Why does my hot water heater sound like it’s running?

When the hot water in the tank heats and expands, it pushes through the sediment to the top of the tank, which causes the sediment to shift against the sides and bottom of the water tank, resulting in a rumbling sound.

Is it normal to hear water heater noise?

Banging/Rumbling: Banging and rumbling are among the most common water heater sounds. Typically, these noises can be attributed to excess sediment build-up. When enough sediment accumulates in your water heater tank, it may react with the heating element to create those little mini-explosions you are hearing.

Why does my hot water tank sound like it’s boiling?

Then, because the bottom of the tank is where your burner is, when the water starts heating up and bubbling, it’s fighting to get above the calcium and lime sediments. This causes bubbling and boiling noises (sounds like a coffee maker) or perhaps more of a rumbling noise.

Why does my water heater sound like its gurgling?

Rust, sediment, and mineral buildup in the tank are typically the cause of hot water heater gurgling noises. This is common in older water heaters, as they are more prone to rust and buildup. When you turn the shower or faucet on, the hot water in the water heater tank rises to the top for dispersal into your house.

Can a water heater explode?

Anything that causes excess pressure on your water heating system, such as a poor anode rod, or a lot of sediment buildup, can all cause your water heater to explode. A gas leak can also cause your water heater to explode because it is a tremendous fire risk.
