3. Step-by-step troubleshooting guide
1.basic check: First, confirm that the power connection of the wall-mounted boiler is normal, the gas supply is sufficient, and the water pressure is within a reasonable range (1-1.5bar).
2.Temperature setting: Check the temperature setting on the control panel. In winter, it is recommended that the domestic hot water temperature be set at 55-60°C, and the heating water temperature be adjusted according to indoor needs.
3.Observe running status: Pay attention to whether the wall-hung boiler is ignited successfully and whether the combustion flame is blue (yellow flame may indicate insufficient combustion).
4.Check waterways: Check whether each valve is fully open and whether the pipeline is blocked. You can test the water flow pressure by releasing water.
5.Professional maintenance: If the above steps are ineffective, it is recommended to contact the manufacturer’s after-sales service or professional maintenance personnel to avoid disassembling the device yourself.
4. User FAQs
Q: The wall-mounted boiler starts frequently but the water is not hot?
A: It may be that the gas pressure is unstable or the heat exchanger is severely fouled, which requires professional testing.
Q: Heating is normal but domestic hot water is not hot?
A: Focus on checking whether the three-way valve is working properly. There may be a mode switching failure.
Q: Does the outlet water temperature of the newly installed wall-hung boiler not meet the standard?
A: It may be that the pipes were connected incorrectly during installation or the system was not properly vented. Contact the installer for review.
5. Preventive maintenance suggestions
1. Perform professional maintenance every year before the heating season and clean the heat exchanger and filter.
2. Check the water pressure regularly to avoid dry burning damage due to lack of water.
3. When not in use for a long time, the water stored in the system should be drained to prevent freezing and cracking.
4. Use original parts to replace them to ensure compatibility and safety.
Through the above systematic analysis and solutions, we hope to help you quickly solve the problem of wall-mounted boiler water not being hot. If the problem persists, be sure to contact professional maintenance personnel to ensure safe use.
