Winter Heating Equipment Maintenance Guide: Complete Wall-mounted Boiler Care Instructions

As winter approaches, heating equipment usage is entering its peak season. To ensure the efficient and safe operation of wall-mounted boilers, Vanka, a professional heating equipment manufacturer, today released a winter maintenance guide to help users properly maintain their equipment.

I. Essential Pre-Heating Season Checks

1. System Pressure Check

   • Ensure the pressure gauge reads within the normal range of 1–1.5 bar.

   • Replenish water if pressure is too low; release water if pressure is too high.

2. Gas Pipeline Inspection

   • Use soapy water to check for gas leaks at connection points.

   • Inspect gas lines for aging or cracking.

3. Ventilation System Check

   • Confirm the exhaust pipe is securely installed and unobstructed.

   • Check the air intake for dust accumulation.

II. Key Maintenance During Operation

1. Recommended Temperature Settings

   • Heating temperature should be set between 60–65°C.

   • Domestic hot water temperature is ideally set at 40–45°C.

2. Regular Cleaning and Maintenance

   • Professional cleaning of the heat exchanger every two years.

   • Remove carbon buildup from the burner annually.

   • Clean the water inlet filter monthly.

3. Freeze Protection Measures

   • Ensure the power supply remains on.

   • Activate freeze protection mode when ambient temperature drops below 5°C.

   • Drain the system if away for an extended period.

III. Troubleshooting Common Issues

1. Continuous Pressure Drop

   • Check the heating system for water leaks.

   • Inspect the pressure gauge for malfunctions.

2. Ignition Failure

   • Verify that the gas valve is open.

   • Ensure the power supply is connected properly.

3. Unusual Noises

   • May be caused by air trapped in the pump; bleeding may be required.

   • Scaling in the heat exchanger can also cause abnormal sounds.
