A new boiler is not something that’s likely to be on your wish list, but although boilers are a necessity and not just a nice-to-have, maintaining them is extremely important. A faulty, or old boiler could not only be costing you extra money on your energy bills, it could potentially be dangerous.

So, how do you tell if you need a new boiler?


  1. Your boiler is older than 15 years. 


The life expectancy of a traditional gas boiler is between 10-15 years. To extend the life of your boiler, you should have it checked over annually. Older boilers are more likely to need repairing and can increase the cost of your energy bills. Because you know that you will need a new boiler within a 15 year period, it’s a good idea to start saving up for a new one before you need it replaced.


  1. Your boiler is needing regular repairs. 


If you’re having to make call outs to a plumber or approved gas safety technician like 1st Call, then it may be worth considering getting a new boiler. When your boiler is being checked out, we’ll be able to advise you on which is the better option – reparation or a new installation.


  1. It leaks water. 


A leaky boiler should be checked out as soon as possible, water can cause damage to your home and a boiler that leaks water could also be at risk of leaking carbon monoxide which can be deadly to your family.


  1. It takes a long time for your house or water to warm up. 


Boilers should work almost instantly, so if you’re having to run the tap for a while before hot water comes through or your house still feels cold even though you’ve had your heating on for a long time, then it’s time to get your boiler looked at. A faulty boiler might cause your water to fluctuate between hot and cold. If you have trouble keeping the water a constant enough temperature to run a hot bath, then this can be a sign that something is wrong.


  1. Your boiler’s flame burns yellow instead of blue. 


A healthy boiler will run with a blue flame, a yellow flame can be a sign of carbon monoxide leakage.


  1. It has a low energy efficiency rating. 


Boilers are given an energy efficiency rating. Modern boilers which have been installed after 2010 are more efficient than older boilers. Boilers are responsible for 55%-60% of our annual heating bills, so if you’re feeling the pinch when your energy bills come round, updating your boiler to a more energy efficient model could save you money in the long term. Inefficient boilers can waste 30% of their energy, whilst modern grade A boilers only waste around 10%. The bigger your house, the bigger impact this wastage has. An inefficient boiler in a tiny mid floor flat won’t cause too much wastage, but if you’re in a terrace or semi detached house, the cost could be significant.


  1. Your boiler is emitting a smell. 


Carbon monoxide is odourless, but if your boiler is omitting a smell it could mean that it isn’t burning properly and is at risk of leaking carbon monoxide.


  1. There are dark marks around the casing of your boiler. 


This is a sign that your boiler could be leaking carbon monoxide.


  1. Your boiler is making banging or whirring noises. 


A noisy boiler is an unhappy boiler, if your boiler has started to make strange noises, it’s a sign that it may need repairing or replacing.
