Although a boiler is among the most intensively used household appliance, it lasts a great deal of time before giving up on you, especially when you ensure regular maintenance.
However, as many homeowners find out the hard way, they eventually throw in the towel and leave you with ice-cold showers in the middle of winter. Luckily, there are tell-tale signs that your boiler needs replacement.


Regular Breakdowns

A well-maintained boiler should last months without showing any issues. If yours needs a repair every other week to keep it running, then you need a new boiler. This is because the money you regularly pay for the repairs or replacement parts may exceed the initial buying cost of a new boiler. If you’re not sure whether or not you should call a professional emergency boiler repair, you can run an analysis of the total cost of repairs and compare that with the buying and installation price of a new boiler.

Water and Carbon Leaks

Leaks are the most serious issues you’ll find with any boiler. A long term water leak may lower the structural integrity of your home and lead to mould growth, which can be especially dangerous to asthmatic people. Besides water leaks, your boiler could have carbon leaks, which is fatal if it goes undetected. Some of the warning signs for carbon leaks include:

• Sooty stains around your appliance; could be dark or brownish-yellow
• Pilot lights blowing out frequently
• Increased condensation in your windows
• Your appliance burns with a yellow flame instead of a crisp blue one

If you notice any of these signs, leave your house immediately and call gas inspectors before getting a repair person to replace your boiler. You may also install a carbon alarm in your home to ensure that you and your family are safe.

Your Boiler Is Ten Years or Older

With regular maintenance, your boiler could last up to 15 years without breaking down completely. However, at some point, you will need to have it replaced. There are two main reasons to have your unit replaced, and they include:

High risk of Complete Breakdown

Even if it’s functioning effectively, it is highly likely that it will fail when you least expect it. Besides, your engineer may find it challenging to find replacement parts for your boiler, which will render your appliance useless eventually.

High Running Cost

Besides, running an old boiler causes high energy bills. A smooth, direct way of checking your boiler’s energy efficiency is looking at the rating on its ERP label. This label comes with a seven-point colour scale that begins with a deep green to red colour. The green colour indicates high efficiency while red shows inefficiency. Modern boilers come with a better energy rating than older models, which means that you ought to have yours replaced. Furthermore, new boilers come with better controls that will make you work easier. They are also generally safer than older units.

It Emits Too Many Noises

Under normal circumstances, a boiler should only make noise when firing up and produce a low, constant hum when running. If it begins to produce clunking, whirring, or banging sounds, it’s a clear sign of serious issues ranging from a broken valve to a faulty pump. It could also indicate normal wear and tear. In most cases, such problems tend to recur even after repairs. As such, you may ask your engineer to advise on the best way forward.

Radiators Take Too Long To Heat Up

If your boiler takes hours to produce hot water or your house is constantly running out of hot water, you may have a faulty radiator. It could also mean that your boiler is filled with sludge that’s causing blockages, or the system is too corroded. You ought to call a professional repair person to let them inspect and repair the system, but if problems persist, have the whole unit replaced.


These are the most common signs that you should look for when you suspect that your boiler needs replacement.
