scale buildup causes corrosion of components |
| safety hazard | Insufficient combustion may cause carbon monoxide leaks |
2. Preparation work before cleaning
| steps | Operating Instructions |
|---|---|
| Power and gas outage | Turn off the power and gas valves to ensure safety |
| Tool preparation | Soft brush, special cleaning agent, rubber gloves, container |
| Check equipment | Record the current operating parameters of the wall-hung boiler (such as pressure value) |
3. Step-by-step cleaning guide
1. External cleaning
Use a slightly damp rag to wipe the fuselage to avoid water seeping into the circuit board area. The vents need to be cleaned with a vacuum cleaner.
2. Burner cleaning
| parts | Cleaning method |
|---|---|
| Fire steak | Use a copper brush to remove carbon deposits. Do not use steel wire balls. |
| nozzle | Special needle is used to clear the hole and keep the hole diameter consistent. |
3. Deep cleaning of heat exchanger
This is the core part of cleaning:
| Scale type | Solutions |
|---|---|
| light scale | Citric acid solution circulation flushing (concentration 5%) |
| severe scaling | Professional descaling agent soaking + high pressure water gun cleaning |
4. Precautions after cleaning
| Check items | Standard requirements |
|---|---|
| Sealing | There is no leakage in each interface and the pressure gauge is stable. |
| combustion state | The flame is blue and there is no deflagration. |
| drainage system | The drain valve is closed tightly and the drain pipe is clear |
5. Comparison of cleaning points of different brands
| Brand | special design | Cleaning recommendations |
|---|---|---|
| power | Secondary heat exchanger | Stainless steel heat exchange fins need to be removed and cleaned separately |
| Bosch | Plate heat exchanger | Do not use acidic cleaning agents |
| Rinnai | Staged combustion technology | Focus on cleaning the gas proportional valve |
6. Reference data for professional cleaning services
| Service type | market price | Cycle suggestions |
|---|---|---|
| Basic maintenance | 200-300 yuan | 1 time per year |
| deep cleaning | 500-800 yuan | Once every 3 years |
| chemical cleaning | More than 1,000 yuan | Determined based on water quality testing |
Warm reminder:
1. For first-time cleaning, it is recommended to contact the manufacturer’s after-sales service and observe and learn the professional operating procedures.
2. Northern areas with hard water should shorten the cleaning cycle (it is recommended to deep clean once every 2 years)
3. It takes half an hour to exhaust air for the first operation after cleaning, and observe the working status of the equipment.
Through systematic cleaning and maintenance, the wall-mounted boiler can maintain more than 90% thermal efficiency and extend its service life by 3-5 years on average. It is recommended that users establish cleaning files to record the specific content of each maintenance and changes in equipment parameters to provide data support for long-term maintenance.
