Gas heater leakages are a common problem in most households, and if not arrested on time, the issue may escalate into a major issue. With this in mind, you are advised to seek professional heater repair services as soon as possible.

Common Causes of gas heater leaks

The following are possible causes of gas heater leakage:

1. Standard-efficiency gas furnaces

There are two commonly used types of gas furnaces: Standard-efficiency gas furnaces, and high-efficiency gas furnaces.

Standard-efficiency furnaces have very few potential causes of leaks, so finding the root of the leak is relatively easy. Notably, the leak may arise from a poorly installed flue – the pipe that channels exhaust out of your house. Moreover, if the vent is too small or poorly installed, the heat is trapped, and over time, it cools to form a liquid.

The water ultimately finds its way into the floor area near the furnace or into the furnace. Whereas this is uncommon, when it happens, it can cause a lot of damage to your furnace. Therefore, if you notice water leaking from your standard-efficiency furnace, call a heater service professional immediately.

2. High-efficiency gas furnaces

Conversely, high-efficiency gas furnaces are much more prone to leaks. This is because high-efficiency heaters utilize dual heat exchange systems to bolster fuel efficiency. However, there exists a gap between the two processes, which allows the air in the furnace to cool very fast (condensation). Usually, the condensation is managed by the drain system, which effectively gets rid of the water. However, the following issues may cause a leak:

  • A blocked drain system
  • Damaged drain pan or drain line
  • One of the heat exchangers not working properly

Whereas these problems are uncommon, they do occur. So if the water is leaking from your high-efficiency furnace, the three issues above are definitely the cause.

Gas heater repair process

If you notice any anomalies with your gas heater, always get a professional gas heater service provider immediately. You should also note that all types of gas heaters need to be serviced at least once every two years. These include space heaters, central heating units, gas log fires, and wall units.

Here is a checklist you can use to determine whether your gas heater needs servicing.

  • If it hadn’t been maintained for the last two years
  • In case you notice water leaks
  • Production of sooty or yellow flames during operation.
  • Pilot light goes off sporadically
  • If you notice any signs of heat damage
  • Any unexplained soot stains on your unit.
  • Walls become extremely hot when the heater is on.

Bottom line: Here is what you need to consider

Having a yearly maintenance appointment can help prevent any of the above-mentioned issues from happening. However, this doesn’t mean you shouldn’t monitor your unit regularly for any leakage.

Therefore, it is always advisable to give QuickAir a call whenever you notice any anomaly with your gas heater before it becomes a major issue. Our licensed technician can assess the heating system and will provide you with a solution. It’s as simple as that! Call now 1300 730 896.
