1、 Building adaptive working conditions: creating an "ideal residence"

1. Water quality management plan

In areas with excessive hardness (>120mg/L), it is recommended to install a pre installed water softener

Add specialized scale inhibitor (1:1000 ratio) every month

Implement full water maintenance after the end of the winter heating season (maintain the system water level until the next use)

2. Environmental parameter control

Installation location requirements: Good ventilation (with 50cm space reserved in front and back), dry environment (humidity<70% RH)

• Power configuration: Dedicated line power supply (dedicated line load ≥ 3kW), using flame-retardant sockets (IP20 protection level)

Anti freezing measures: In winter, the water pressure is maintained in the range of 0.1-0.3 MPa, and anti backflow air caps are installed on the smoke pipes

2、 Standardize operating procedures: avoid "excessive consumption"

1. Start stop operation specifications

Cold start suggestion: Run the circulating water pump for 30 seconds before the first ignition

Hot start interval: Preheat for 3 minutes after shutdown for more than 2 hours

Taboo operation: It is strictly prohibited to forcefully cut off power or close gas valves while the equipment is running

2. Intelligent temperature control strategy

Recommend using a constant temperature controller with an accuracy of ± 1 ℃

Night sleep mode setting gradient heating (such as adjusting from 18 ℃ to 22 ℃ in different time periods)

• Set room temperature compensation function, automatically adjust output power according to outdoor temperature difference

3. Key points of seasonal maintenance

Winter antifreeze: Keep the system water pressure ≥ 0.1MPa when going out for a long time

• Overhaul in summer: check the tightness of the smoke pipe interface after a rainstorm to ensure smooth drainage of condensate

• Filter maintenance: Clean the pre filter screen (Y-shaped filter) once every quarter

3、 Periodic maintenance plan: preventive maintenance system

1. Daily self inspection checklist

• Weekly: Observe fluctuations in gas pressure gauge readings (normal range ± 5%)

• Monthly: Test ignition success rate and flame color (preferably blue)

• Quarterly: Check if the water pressure is stable (cold state 1 bar ± 0.1 bar)

2. Professional maintenance nodes

Half a year: Heat exchanger flaw detection (no cracks/corrosion)

1 year: Gas valve group sealing test (leakage rate<0.03%)

2 years: Dynamic balance correction of water pump impeller (vibration value ≤ 4.5mm/s)

3 years: Thermal efficiency testing (standard value ≥ 96%, national standard level 1 energy efficiency)

3. Replacement cycle of key components

Burner: It is recommended to replace the ceramic fire cover every 8-10 years

Heat exchanger: Replace copper pipes/stainless steel plates within 3-8 years based on water quality conditions

Water pump: Immediately inspect and repair in case of abnormal noise or decreased flow rate

Identification of equipment health warning signals

When the following situations occur, professional personnel should be contacted in a timely manner:

❗ Ignition failed more than 3 times

❗ Abnormal combustion noise (explosion/hissing sound)

❗ Water outlet temperature fluctuation>5 ℃

❗ The ECO indicator light flashes frequently

By constructing a three-dimensional management system that adapts to working conditions (accounting for 30% of the life influencing factors), standardizes operating procedures (accounting for 40%), and implements periodic maintenance (accounting for 30%), the comprehensive service life of wall mounted boilers can be extended to 12-18 years. It is recommended to entrust a professional organization to conduct thermal efficiency testing every 2 years. When the seasonal energy rate is below 85%, timely deep maintenance or equipment updates should be carried out. Scientific maintenance is not only related to economic costs, but also an important measure to ensure home safety.
