5 signs you need a new boiler

Worried your boiler is past its best? Like most things, boilers do have a lifespan. And if you don’t pay attention to the subtle signs, they can break down – often at the most inconvenient times.

So how do you know when it’s time to take the plunge and get a new boiler? Let’s take a look at 5 tell-tale signs your boiler might need replacing…

1. Your boiler has frequent breakdowns

When a boiler has a habit of switching off or giving up on the regular, it’s usually a cry for help. Either you need to replace faulty parts or it’s time for a boiler upgrade.

To get to the bottom of it, you should call a Gas Safe engineer to inspect the boiler. 

We know, a new boiler isn’t cheap. But a faulty boiler can be just as expensive in the long run, and even more inconvenient. To make sure your boiler is ticking smoothly, a yearly service is the minimum – but if you’re forking out on the regular for visits from a Gas Safe engineer, then it’s probably time to replace your boiler.

2. Your radiators take longer to heat up

Do your radiators stay lukewarm or take hours to get hot? Unequal heat distribution in your boiler could prevent your radiators from heating up. Most modern boilers can reach their maximum temperature quickly, so a lethargic radiator could mean your boiler is on the way out.

There could be other causes for your radiator taking longer to heat up – you might need to bleed the radiator or ​clear your central heating system of sludge. 

By contacting a Gas Safe engineer, you can get to the root of the cause.

3. You can hear strange noises coming from your boiler

It’s typical for your boiler and heating systems to make noises, usually a constant hum, which can be a handy reminder that you forgot to turn it off!

But banging, clunking and whirring are sounds you shouldn’t be hearing. And these strange noises could mean that your boiler is on its last legs.

Before rushing ahead with a boiler replacement, ask a heating engineer to take a look at your full heating system. Boiler noises can also be a sign of a sludge build-up in your pipes, which can be quickly fixed by power flushing the system. 

You’ll need a heating engineer to help get to the bottom of the noises and fix the issue.

4. Your boiler has a yellow flame

When a boiler is burning, it should burn bright blue. If it’s changed to a yellow or orange colour, you need an immediate service from a Gas Safe engineer. 

A yellow flame might be a sign that the boiler is leaking carbon monoxide – a colourless and odourless gas that can prove to be fatal.

By calling a gas safe engineer, they can check for carbon monoxide inspection. If the leak is irreparable, a replacement boiler will be recommended.

5. Your boiler is leaking water

Are you finding puddles of water around your boiler? One of the most noticeable signs of a faulty boiler is excessive leakage. Some leaking over time can happen, but if you’ve noticed it’s happening more frequently and at greater volumes, it might be time for a new boiler system.

You should take immediate action, because a leak can lead to further problems like rust and corrosion, as well as structural damage to your home. The boiler will also be more inefficient, which can become costly. To avoid increased costs for your heating and water, and prevent damage to your home, call a heating engineer.
