Tankless water heaters have become increasingly popular in recent years. They offer many benefits over traditional tank-style water heaters, such as energy efficiency, space-saving, and endless hot water supply. However, one common issue that homeowners face with tankless water heaters is the noise they produce. But how loud is too loud? And why does a tankless water heater produce such noise? In this blog post, we’ll explore the reasons behind tankless water heater noise and provide some tips on how to reduce or eliminate it. So, let’s dive in!
“Why is My Tankless Water Heater So Loud?”
If you’re like most people, you don’t give much thought to your water heater. You turn on the faucet, and hot water magically appears. But if your tankless water heater suddenly starts making noise, you might start to wonder what’s going on. Don’t worry; we’ve got you covered. In this section, we’ll explore some common causes of tankless water heater noise and how to fix them.
The Culprit: Mineral Buildup
One of the most common causes of tankless water heater noise is mineral buildup. Over time, minerals in your water can start to accumulate in the heat exchanger. When this happens, you may hear a popping or banging noise as the water heats up and the minerals expand. To fix this issue, you’ll need to descale your water heater regularly. You can use a commercial descaler or make one yourself with vinegar and water.
The Culprit: Loose Parts
Another possible cause of tankless water heater noise is loose parts. As your water heater heats up and cools down, the metal components can expand and contract. Over time, this can cause screws and bolts to become loose, leading to rattling or clanking noises. To fix this issue, tighten any loose screws or bolts with a wrench.
The Culprit: Water Flow Rate
If your tankless water heater is making a high-pitched whining noise, the issue may be with your water flow rate. If the flow rate is too low, the water can’t move through the heat exchanger fast enough, leading to turbulence and noise. Check your water flow rate and adjust it if necessary.
The Culprit: Gas Pressure
If you have a gas-powered tankless water heater, the noise may be due to low gas pressure. When the gas pressure is too low, the burner may not ignite properly, leading to a popping or hissing noise. Check your gas pressure and adjust it if necessary.
The Culprit: Faulty Fan
Finally, if your tankless water heater is making a whirring or grinding noise, the issue may be with the fan. Over time, the fan blades can become bent or worn, leading to noise and reduced efficiency. If you suspect a faulty fan, call your HVAC technician to replace the part.
While tankless water heaters are generally quiet, noise can indicate an underlying issue that needs to be addressed. By understanding the common causes of tankless water heater noise and how to fix them, you can keep your water heater running efficiently and quietly.
On Demand Water Heater Noise
Tankless water heaters are all the rage, they provide an endless supply of hot water, save precious space in your home, and are energy-efficient. But as with all home appliances, tankless water heaters come with their own set of problems, namely noise.
The Sound of Silence…Not!
One of the main reasons people opt for tankless water heaters is that they are supposed to be quiet. But apparently, the “on-demand” part of the equation means that they are always ready to provide hot water, and in doing so, can sometimes make noise.
Bang, Bang!
Imagine this: You’re taking a relaxing shower, and suddenly you hear a loud banging noise coming from your water heater. Sounds horrifying, right? But fear not, it’s only the sound of water hammer, which is normal and can be solved by simply installing a water hammer arrestor.
High-Pitched Whine
Another sound that can emanate from your tankless water heater is a high-pitched whine. Though it may be annoying, there’s a simple fix for this as well. All you need to do is replace the flow restrictor with a new one.
Rumbling
If you hear rumbling sounds coming from your water heater, it’s usually a sign that there is a buildup of sediment in the tank. This typically happens with older models, but it can still happen with new ones. In this case, the solution is to flush the system and remove any sediment that has accumulated over time.
So there you have it, if your tankless water heater starts making noise, don’t panic. More often than not, the issue is simple to fix and won’t require a professional. Just make sure to perform regular maintenance and keep an ear open for any strange noises. Happy showering!
AO Smith Tankless Water Heater Vibration
Have you ever wondered what’s causing that rattle in your house every time you turn on the hot water? Well, it’s probably your AO Smith tankless water heater. While these units are compact and efficient, they can sometimes be a bit noisy. In this section, we’ll talk about why your tankless water heater is vibrating and what steps you can take to fix the issue.
What Causes AO Smith Tankless Water Heater Vibration
Simply put, vibration occurs when something in the water heater is not balanced or secured properly. This can be caused by a variety of things, including loose screws or fittings, a dirty or clogged filter, or even a faulty fan. Sometimes, the installation may also be to blame, such as if the unit was not properly leveled or if it’s located on an unstable surface.
How to Fix AO Smith Tankless Water Heater Vibration
First things first, turn off the unit and let it cool down before attempting any repairs. Once you’ve done that, take a look inside the unit and check for any loose screws or fittings. Tighten them up as needed.
