When should I replace my boiler?

If you’re frequently experiencing issues with your boiler, constantly requiring a boiler repair, you should consider if a boiler replacement is right for you.

Of course, regularly servicing your boiler should be enough to keep it running efficiently and maximise its life expectancy. Bord Gáis Energy offers a range of Boiler Repair and Boiler Service and Cover plans to keep your boiler in good shape. And with our qualified technicians and 60-day warranty, you get peace of mind that you’ll have a warm home all year long.

But we understand, sometimes, it may be difficult to know when a simple repair or service will do the trick, or when you need to replace or upgrade your system. So, here’s a list of signs that can help you decide if it’s time to put that old boiler to rest.

In general, a boiler has a lifespan of 10-15 years. The older your boiler gets, the more frequent a repair job may be required.

Servicing your boiler once a year should be enough to keep it working smoothly all year, but if you’re facing issues with your heating each couple of months, and the Gas Installer is now a familiar face, maybe it’s time to crunch some numbers, and see if what you’re paying in labour and parts wouldn’t have already bought you a new boiler.

By now, you probably know that boilers have an energy efficiency rating and that you can check your boiler rate. But would you be able to explain how that rating works?

Boilers are rated from A to G: “A” being the most efficient and “G” the least efficient. The efficiency is determined by how much fuel the equipment can convert into energy. G-rated boilers are less than 70% efficient, meaning that 30% of the fuel it consumes is wasted, while A-rated boilers have a 90% efficiency.

Replacing your G-rated boiler with an A-rated one could mean big savings on your annual gas expenses.

It’s a common complaint and usually because sludge and scale have built up in your central heating system over time making them less efficient and less cost-effective to run. Sometimes, a simple Powerflush gets the job done.

But if issues persist even after the procedure, and are not restricted to noises (e.g. you notice that your radiators are hissing, vibrating or banging), this might suggest a more serious problem with the boiler or central heating system, and you could benefit from a boiler replacement or system upgrade.

Efficiency loss is not the only problem when maintaining an old boiler. Replacement parts are not only expensive, but they’re hard to find. Imagine having an urgent issue to fix, only to find that the part you need is impossible to find! Sometimes they’re not even new, but taken off out-of-order boilers, which will leave you with no warranty for that part.

Sometimes it’s not your fault, you gave your boiler all the love and treatment it deserved, but it seems that your boiler’s best days are behind it. A few signs of this might be radiators needing longer times to heat up, or the constant need to re-adjust the boiler’s pressure.

If that seems to be the case, and you’ve made the decision that a new boiler is the right option for you, then there’s no need to worry. We're here to help.
