4 Sounds Your Boiler Shouldn’t Make

If you have a boiler, you know that it is not completely silent as it operates to keep your home warm. However, there are completely normal sounds and then there are sounds that should make alarm bells go off in your head.

Some unusual sounds are a sign that it is time to schedule boiler maintenance in Evergreen, AB. You can keep reading to learn more about the four most common sounds we get calls about that can indicate something is wrong with your boiler. By paying attention to unusual sounds early, you can avoid much worse boiler problems including a boiler breakdown.

1. Gurgling 

Your boiler has to be completely airtight for the system to work as it needs to. But it is not uncommon for air to get trapped in your boiler despite the fact that it is a water appliance. Some air is still needed for proper functioning. But when air levels are too high the trapped air can make a gurgling sound. You can call our team and we can help get this extra air out of the boiler to prevent the sound and also help the unit to work more efficiently without any additional problems.

2. Drone Sounds

A drone sound coming from your boiler could mean that you have a faulty pump. As part of boiler operations, there are pumps that help to move water throughout the system. If one of these pumps stops working, it can impact the entire rest of the boiler.

Other pumps are having to pick up the slack and even that may not be enough to maintain the heat that your home needs. The faulty pump will end up making a drone sound as water pushes through. That’s your sign of problems that need addressing.

3. Whooshing

Blockages within your boiler can prevent water from flowing freely where it needs to go. As a result, water ends up whooshing around these blockages where there are openings available for movement. If you hear a whooshing sound, you may think that it’s not a big deal and that your boiler is in fact working great since you’ve been hearing the water flow.

But in fact, this particular sound is a red flag. If the blockage continues, it could lead to other problems like too much pressure in one area of the boiler and the lack of heat overall. The blockage could even continue developing until it’s big enough to block water flow completely instead of just partially.

4. Kettling

And speaking of pressure, when there is too much pressure buildup inside of your boiler for any reason, you may hear a kettling sound. While it doesn’t happen very often, it is possible for a boiler to explode from having too much pressure inside. There are pressure relief valves on your boiler that you can turn to alleviate pressure from building up inside the system. 

However, if the problem persists you really need to schedule service for your boiler. Having the problem continue means that there is a contributing factor that is not being addressed. You can continue releasing the pressure and it will continue building up. It’s better to get down to the source of the problem and prevent pressure from every building up in your boiler in the first place.
