Oil Boiler Service

Your oil boiler works hard to keep your home warm and your water hot — especially through the winters. To keep it running safely and efficiently, it needs regular care and attention. At MyH2O, we provide professional oil boiler servicing, maintenance, and replacements for homeowners across Ireland.

With years of experience in heating systems, our qualified technicians ensure your boiler is performing at its best — helping you reduce fuel costs, prevent breakdowns, and extend the lifespan of your equipment.

Whether your system needs an annual tune-up, a deep clean, or a full replacement, you can rely on us for honest advice, expert workmanship, and exceptional service.

Annual Boiler Servicing

If your heating system feels less powerful or your oil usage has increased, it could be a sign that your boiler needs maintenance. An annual boiler service keeps your system running efficiently and safely throughout the year. During a service, our engineer will:

Inspect and clean the combustion chamber and burner
Replace the oil nozzle and filter
Check seals, flue, and safety devices
Test and calibrate the system for maximum efficiency
Provide a detailed service report with recommendations

A well-maintained boiler burns fuel more cleanly, uses less oil, and produces fewer emissions — saving you money while keeping your home comfortable.

If your boiler is more than 10–15 years old, a new high-efficiency model can make a dramatic difference to your energy costs and comfort.

We supply and install A-rated condensing oil boilers from trusted brands such as Grant, Firebird, and Warmflow — offering superior performance and reduced fuel consumption.

Upgrading your boiler not only improves reliability but also helps lower your household’s carbon footprint.

Frequently Asked Questions

How often should I service my oil boiler?

Your oil boiler should be serviced once a year, ideally before winter. Regular servicing helps ensure efficiency, prevents costly breakdowns, and keeps your system operating safely. Annual servicing is also required to maintain most manufacturer warranties.

What happens during an oil boiler service?

During a service, our technician will inspect, clean, and test all major components. This includes the burner, combustion chamber, filters, oil nozzle, and flue. We’ll replace worn parts where needed, adjust the system for maximum efficiency, and provide a full performance report afterward.

How do I know if my oil boiler needs maintenance?

Common warning signs include:

Boiler takes longer to heat water or radiators
Unusual noises like banging or rumbling
Black smoke or sooty marks around the flue
Sudden increase in oil usage
Frequent resets or ignition problems
If you notice any of these, book a service as soon as possible to prevent further issues.

What’s the average lifespan of an oil boiler?

Most oil boilers last 10 to 15 years, depending on brand and maintenance. Regular servicing can extend this lifespan significantly by preventing damage and ensuring all components work efficiently.

Is it worth replacing an older but working oil boiler?

Yes — if your boiler is more than 10 years old, a new condensing model can improve efficiency by up to 30%, cutting your annual heating costs and reducing carbon emissions. Modern boilers also heat faster, run quieter, and offer better reliability.

How much does an oil boiler service cost?

Prices vary by location and system type, but a standard service is generally affordable — and much cheaper than an unexpected breakdown. We provide clear, fixed quotes before any work begins.

What brands of oil boilers do you service or install?

We service and replace all major oil boiler brands, including Grant, Firebird, Warmflow, Pallas, Riello, and Worcester Bosch. Our engineers use only genuine replacement parts to maintain performance and warranty coverage.

How long does it take to service an oil boiler?

A typical service takes about one hour, depending on your system’s condition. We’ll schedule a convenient appointment and ensure everything is left clean and tidy once the job is complete.

Can you replace my old oil boiler with a more efficient model?

Absolutely. We’ll assess your existing setup and recommend the most suitable A-rated condensing boiler for your home’s size and heating demand. Installation usually takes one day, and we’ll handle everything from removal to testing.

How can I keep my oil boiler running efficiently between services?

You can help by checking your oil tank regularly, keeping the area around your boiler clear, and bleeding your radiators occasionally to improve circulation. Most importantly, never skip your annual service — it’s the best way to maintain long-term performance.
