10 Signs Your Boiler Needs Servicing or Replacing

Oil 4 Wales takes boiler safety and maintenance seriously. We would much prefer you be able to know signs before its too late!

As we come into summer, we become much more complacent about our boilers because… well, we don’t feel like we need them as much to stay warm! But we know first hand, from the amount of call-outs we get in summer, how easy it is for your boiler or boiler to break down – resulting in cold showers and worse!

You don’t want to be caught off guard when you turn on your thermostat and no heat comes on in the winter. Check for these signs that your boiler needs servicing so you can do it now before the weather gets cold and you have to huddle under blankets to stay warm.

Year after year, your boiler works tirelessly to keep you comfortable when the temperatures drop outside.

However, with each passing year, the unit also beings to become more and more worn down, requiring service and eventually complete replacement.

Do you know when your boiler needs servicing? And, did you know investing in regular service may help to extend the unit’s lifespan?

It’s all true – but to reap the benefits of regular service, it’s a good idea to get to know when it is needed.


1. Lack of Maintenance in the Past

You may cringe a bit when you read this one. Can you even remember the last time you serviced your boiler? If not, it’s likely time!

After all, the last thing you want is to wake up one cold night to discover your boiler is no longer working.

If you have put off professional maintenance and service, then now is the time to call for help. This will ensure you have a warm and comfortable winter.

2. Clogged Filters

From time to time, the filter in your boiler may become clogged. When this happens, cleaning or replacing it is a must.

However, as a preventative step, you should also replace the filter at least one time a month.

If you notice your filter is getting dirtier than usual, it may be time to have a professional come to inspect the system to ensure everything is working properly. This will help prevent a very costly breakdown.

3. Leaks

If you ever notice your boiler is leaking, you need to call the professionals (that’s us!).

Leaks aren’t just an indication your boiler isn’t operating efficiently. It may also be a sign that big issues are on their way.

If the boiler is leaking and it goes undetected, it can lead to serious property damage, breed mould and more.

Any sign of a leak could be a serious problem. Don’t wait to call for service.

4. Poor Energy Efficiency

Even if you don’t see any actual signs of a problem, there could be issues. Some homeowners are surprised to discover that an indication of boiler repair may be in their monthly bills.

It’s expected that energy costs are going to rise in all sectors this year. As a result, having a boiler that operates efficiently is beneficial.

While it may be beneficial to have a new boiler installed, the rising costs you are seeing may be a sign of inefficiency.

Don’t spend more than you have to heat your home. Be sure to keep an eye out for indications your boiler may be headed for a breakdown or failure.

5. Slow to Heat Up

There are some homeowners who are hesitant to call the professionals for boiler repair when they can eventually get their home to heat up. However, if the system is taking longer than usual to do this – it could indicate a problem.

Don’t settle for a boiler that’s too slow when it comes to heating your home. This could be a warning sign of a bigger problem.

It’s best to call us at Oil 4 Wales for a service now, instead of waiting for a complete breakdown.

6. Operating Issues

Have you ever experienced a problem where it’s extremely hot in one part of your home and ice cold in another?

If this is the case, then your boiler may not be operating efficiently or properly. What you may attribute to an air handling or control issue may actually be your boiler.

Use this as a chance to have your boiler repaired or replaced.

7. You’ve Begun to Hear Things

Have you begun to hear a hissing sound coming from your boiler? If so, it may be an indication that a deposit has begun to form.

Not all types of boiler issues will require a serious repair or replacement. Professional services can clean your boiler out and provide the regular maintenance needed.

However, if you let the deposits continue to accumulate, then the repairs may be more expensive later on. You may even have to deal with a total breakdown.

8. Age of Your Unit

Do you know how old your boiler is?

If your unit has had provided years of great services from your unit, but it has been more than a decade, then it may be time to invest in a replacement.

Investing in a new unit now can help you save over time because modern units are much more efficient than older ones.

9. Poor Air Circulation

If you ever think that your boiler isn’t heating up to the proper temperature, be sure to pay attention.

The issue could be related to the fan motor or the belt. It’s a good idea to have it checked out by the boiler experts now.

It can be quite expensive to replace the fan motor or the belt.

10. Gas Leakage

If you ever smell gas, you need to turn the boiler off right away.

Also, take steps to avoid sparks from any lighters and switches. You need to have the professionals come out as quickly as possible, as this can be a dangerous situation.
