5 signs your boiler isn’t working efficiently

Mar 10, 2021

As we’re nearing the end of the winter months, the heating will have taken a bit of a battering.  Especially since the majority of us have been at home juggling work and home schooling.


So, you may be aware that at times the house doesn’t feel as warm as it should be or that your heating bills seem to have rocketed.  Are these signs that everything is not as it should be with your boiler?


It’s always best to get any problems sorted out to avoid a complete breakdown of your heating system, especially when you need it most, so here’s our top five things to be aware of.

1. A dramatic increase in gas usage


Yes this could be down to the fact that we’re in our homes more and the heating is being switched on at different times of the day, but it could signal an issue with the boiler itself. If it’s using way more gas than you would expect then get a service booked in to just to eliminate anything.

2. The system is making strange noises


If clunking or whistling noises are coming from your pipes and radiators, then it’s a sign of a limescale or sludge build up.  These noises are common but not normal and as the system gets blocked, it ends up costing more to run.  Over time limescale can cause damage so it’s best to get the system cleansed and flushed through.

3.  There are areas of the house that feel colder


Cold spots are a sign that there are blockages or the boiler isn’t functioning as well as it should.  So if you go into a ‘heated’ room and feel a chill then get the system checked.

4. The pressure keeps dropping


If the pressure keeps dropping to below 1, then you have an issue.  It’s most commonly caused by a leak but if the pressure drops too low, then it can cause damage to the heating system.

5. Your boiler is old


Yes this could be down to the fact that we’re in our homes more and the heating is being switched on at different times of the day, but it could signal an issue with the boiler itself. If it’s using way more gas than you would expect then get a service booked in to just to eliminate anything.


If you’re noticing something different about your boiler that you hadn’t noticed before give your gas engineer a call.  It’s best to get it sorted before it becomes part of a bigger problem.
