Coverage
Bray, Wicklow, S. Dublin

Plenty of homes around North Wicklow are still on oil, and a modern condensing oil boiler is a big step up on an old cast iron unit for both comfort and running costs. We survey the house, size the boiler correctly, handle the tank, fire valve and flue properly, and commission the boiler with a combustion analyser so it runs at its rated efficiency.

  • Free survey and fixed written quote
  • Internal and external condensing oil boilers supplied and fitted
  • Oil tanks, fire valves, filters and flue work handled
  • System flushed and magnetic filter fitted
  • Commissioned with a combustion analyser and a written record

Oil Boiler Installation: common questions

Can you replace an oil boiler with an external one?
Yes. External condensing oil boilers are common where there is no suitable indoor space. We handle the base, pipework, flue and controls.
Is there a grant for replacing an oil boiler?
Not for a like-for-like oil boiler replacement. Grants apply if you switch to a heat pump, or for insulation and heating controls carried out separately.
How often should an oil boiler be serviced?
Annually. Oil boilers gather soot and the nozzle and filter need changing, so skipping a year shows up quickly in efficiency and reliability.
How long does an oil boiler installation take?
A like-for-like replacement is normally a day. Moving the boiler outside, laying a new base or re-running the oil line and flue can push it into a second day, and we will tell you which before we start.
Can you take out an old back boiler behind the fire?
Yes. Back boilers are still common in older homes around Bray and Greystones. We remove the back boiler, cap off safely and move the heating over to a modern condensing boiler, then flush the system so the old sludge does not follow you to the new one.
