Top 5 Signs Your Gas Heater Needs Maintenance

As we are in the colder months, it’s important to make sure your gas heater is in good working condition. Not only does regular maintenance ensure that your heater will keep you warm all winter long, but it can also prevent potential safety hazards from occurring.

Depending on the type of gas heating also determines the frequency in which you should get maintenance check-ups. For example, gas furnaces should be maintained annually while gas fireplaces only need to be serviced every other year. But how do you know when your gas heater needs maintenance from a gas plumber?

Here are the top 5 signs to look out for:

1. Unpleasant Odours:

If you notice a strange smell coming from your heater, it could indicate that something is not quite right. A musty or rotten egg smell could mean there is a gas leak, while a burning odour may suggest an issue with the ventilation system. The reason for the unpleasant odour should be inspected by a professional because it's likely a gas leak.

If you start to notice a strange smell coming from your gas heater, it’s definitely time for maintenance. The odour is an additive so that people can smell the gas, without it, we wouldn't be able to smell it and therefore, we wouldn't know there was a leak.

​

2. Yellow or Flickering Flames: 

A properly functioning gas heater should have a steady blue flame. If you notice any changes in colour or flickering flames, it could be a sign of an issue with the burner or ventilation system.

Why does my gas heater have a flickering flame?

A flickering flame may indicate that there is a blockage in the burner or ventilation system, causing an uneven flow of gas. This can be dangerous as it increases the risk of carbon monoxide poisoning. A gas plumbing company that specialises in gas heating systems is what you need as you should have this inspected. Might be just a simple job to clean the burner to ensure a steady and safe flame.



3. Strange Noises:

Your gas heater should not be making loud or unusual noises. If you hear rattling, banging, or other strange sounds coming from your heater, it could mean that there is a loose component or debris build-up inside the unit.

Why is my gas heater making noises?

Strange noises could mean that there is an issue with the fan, motor, or burner in your gas heater. These components may need to be cleaned or replaced during a maintenance check to ensure your heater is functioning properly and safely.

4. Poor Performance:

One of the most obvious signs that your gas heater needs maintenance is a decrease in performance. If your heater is struggling to reach the desired temperature or takes longer than usual to warm up a room, it may be time for a tune-up.

Why isn’t my gas heater heating up properly?

A lack of regular maintenance can cause various issues with your gas heater, such as dirty filters, clogged burners, or malfunctioning parts. These issues can significantly impact its performance and should be addressed by a professional technician during a maintenance visit.



5. Age of the Heater:

Lastly, consider the age of your gas heater. If it is approaching the 10 to 15-year mark, it’s wise to schedule regular maintenance checks even if it seems to be functioning well. An ageing heater may not show immediate signs of wear but can become less efficient over time.

Are older gas heaters less efficient?

Older units may require more frequent repairs and maintenance, and their efficiency can significantly decline. Investing in a professional inspection can help determine whether repairs are necessary or if it may be time for a replacement.
