Vital Clues That Indicate It’s Time for a New Boiler

The central heating boiler in your home has a shelf life. They are not built to last forever, though some people might get lucky and find one that can run for two decades without a breakdown. They require an annual service and spare parts when there is a fault. People put off a boiler replacement for as long as possible because they are expensive. The labour charges are significant too; gas engineers and plumbers aren’t cheap. It is a job that must be carried out by professionals because of the dangers involved. Indeed, it is illegal in the United Kingdom to interfere with a gas installation unless you are qualified and listed on the Gas Safe Register.

If your boiler is ten years old or more, you should start looking for the warning signs that all is not well and it is due for a replacement. Here are a few vital clues that indicate it’s time for a new one.

Carbon Monoxide Readings

The staff at PlumbArena told me that if your carbon monoxide alarm indicates levels are high, you should switch off all of your gas appliances. Then open the windows, and call for expert help immediately. Carbon monoxide is a silent killer, and you must not ignore it. It could be due to a blocked gas flue or a problem with the combustion. When a problem such as this presents, it is best to replace the unit. Repairs on an antique boiler are pointless.


If the appliance is in the airing cupboard, have you noticed any dirty wet marks on any of your clothes. The heat exchanger could have a crack in it that only leaks when it is heated by the burner. That is because the metal expands when it is hot. A new heat exchanger may cost almost as much as a new boiler, so it is not sensible to waste money on it.

Running Costs

As a boiler gets old and loses its efficiency, it will cost more to run. Have you noticed that your bills are creeping up? Of course, you must take into account all of the recent price hikes by the energy suppliers.


If your unit breaks down every year, it probably costs a fortune to repair it. It is an indication that all is not well with it, so replace it before it suffers a catastrophic failure.


When the engineer comes out to repair or service your system, do they have problems sourcing spares? We mentioned the shelf life of your boiler earlier, and spares will run out towards the end of it.

The good news is that you might be able to get a new boiler under The Green Deal; a scheme run by government to help you afford to make improvements to the efficiency of your home. The new boiler might also add value to your house if you were thinking about selling up and moving. At least, you will be confident that the new appliance will not let you down when the weather is at its worst, and you can sleep safely in your bed. That has to be worth every penny it costs to replace it.

Boilers are sent to try us, so don’t let it get you down. The experts can fit a new one in just one day. That’s not so bad.
