Keep your home safe, warm and efficient—book a professional oil boiler service today.
Serving Shannon, Ennis, Newmarket-on-Fergus, Sixmilebridge, Bunratty, Clarecastle, Quin, Cratloe, and Limerick City.
Local winters in Clare and Limerick are damp, windy, and unforgiving—your boiler needs to be ready. With an annual service, you burn less oil, cut running costs, and avoid those sudden breakdowns on freezing nights.
Choosing a local technician means faster response and the right parts on the van for Firebird, Grant, Warmflow and Riello boilers common in Shannon, Ennis, and nearby towns. That’s why so many of your neighbours already trust us every year.
Why service your oil boiler every 12 months?
Improve safety and reliability – reduce the risk of dangerous soot build-up, carbon monoxide leaks, or sudden lockouts in the middle of winter.
Lower fuel consumption and emissions – a clean burner and the right nozzle angle mean up to 10% savings on oil use and a greener home.
Catch small issues early – worn hoses, a weak capacitor, or a blocked baffle are cheap to fix now but expensive if left until breakdown.
Protect your warranty and insurance – most manufacturers and insurers require annual service records.
Extend the life of your boiler – regular cleaning and pressure checks prevent long-term damage and add years of service life.
Keep hot water and heating consistent – no more cold showers or radiators that only half-heat when the system is clogged.
Peace of mind – you get a dated service sticker, a full report, and a reminder for next year so you never have to worry about forgetting.

| Combi (oil) | Mainly indoor | Hot‑water plate exchanger care; scale prevention is critical |
| System | Indoor | Integrated expansion vessel and safety set |
| Boilerhouse / utility | Indoor utility space | Easy access for maintenance; check ventilation |

Report covers: flue, burner, oil line & hoses, safety controls, electrical checks, circulation checks, and (where applicable) flue‑gas readings & efficiency.
Technical note (for homeowners who like the details)
First of all, nozzle flow (GPH) and spray angle are matched to your specific burner and boiler (for example, Riello RDB on Firebird, Grant, or Warmflow).
In addition, the pump pressure is set to manufacturer specification and its stability is verified.
Next, we check the electrode gap and position, along with the photocell, ignition transformer, capacitor, and HV leads.
At the same time, the combustion chamber is inspected and vacuum-cleaned, and the baffles are thoroughly cleaned.
For safety, all control thermostats are tested and electrical earth continuity checks are carried out.
Finally, a flue-gas analysis is performed (where applicable) to optimise efficiency.
Optional upgrade: a full burner strip-down and rebuild can be completed, including a deep clean, new seals, and full recalibration.

Before & After – See the Difference
A serviced boiler isn’t just cleaner inside—it runs quieter, burns oil more efficiently, and leaves no black soot or smoke. Our photos show the clear difference between a neglected burner and one that’s been properly cleaned, calibrated, and fitted with a new nozzle and filter. This way you can see exactly what our annual service delivers.
Common Oil Boiler Problems & How We Fix Them
