Why Is My Water Heater Making Noise?

Published by Derek Cormier

If your water heater is making popping, gurgling, or banging noises, it could be more than just a minor annoyance, it’s often a sign that something’s wrong. At Climate Experts Air, Plumbing & Electric, we frequently address these unsettling sounds with professional water heater maintenance and repair. 

Keep reading to learn more about the common causes behind these noises and how you can prevent further issues, ensuring your water heater stays efficient and quiet in your Melbourne FL home.

Sounds Escape Through Sediment Buildup

As minerals like calcium and limescale settle at the bottom of your water heater, they create a barrier that traps air bubbles when the water heats up. This trapped air is what causes the popping and banging sounds you hear.

The solution? A professional flush of your water heater to clear out the sediment. This process removes the buildup and helps your system run more efficiently.

If you’re looking for a maintenance-free option, a tankless water heater might be the way to go. Without a storage tank, you won’t have to worry about sediment or the need for regular flushing.

Thermal Expansion Produces Natural Cracking Sounds

Even the most energy-efficient water heating systems can make noises during operation. The metal tank and connected pipes will naturally expand and contract as they heat up and cool down, often resulting in a slight ticking or cracking sound. 

An Aging System May Be Crying for Help

You might be due for hot water system upgrades if your unit is nearly a decade old and keeps making noise. Couple this with higher energy bills, and it’s a telltale sign that a replacement is in order.

Modern gas and electric water heaters with high efficiency ratings help save money. They also tend to heat water without making a peep, so you don’t have to listen to disruptive noises throughout the day. If you’re looking to make an eco-friendly upgrade, ask an expert about a hybrid water heater setup. 

Incorrect Water Pressure Creates Unpleasant Sounds

Every component in your plumbing system needs adequate water pressure to work properly, including your water heater. High water pressure can lead to high-pitched squealing or whistling sounds inside the tank. As pipes send pressurized water through the tank, the force often results in unwanted noises that grab your attention. 

Be mindful of any whistling noises you hear from your unit. As the problem persists, you risk further wear and tear on your system. Contact our expert team to inspect the equipment and adjust your water pressure. If necessary, they may need to install a special valve to reduce the pressure.