If that doesn’t do the trick, clean the filter screen to remove any debris that may be causing the vibration. This is a simple process that involves removing the filter and rinsing it under running water. Once it’s clean, reattach it to the unit and turn it back on to see if the noise has stopped.
If you’ve checked the screws and cleaned the filter, but the vibration persists, it may be a problem with the fan. In this case, you’ll need to contact a professional for repair or replacement.
Preventing AO Smith Tankless Water Heater Vibration
The best way to prevent tankless water heater vibration is to ensure that the unit is installed correctly in the first place. Make sure that the unit is level and installed on a solid surface, and that all fittings are tight and secure. You may also want to invest in vibration pads or mounts to help absorb some of the motion and reduce noise.
In conclusion, while AO Smith tankless water heaters are a great way to save space and energy in your home, they can sometimes be a bit noisy. However, with a little troubleshooting and preventative maintenance, you can keep your unit running smoothly and quietly for years to come.
How Loud Should a Tankless Water Heater Be
If you’re concerned about the noise that your tankless water heater is making, you’re not alone. The truth is, tankless water heaters can be noisy, but not all noises are cause for concern. In this section, we aim to answer the question: “How loud should a tankless water heater be?”
Decibels, dB, and Noise Levels
To understand how loud a tankless water heater should be, we first need to know about decibels, dB, and noise levels. Decibels, or dB, is a unit used to measure the intensity of sound. Noise levels are measured in dB, and safe noise levels depend on the location and context.
Normal Tankless Water Heater Noise
Normal tankless water heater noise should be no louder than a soft hum or a refrigerator’s noise. If you can hear a low hum or soft whooshing sound from your tankless water heater, then you have nothing to worry about. In fact, most tankless water heater manufacturers indicate that the normal operating noise level should not exceed 54 dB, which is about the same level as a low conversation.

Why is My Hot Water Heater Making a Horrible Noise
If there’s one sound that can send anyone into a panic, it’s the sound of something going wrong with a major household appliance. And when it comes to your hot water heater, there are few sounds more terrifying than the dreaded “horrible noise.” But what is this noise, exactly? And why is your hot water heater making it?
Sediment Buildup
One of the most common reasons your hot water heater might be making a horrible noise is sediment buildup. Over time, sediment can accumulate at the bottom of your hot water heater tank, creating a layer that can impede the flow of water and cause your heater to work harder than it should. This can create a rumbling or banging sound as water tries to make its way through the sediment.
Loose Heating Element
Another possible culprit of your hot water heater’s awful noise is a loose heating element. If the heating element in your water heater comes loose, it can start to rattle around in the tank, creating a clanging or banging sound that can be difficult to ignore.
Old Age
If your hot water heater is getting on in years, it’s possible that it’s simply reached the end of its lifecycle. As hot water heaters age, the metal in the tank can start to warp and corrode, creating a host of issues that can lead to loud and unpleasant noises.
Solution: Call a Professional
Unfortunately, there’s no quick and easy fix for a hot water heater that’s making a terrible noise. If you’re experiencing this issue, the best thing you can do is call in a professional plumber or HVAC technician to diagnose the problem and provide a solution that makes sense for your specific situation.
In the meantime, try not to panic: many hot water heater issues can be fixed with relatively little fuss or expense, and with the help of a qualified professional, you’ll be back to enjoying hot showers in no time.
Is It Normal for Tankless Water Heater to Make Noise
If you’ve just installed a new tankless water heater, you might be surprised by the level of noise it makes when it’s running. But don’t worry, your water heater isn’t possessed by some kind of demon. It’s perfectly normal for tankless water heaters to make some noise, especially when they’re operating at full capacity.
What Causes the Noise
There are several reasons why a tankless water heater might make noise. One common cause of noise is the flow switch, which turns on and off to regulate the flow of water through the heater. When the switch opens and closes, it can create a clicking or tapping sound.
Another cause of noise is the fan that helps to vent the exhaust gases out of the unit. If the fan is dirty or damaged, it can create a rattling or humming noise.
Finally, tankless water heaters can sometimes make noise simply because they’re working harder than usual to heat the water. If you’re running multiple hot water taps or appliances at the same time, your water heater may be operating at full capacity, which can create a rumbling or humming sound.
How Loud is Too Loud
While it’s normal for a tankless water heater to make some noise, there are a few signs that the noise might be excessive. If the noise is loud enough to disrupt your day-to-day activities or keep you up at night, it’s time to take action.
Try to pinpoint where the noise is coming from, and see if there’s anything you can do to reduce it. In some cases, simply cleaning or replacing a dirty fan or flow switch can help to reduce the noise level significantly.
In conclusion, it’s perfectly normal for tankless water heaters to make some noise. But if the noise is excessive or disruptive, it’s important to take action to address the issue. By understanding what causes the noise and taking steps to reduce it, you can enjoy all the benefits of a tankless water heater without any of the unwanted sound effects.
