Gas Boiler Replacement, Repair & Servicing - RGI Registered

RGI Registered Gas Boiler Experts

Gas boilers demand a higher level of qualification and care than any other heating system. In Ireland, only an RGI Registered Gas Installer is legally permitted to work on gas appliances - and for good reason. Incorrect gas work can lead to carbon monoxide poisoning, gas leaks, and fire. When you call us for gas boiler work, you can be confident that every job is carried out by a qualified, RGI registered engineer to the highest safety standards.

We provide a full range of gas boiler services for homeowners across Athlone, Westmeath, and the Midlands, covering annual servicing, breakdown repair, gas safety inspections, and complete boiler replacement.

Annual Gas Boiler Servicing

Why Service Your Gas Boiler Every Year?

Annual servicing is essential for three reasons: safety, efficiency, and reliability. A properly serviced gas boiler runs cleanly and efficiently, keeping your fuel bills low and your family safe. It also reduces the risk of unexpected breakdowns during the coldest months of the year. We explain the full case for regular maintenance in our article on why an annual boiler service is essential.

Most boiler manufacturers require annual servicing as a condition of their warranty. Missing a service can void your warranty, leaving you exposed to the full cost of any parts or repairs.

What Our Gas Boiler Service Includes

• Flue gas analysis - using a calibrated flue gas analyser, we measure combustion efficiency, CO levels, and flue temperature. These readings tell us whether the boiler is burning gas safely and efficiently.
• Heat exchanger inspection - we check for cracks, corrosion, and blockages that could impair performance or pose a safety risk.
• Burner and electrode check - cleaned and adjusted for optimal ignition and flame quality.
• Gas pressure verification - we test both the inlet gas pressure and the burner operating pressure.
• Controls and safety devices - thermostat, overheat cut-out, flame detection, and gas valve operation are all tested.
• Carbon monoxide testing - we test the flue and surrounding area for carbon monoxide to ensure there is no leak.
• Visual inspection - the boiler casing, flue terminal, condensate drain, and ventilation are all checked.

On completion, we issue a service report and, where applicable, a gas safety certificate confirming your boiler is safe to operate.

Gas Boiler Breakdown Repair

Gas boiler breakdowns are not just inconvenient - they can be a safety concern. If you smell gas, hear unusual noises, or your boiler repeatedly locks out, do not attempt to fix it yourself. Turn off the boiler and call a qualified RGI registered engineer.

Common Gas Boiler Faults

• Boiler not firing or igniting - could be a faulty ignition electrode, gas valve issue, or PCB failure.
• Boiler locking out repeatedly - often caused by a blocked condensate pipe (common in cold weather), low water pressure, or a faulty sensor.
• No hot water but heating works - typically a diverter valve fault in combi boilers.
• Radiators cold but boiler running - could indicate a pump failure, airlock, or system sludge.
• Leaking from the boiler - pressure relief valve discharge, internal seal failure, or cracked heat exchanger.
• Error codes on the display - modern boilers display fault codes that help us diagnose the problem quickly.

We carry a wide range of gas boiler parts on our van and can resolve most faults on the first visit. For less common parts, we source and fit replacements as quickly as possible.

New Gas Boiler Installation

Is It Time for a New Gas Boiler?

If your gas boiler is over 12 to 15 years old, breaking down frequently, or running inefficiently, a replacement will save you money in the long term. Older non-condensing boilers typically operate at 60-75% efficiency. A modern condensing gas boiler achieves 90-94% efficiency, meaning you get significantly more heat from every unit of gas.

Our Installation Process

1. Home survey - we assess your property, current system, and heating requirements to recommend the right boiler size and type.
2. Quotation - a clear, itemised quote with no hidden costs.
3. Installation - removal of the old boiler, fitting the new unit, connecting gas, water, and electrics, and routing the flue.
4. System commissioning - the boiler is fired up, tested, and calibrated. We set the controls, check the gas pressure, and run a full flue gas analysis.
5. Handover - we walk you through the controls, set your heating schedule, and register the manufacturer’s warranty.
6. Gas safety certificate - issued on completion, confirming the installation meets all regulatory requirements.

Improving Your BER Rating

Upgrading to a modern condensing gas boiler can improve your home’s BER rating (Building Energy Rating) by one or two grades. A better BER rating increases your property value and may qualify you for energy grants.

Gas Safety Inspections

We carry out standalone gas safety inspections for homeowners, landlords, and property managers. A gas safety inspection covers all gas appliances in the property - boiler, cooker, gas fire - and checks for carbon monoxide leaks, flue integrity, ventilation adequacy, and gas supply safety.

Landlords in Ireland have a legal duty to ensure gas appliances in rental properties are safe. We provide gas safety certificates following each inspection.

Carbon Monoxide - The Silent Killer

Carbon monoxide is an odourless, colourless gas produced by incomplete combustion. A faulty or poorly serviced gas boiler can produce dangerous levels of carbon monoxide without any visible warning signs. Symptoms of carbon monoxide exposure include headaches, dizziness, nausea, and confusion - and prolonged exposure can be fatal.

We strongly recommend fitting a carbon monoxide alarm near your gas boiler and in bedrooms. We also test for carbon monoxide as part of every service and inspection.
