5 Warning Signs That Your Boiler May Need Repairing

Your central heating boilers will always need repairs or servicing at some point in its life span. Unfortunately, the average homeowner is not that familiar with warning signs telling them that a repair is needed.

Just like any machine, your boiler’s system can become weaker if there are failing or damaged parts. As a result, you might end up dealing with expensive repair costs as usually the rest of the parts within the boiler have also incurred damages.

If you want your boiler to last for a long time and give you a better service, regular maintenance and inspection is necessary. If you ignore the small signs that your boiler isn’t working efficiently and don’t get them checked out, it’s possible the problem might grow into a more serious issue.

To prevent this from happening, here are some telltale signs to watch out for, so you will know if your boiler needs to be repaired sooner rather than later:

1. Boiler Cycles On and Off Constantly

Boiler Cycles On and Off Constantly

A boiler shouldn’t regularly cycle on and off in the first place. If the boiler short cycles, this will run for 3 to 5 minutes and turn off for a few minutes before it starts back up again. When this happens, something isn’t right and needs to be looked at.

This constant cycling on and off can be the result of many problems such as a faulty valve, bad pump, or a faulty thermostat. Make sure you keep your boiler clean with proper regular maintenance. A technician can also troubleshoot the issue and make the necessary boiler repairs accordingly.

2. Strange Noises Coming from the Boiler

Strange Noises Coming from the Boiler

If you notice or hear unusual sounds from your boiler, this can be a symptom of a buildup of limescale and muck on the heat exchanger area of the boiler. The flow of water gets restricted and this results in boiling and overheating that are responsible for those strange noises.

3. Unusual or Unpleasant Smells

Unusual or Unpleasant Smells

Unusual or unpleasant smells around your boiler are also sure indications that something doesn’t work properly in your machine. The smell of oil, plastic or burned metal can be a sign of overheating elements or circuits.

Sulfurous smells or smells similar to that of a rotten egg, most probably mean that there is a gas leak somewhere inside the boiler system. When this happens, you have to shut down the system until an expert arrives to fix the problem.

A boiler might also emit a dust smell or a burning fabric aroma when you activate it for the first time for the season.  This is normal but if this continues for several days, contact a heating engineer right away.

4. Leaking Water

Leaking Water

When you notice puddles or moisture around your boiler, call a technician who can evaluate it as soon as possible. Dripping or stagnant water can bring upon more serious damages to your property in the long run. Leaky central heating boilers can also use more energy with higher risks of bursting.

5. Rising Energy Bills

Rising Energy Bills

If you notice an unexplainable increase in your energy bills, your inefficient boiler might be the culprit. If your unit only works at 70% or lower, this will cost you more monthly expenses. To check if it is possible to lower your bills, technicians can conduct a full service on your boiler to identify the exact problem at hand.

Overall, it’s always recommended to contact a professional to service your boiler regularly and keep it working efficiently within your home, whilst also keeping those pesky repair costs down.
