Engineer servicing an oil boiler burner: Firebird oil boiler service in Northern Ireland

Who makes Firebird boilers

Firebird is an Irish heating manufacturer headquartered in County Cork, with more than 40 years making oil boilers. It has manufacturing sites in Ireland and the UK, including Northern Ireland, and today its range covers condensing oil boilers alongside heat pumps and solar products.

Because Firebird builds for Irish homes, its boilers are a familiar sight in Northern Ireland’s oil-heated houses, especially rural ones where the boiler sits outside or in a boiler house beside the tank.

  • Enviromax: the main condensing oil range, in kitchen, utility, boiler house and external formats, plus combi versions.
  • Envirogreen: an earlier range, still in many homes.
  • Heatpac: the external, weatherproof versions designed to sit outside the house.

Older non-condensing Firebird boilers are serviced in the same way. If parts for a very old model are hard to source, we will tell you on the day.

Every Firebird service is carried out by an OFTEC registered technician and follows the service instructions for your model. It typically includes:

  • replacing the burner nozzle and fuel filter element;
  • cleaning the combustion chamber and heat exchanger passes;
  • checking the electrodes and cleaning the photocell;
  • checking and clearing the condensate trap on condensing models;
  • setting the burner with a combustion analyser and recording CO2, smoke, flue temperature and efficiency;
  • checking seals, flue and controls;
  • a visual check of the oil tank, fuel line and fire valve;
  • an OFTEC CD/11 service record left with you.

External Heatpac models take a little longer when the casing and burner compartment need cleaning out. The full checklist is in our what a boiler service includes guide.

Like most manufacturers, Firebird generally ties its guarantee to an annual service by a registered technician, with a record kept each year. Conditions differ by model and by date of installation, so check your guarantee terms before assuming you are covered.

If you have lost track of when your boiler was last serviced, start the record again with a service now and keep the CD/11 each year.

Oil boilers fail in fairly predictable ways, and Firebird boilers are no different:

  • Lockout. The burner fails to light and the reset light comes on. Check you have oil first, then read oil boiler not firing.
  • Smoke, soot or smell. Usually the burner needs setting up or the nozzle is worn. See oil boiler smoke or smell.
  • Condensate blockage. External models in hard frost can block the condensate pipe and lock out.
  • Noisy firing. A rumble or bang on start-up is a combustion fault that needs an engineer.

Our Firebird boiler problems guide goes through these in more detail. We do not publish Firebird fault code tables, because they vary between ranges and controls. Your manual is the reference, and our technician will find the cause on site.

A Firebird oil boiler service is £89, fixed and including VAT, with an OFTEC CD/11 service record.
Firebird is an Irish heating company headquartered in County Cork, with manufacturing sites in Ireland and the UK.
Most are the same as any oil boiler: lockouts from fuel supply or a worn nozzle, smoke or smells from poor combustion, and condensate blockages on condensing models. Our Firebird problems guide covers each one and what you can safely check.
Once a year, ideally before the heating season. Oil boilers build up soot and wear nozzles faster than gas boilers, so a missed year shows up in fuel use and reliability.

Useful next steps.

Your boiler has a spec. We work to it.
