How Long Should a Gas Boiler Last?

Posted on 31st August, 2018 | Posted by admin

A new gas boiler should last for up to fifteen years.

Modern gas boilers are a lot more efficient these days, and with new eco-friendly temperature control mechanisms available, which control each radiator on your central heating system as separate entities, you should be reaping the benefits of having an energy efficient heating system in no time.

This ultimately means lower energy bills. Throw an annual gas boiler service into the mix as well, which is essential for your boiler’s health, and there’s no reason why your boiler won’t easily last for the next fifteen years or so without a hitch.

But how do you know when the time is right to replace your boiler?

High Gas Bills

If your boiler is ten years old or more (bear in mind that boilers installed as recently as ten years ago are much less energy efficient than contemporary boilers) and you are experiencing an unexplained increase in your gas costs, then it could be time to have a new boiler installed.

According to Switcher.ie, the average household in Ireland uses 11,000 kW/h of gas per year at an annual cost of €817.69; average in this case applies to a standard three bedroom home, which uses both gas and electricity. There are variables that can put you into the ‘below average use’ category or the ‘above average use’ category (see their useful infographic); Once you have placed yourself in the correct category, if you find that you’re paying much more than other households in your classification, and it’s not down to a universal energy cost rise, then it’s likely time to take a look at your boiler.

Your Boiler is ‘Noisy’

It’s to be expected that older boilers will be noisier than their contemporary counterparts, but if your boiler is extremely noisy to a point where it disturbs you or your household when in use, it could be a sign it’s struggling to cope. However, it could also just be a sign that your boiler needs a bit of TLC, so the first thing to do is to book a gas boiler service. A gas boiler service with a reputable RGII registered company entails a certified gas engineer inspecting and cleaning your boiler and possibly replacing its internal parts. Your gas boiler engineer will know pretty quickly if your boiler does indeed require replacement. If purchasing a new boiler rather than repairing it is more economical for you, any good gas engineer will advise this.

Your Radiators Take Ages to Heat

If your boiler seems to be taking longer each time to heat up your radiators, it could be a sign it’s struggling to cope. Bear in mind, however, that radiators that are warm on the bottom but cold on the top are usually a sign of the system being full with trapped air, so don’t confuse the two; all you would need to do in this instance is bleed the radiators. A radiator that is cold at the bottom but warm on the top is usually a sign of rust and sludge build up, which would require a system powerflush in order to rectify it.

Loss of Pressure

It’s normal for a gas boiler to sometimes lose pressure, but if you find yourself constantly repressurising your boiler, it’s a sure sign it needs repairing at the very least. Your gas boiler engineer will inspect the parts that are responsible for your gas boiler pressure, clean them and test them. If however, the problem is clearly a boiler that has come to the end of its life, your gas engineer will recommend a replacement.
