Where’s the job?

Overview

• Carry out regular cleaning, inspection and servicing of biomass boilers to ensure optimal combustion and efficiency.

• Skill level: 4 / 5 (requires a good understanding of combustion systems, fuel handling, and safety procedures).

• Typical duration: 1 – 2 days for a thorough maintenance and minor repair work.

Safety First

• Always isolate the power supply and allow the boiler to cool completely before beginning work.

• Wear appropriate PPE including gloves, safety glasses and sturdy footwear.

• Follow manufacturer guidelines and local regulations while working with fuel systems and combustion apparatus.

• Ensure proper ventilation of the area to avoid exposure to residual combustion gases.

Tools & Materials

Step-by-Step

1. Switch off the boiler and disconnect the power supply. Allow it to cool completely before commencing any work.

2. Remove accumulated ash and soot from the combustion chamber and ash pan using an ash vacuum or brush.

3. Inspect the feed mechanism, fuel conveyors and storage for any signs of wear or blockages.

4. Examine the combustion chamber, flue and seals for cracks, corrosion or build-up that could impair efficiency.

5. Test sensors, water circulation and pressure relief valves using a multimeter to ensure proper operation.

6. Replace any worn components, lubricate moving parts and tighten fittings as required.

7. Restart the boiler and monitor its operation closely for any irregularities.

Completion Checks

• Combustion efficiency is restored and fuel burns cleanly without excess residue.

• All safety and sensor tests show normal operation with no error indicators.

• There are no fuel blockages or leaks, and the ash pan remains clear.

• All components are secure, and the boiler is ready for regular operation.

When to Call a Pro Instead

If significant faults, persistent error codes, structural issues or complex electrical faults are detected, consult a specialist in biomass boiler maintenance to ensure safety, compliance and warranty protection.
