Tankless Water Heater Loud Humming

What Causes a Tankless Water Heater to Produce a Loud Humming Noise

If you’ve ever owned a tankless water heater, you may have experienced the annoyance of a loud humming noise. But what exactly causes this sound? Let’s dive into the possible reasons behind it.

Improper Installation

One common culprit for a tankless water heater humming sound is improper installation. If the unit isn’t installed correctly, it may vibrate against the wall or floor, causing the humming noise. Make sure to hire a professional plumber or technician to install your tankless water heater to avoid this issue.

Water Flow

Another factor that can contribute to the humming noise is water flow. If the water flow is too high or too low for the unit, it can create turbulence within the pipes, resulting in the humming sound. Adjusting the flow rate might be necessary to minimize the noise.

Scale Buildup

If you live in an area with hard water, scale buildup could be the reason behind the humming noise. Over time, minerals in the water can accumulate on the heating elements, causing them to vibrate and produce the humming sound. Regular maintenance, such as descaling the unit, can help prevent this issue.

Malfunctioning Components

Sometimes, the loud humming noise is an indication of a malfunctioning component. It could be a faulty fan, motor, or even a loose connection. If you suspect a problem with a specific part, it’s best to contact a professional technician who can diagnose and fix the issue for you.

How to Resolve the Humming Noise

Now that we know some of the possible causes of the loud humming noise in tankless water heaters, let’s explore how to resolve the issue.

Check Installation

If you suspect that improper installation is the root cause, visually inspect the unit to ensure it is securely mounted and not coming into contact with any surfaces. If you notice any issues, consult with a professional to reposition or secure the unit properly.

Adjust Water Flow

To optimize the water flow and reduce the humming noise, consider adjusting the flow rate. Most tankless water heaters have settings that allow you to control the flow. Experiment with different settings until you find the sweet spot that minimizes the noise.

Perform Regular Maintenance

To prevent scale buildup and potential humming noises, make sure to perform regular maintenance on your tankless water heater. This includes descaling the unit periodically and cleaning any filters or screens. Follow the manufacturer’s instructions for maintenance procedures and frequency.

Consult a Professional

If you’ve tried the above steps and the humming noise persists, it’s time to consult a professional. A qualified plumber or technician can accurately diagnose the issue and recommend appropriate repairs or replacements. Don’t hesitate to seek professional help to ensure the optimal functioning of your tankless water heater.

By understanding the potential causes and implementing the suggested solutions, you can enjoy the benefits of a tankless water heater without the annoyance of a loud humming noise. Remember, proper installation, water flow adjustment, regular maintenance, and professional assistance are key to a quiet and efficient tankless water heating experience.

Why is my tankless water heater so noisy

One of the common concerns people have with tankless water heaters is the noise they can produce. If you’ve ever wondered why your tankless water heater seems to be making more noise than necessary, well, you’re not alone! Let’s take a look at some possible reasons why your tankless water heater is so noisy.

1. Combustion Noise

Tankless water heaters rely on combustion to heat the water. This combustion process can create some noise, especially when the heater is operating at full capacity. The sound may resemble a low rumbling or a continuous hum. The good news is that most tankless water heaters are designed with noise reduction features, so the sound should not be overly disruptive.

2. Buildup of Sediment

Over time, sediment and minerals can accumulate within the tankless water heater. This buildup can cause rattling or banging noises during operation. Regular maintenance, such as flushing out the system, can help prevent sediment buildup and minimize the noise. So, if your tankless water heater is starting to sound like a percussion instrument, it might be time for a little maintenance.

3. Water Flow Noise

When hot water starts flowing through the pipes, it can create a whooshing or whistling sound. This is more noticeable in tankless water heaters because they heat the water on demand, causing sudden changes in water flow. If the noise is bothering you, you can try adjusting the water pressure or installing noise-reducing devices, such as water hammer arrestors.

4. Venting Issues

Improper venting can also contribute to noise problems. If the venting system is not designed or installed correctly, it can cause air to rush through the pipes, resulting in whistling or hissing sounds. If you suspect venting issues, it’s best to consult a professional to ensure proper installation and avoid any potential safety hazards.

5. Expansion and Contraction

As the tankless water heater heats up and cools down, the metal components can expand and contract, causing creaking or popping noises. This is typically normal and harmless. However, if the noises are excessively loud or accompanied by other issues like water leaks, it’s best to have a technician inspect the unit to rule out any underlying problems.

Let’s dive into the facts and fiction surrounding this common misconception.

Debunking the Jet Engine Myth

Contrary to popular belief, tankless water heaters do not sound like jet engines ready for takeoff. While it’s true that these units produce some noise during operation, it is far from the deafening roar one associates with a jet engine. In fact, the noise levels are comparable to a gentle hum or a soft whirring sound.

Identifying the Factors of Noise

Several factors contribute to the noise level of a tankless water heater. First and foremost, the brand and model play a significant role. Higher-end models are specifically designed to reduce noise levels, often incorporating insulation and sound dampening technologies. On the other hand, cheaper models may produce louder noises due to their less advanced construction.

Isolating the Sources of Sound

To understand the noise produced by tankless water heaters, it’s essential to identify the sources. One source of sound is the burner, which creates a combustion noise similar to a gas stove. The sound of water moving through the pipes can also be heard, especially if the pipes are poorly insulated or if water flow is high. Lastly, the fan, which helps in venting fumes, can contribute to the overall noise of the unit, but its operation is far from resembling a jet engine.

Strategies for Noise Reduction

If you find the noise level of your tankless water heater bothersome, there are a few measures you can take to reduce it further. Insulating the pipes can help minimize the sound of water flowing, while adding insulation around the unit itself can reduce the overall noise level. Additionally, positioning the water heater away from living spaces or bedrooms can help mitigate any sound disturbances.

While it’s true that tankless water heaters produce some noise during operation, it’s far from resembling a jet engine. The noise level is typically on par with a gentle hum or soft whirring sound, rather than a deafening roar. By understanding the factors that contribute to noise and implementing simple strategies for noise reduction, you can enjoy the benefits of a tankless water heater without any unfounded fears of living next to an airport runway.

Water Heater Makes Noise When Hot Water is Turned On
