How do you know when your boiler needs replacing?

As summer starts to wind down, darker, colder nights will be here before we know it, and it’ll be essential to have heating that you can rely on. Find out how you can stay on top of your boiler maintenance with some key boiler replacement signs, so you’re not caught out this winter. 

  1. Boiler age

If you’ve had your boiler for more than 15 years, congratulations on keeping it going without a replacement for so long, however, it’s likely to be far less effective due to its advanced age. Consider taking the plunge and getting a boiler replacement to ensure that you’re best placed to have your heating and hot water running smoothly as the temperature decreases. There are a variety of boiler types you can purchase, so do your research and get the one that’s best for you. 

  1. Dripping or leakage

This is a surefire boiler replacement sign. There may be a damaged pressure valve or pump seal. If the leak is coming from the seal around the pump of your heating system, it may be that it is broken or natural wear and tear has occurred and it needs to be replaced. A trained installer will be able to help you figure out the source of the leaks, but if this is a recurring issue, then it may be time to make an investment in a new boiler.  

  1. Bad smell 

If you notice a strange odour coming from your boiler then treat it as an emergency. A bad-smelling boiler can be a sign of a potential gas leak.  If this is the case, turn off your boiler immediately and contact the Gas Emergency Services. Once you’ve been given the all-clear you might want to think about getting a replacement boiler for peace of mind. 

  1. Blue flame has turned yellow

A healthy boiler should burn brightly with a blue flame. If you notice that your boiler’s flame is yellow, then call an engineer immediately so they can assess the seriousness of the situation. While a bad odour can be a sign of a gas leak, carbon monoxide is odourless, so it’s crucial that you make a habit of checking the colour of your flame. 

  1. Your boiler isn’t ‘A-grade’

Boilers are given efficiency ratings, which as a boiler age will start to decrease. British Gas states that A-rated models operate at more than 90% efficiency, while G-rated boilers run at 70% or less. This lower rating can lead to more expensive energy bills as your boiler is working harder to keep up with its usage. Have a look at your boiler’s rating and you may find that the cost of a new boiler will far outweigh the increasing energy bills in the long-term. 

  1. Radiator taking longer to heat up

Be measured with your assessment here, as a radiator taking a little longer than you’d like to heat up doesn’t mean it’s time for a new boiler. Delayed heating time can be a sign of an internal malfunction that can be fixed by an engineer, however, it may also be a sign your boiler is past its best days and needs replacing soon.  

  1. Hard to find replacement parts

Over time, the production of parts for some older boiler models can sometimes decrease or fall out of circulation. This can make it hard to find replacement parts when a boiler has a fault. While this is not a direct reason to replace your boiler, it is worth bearing in mind. Research the costs of replacing parts and the frequency that you are having to do so. If your boiler regularly breaks it could be economical to upgrade to a newer model.
