Oil Boiler Repairs and Annual Service

An annual boiler service, carried out by a Heat Services Network engineer will ensure that your boiler is functioning properly.

Regular servicing of your boiler will ensure that the boiler is working to the specifications designed by the boiler manufacturer. This will help prolong the life of the boiler as well as reduce the risk of faults and expensive repairs down the line.

A detailed service will include inspection of the pipe work, ventilation, clearances etc. The system is then inspected, cleaned and reassembled. The operation of the boiler functions are then inspected for safe and correct operation.

All boilers should be serviced in accordance with the manufacturer's instructions. In order to have your boiler work to peak efficiency the original manual is necessary. Therefore all engineers have computer access to thousands of boiler manufacturer manuals allowing us to ensure your boiler is working to manufacturer specifications.

Typically when performing an annual boiler service, the Heat Services Network engineers will carryout the following checklist:

• Check for oil leaks from tank and above ground piping/fittings
• Check for significant corrosion on the boiler's outer sheet metal, its cast-iron sections, flue, electrical controls, nearby piping and components.
• Check the draft regulator for free movement
• Check operation of oil shut-off valve
• Check air inlets to boiler room and burner for blockage/size
• Check for cracks/damage to burner refractory
• Clean/adjust spark electrodes
• Clean burner diffuser and air tube
• Check ignition transformer, HT cable and porcelain for cracking/deterioration
• Check operation of draught stabilizer
• Check/clean flame photocell
• Clean boiler gas side heat transfer surfaces.
• Replace burner nozzle
• Adjust burner pressure and diffuser plate to obtain correct flame shape/length
• Check operation of flame failure device
