Oil Boiler Servicing

Annual oil boiler servicing in Sligo cleans your system, checks every component, and helps prevent breakdowns before they happen. Regular servicing reduces oil consumption, extends your boiler's life, and catches small faults early. We service Grant, Firebird, Warmflow and all major oil boiler brands for safe, efficient heating all year.

Oil Boiler Repair

Oil boiler repair in Sligo for boilers that won't fire, keep cutting out, or make strange noises. We diagnose and fix common faults, like failed pumps, blocked nozzles, faulty photocells and control problems, and get your heat and hot water back on. Most repairs are sorted in a single visit.


Electric Boilers

 Electric boiler installation and repair in Sligo for homes without oil access, or as a reliable backup heat source. Electric boilers are compact, quiet, and need no flue or fuel deliveries, which makes them ideal for small properties, apartments, or backup heating, with a lower upfront cost and simple installation.


Back Boiler Removal

Back boiler removal and replacement in Sligo for outdated systems hidden behind fireplaces. Old back boilers are inefficient and often unsafe. We remove the old unit and replace it with a modern oil boiler or heat pump system, sealing the fireplace and removing the old pipework safely and tidily afterwards.

Our oil bills hit €1,600 every few months without stopping. JTR Plumbing and Heating put in our oil boiler in October and we just survived our first winter. Total heating cost for Dec and Jan combined was €210 on our electric bill. I thought the meter was broken. It wasn't. The system just really works.

What I loved most was that they didn't try selling me the costliest setup. They surveyed the house, explained what I actually needed, gave three quotes with different brands. No pressure. The lads doing installation were tidy, professional, explained how it all worked before leaving

My Dad kept nagging me to get a heat pump, and thank god I listened! I used to fret about our ancient oil burner, but the engineer surveyed our place and said a pump would be spot on. Now, our home is roasting all winter, and chills us like AC in summer. It is hands down the top way to slash bills.

I was terrified about our oil boiler replacement but my daughter kept saying get a new upgrade. JTR came out, checked radiators, insulation, and fitted it. They were right. The modern system is warmer than ever and we're saving a fortune.
