Proper configuration ensures the system runs efficiently, lowering energy consumption and operating costs.

Maintaining Boilers and Heating Systems

Routine maintenance keeps heating systems running safely and efficiently. Key tasks include:

  • Cleaning heat exchangers, burners, and flues
  • Inspecting components for wear, corrosion, or failure
  • Testing for performance and system efficiency
  • Checking safety devices such as pressure valves and ventilation
  • Lubricating moving parts to reduce wear

These checks help prevent breakdowns and ensure the system meets safety standards.

Diagnosing and Repairing Faults

Heating engineers use specialist tools to diagnose issues and carry out repairs. Common faults include:

  • Low heat output
  • Leaks or pressure problems
