Grant, Firebird and oil boilers engineers in Whitnash

Working on Grant, Firebird and oil boilers boilers every week

Plenty of properties around Warwick sit off the gas main and run on oil. Oil boilers need a different discipline to gas: a burner strip, nozzle change, electrode set and combustion test every year, not a quick look and a sticker. Serving Whitnash and the surrounding Warwickshire area.

We work on Grant Vortex and VortexBlue, Firebird Envirogreen, Warmflow Agentis and the Worcester Danesmoor and Heatslave ranges, internal and external models.

Oil boilers that are not serviced annually soot up, lose efficiency and eventually lock out. An annual OFTEC service keeps the combustion figures right and catches tank, filter and fire valve issues before they leave you cold.

We also handle oil boiler replacement, tank work and the switch to a modern condensing oil boiler where an old non-condensing appliance is finally finished.

Common signs to look out for

  • OFTEC oil boiler servicing with combustion test
  • Burner strip, nozzle and electrode replacement
  • Grant Vortex and VortexBlue repairs
  • Firebird, Warmflow and Danesmoor repairs
  • Oil boiler lockouts and no-fire faults
  • Oil boiler replacement and tank work

Servicing and warranty

Keeping your Grant, Firebird and oil boilers warranty valid

Grant, Firebird and oil boilers warranties require an annual service by a registered engineer with the service record completed. Miss a year and the cover can be refused when you most need it.

We follow the manufacturer's own service schedule, test combustion with a calibrated analyser and leave a written record every visit, which is also the paperwork a buyer's surveyor will ask for later.

For landlords we combine the Grant, Firebird and oil boilers service with the CP12 gas safety check on a single visit and email both documents the same day.

Answers

Frequently asked questions

What Whitnash homeowners ask us about Grant, Firebird and oil boilers boilers.

Yes. Oil work is OFTEC rather than Gas Safe, and we hold both, so we can look after gas and oil properties equally.

Burner removed and stripped, nozzle replaced, electrodes checked and set, photocell cleaned, filters changed, combustion tested with a calibrated analyser and the results recorded.

Every twelve months without exception. Oil boilers soot up in a way gas boilers do not, and a missed service shows up as lost efficiency and eventually a lockout.

Whether there is oil in the tank, whether the fire valve is open, and whether the filter is clogged. Press the reset once. If it locks out again, leave it and call us.

Yes. We install condensing oil boilers from Grant, Firebird, Warmflow and Worcester, internal or external, and handle the tank and pipework side too.
