5 Common Water Heater Noises
A water heater can make a variety of strange noises, but some are more common than others. Here are five of the most common water heater noises and what they mean:
When a water heater makes this sound, it usually means that sediment has built up, causing the metal to vibrate. This can be dangerous, as it can eventually lead to a heater failure.
When enough sediment accumulates, the water heater’s burner can no longer generate a hot flame to ignite the gas. This will cause your water heater to turn off, and you’ll likely hear a banging noise as it does.
2. Popping Sounds
If your water heater is making popping noises, it’s likely due to the expansion and contraction of metal parts as they heat and cool. This is normal behavior for a water heater and usually doesn’t indicate any problems.
However, if you’re hearing this sound more frequently than usual or if other strange noises accompany it, then it may be indicative of a bigger issue, and you should call a professional immediately.
If you’ve ever heard a hissing sound coming from your water heater, it’s probably because there are air bubbles in the tank. When these air bubbles burst, they make a crackling or fizzing noise that can be quite loud.
The good news is that this isn’t usually something to worry about—it just means there are air bubbles in the tank. These sounds can be caused by high levels of minerals such as calcium carbonate or magnesium sulfate that have been dissolved into your water supply.
If you find yourself hearing crackling noises often when using a hot tap, it’s likely due to scale buildup inside the pipes, which causes them to expand and contract as they heat up then cool down again.
It’s pretty alarming to hear a ticking sound coming from your water heater, as it usually means that there is a problem with the heating elements. This noise can be caused by a variety of issues, such as loose connections or faulty thermostats.
If you’re hearing this sound, it’s important to call a professional right away. Failing to address the issue could result in a fire hazard due to overheated wires or other components that are causing this noise.
A gas water heater screeching or whistling sound coming from your hot water heater can be caused by a number of things.
If you’re hearing a high-pitched screeching or whistling noise, it’s likely because there is something wrong with the fan that circulates the hot water. This could be due to a number of issues such as:
If the belt that drives the fan is broken, it will cause a screeching noise.
Loose or dirty blades
If the blades on the fan are loose or dirty, they can cause a whistling noise as they spin around.
If the bearings inside of the fan are worn out, it can cause a high-pitched screeching noise.
6. Sizzling Sounds
The hissing or sizzling sound coming from a water heater can be caused by many different things. This could be due to a variety of issues such as:
Cracks within the tank itself
Loose connections at pipes or fittings
Leaks from loose connections will often make their presence known with a sizzling noise.
