Sediment buildup in your water heater can significantly impact its efficiency and lifespan. If left unaddressed, this buildup, often caused by minerals in your water supply, can lead to clogs, leaks, and increased energy consumption. The article will explore why sediment buildup happens, the issues it may cause, and what you can do about it.
Why Sediment Buildup Happens in Water Heaters
Sediment buildup in water heaters occurs primarily due to the minerals naturally present in your water supply. When water is heated, minerals such as calcium and magnesium dissolve and settle at the tank’s bottom. Over time, this accumulation forms a layer of sediment, which can harden if left unchecked, potentially causing issues with your water heater’s efficiency and longevity.
In regions with very hard water, this buildup happens more quickly. While these minerals benefit bone health, they are not ideal for your water heater. The harder the water, the faster sediment accumulates, making it particularly important to monitor your water heater if you live in a hard water area.
Effects of Sediment on Your Water Heater
The layer of sediment acts as an insulating barrier between the heating element and the water, which means the heating element has to work harder to heat the water. This can lead to longer wait times for hot water and higher energy bills, as your heater uses more energy to do its job.
Another issue caused by sediment buildup is the noise it can create. As the minerals settle and harden, they can form chunks of sediment that will shift around and cause popping or rumbling sounds. This noise occurs because the heating element is trying to heat the water beneath the sediment layer, causing bubbles of steam to form underneath the sediment. These trapped steam bubbles create the sounds many people hear when their water heater is under stress.
Sediment can also shorten the lifespan of your water heater. Over time, the buildup can cause the tank to overheat, leading to premature failure of internal components like the heating element or the thermostat. Additionally, the sediment can cause corrosion inside the tank, which may lead to leaks and more serious damage.
How To Address Sediment Buildup
If you’ve noticed a decrease in your water heater’s efficiency or have heard unusual noises coming from your tank, sediment buildup could already be causing issues. It’s essential to address the problem promptly to prevent further damage.
The best course of action is to have a professional plumber inspect your water heater. They can clean the tank thoroughly to remove the sediment and check for any damage caused by the buildup.
In more severe cases, the buildup may be so extensive that the heating element or even the entire water heater needs replacement. If this happens, it’s a good opportunity to upgrade to a higher-efficiency model designed to handle sediment buildup more effectively. Some newer water heater models come with built-in features that reduce sediment formation or slow its accumulation, making them a worthwhile investment for long-term savings.
Regular Maintenance Helps
Regular professional maintenance is the best way to prevent water heater issues caused by sediment buildup. Maintaining your water heater is far more cost-effective than repairing or replacing it after significant damage has occurred. We recommend having your water heater serviced at least once a year.
Our plumber will flush the tank during a maintenance visit to remove sediment. They will also replace the anode rod if necessary to prevent corrosion and check for leaks or any signs of wear and tear. They will also verify that the thermostat is calibrated correctly and set to a safe level, typically around 120°F, to prevent overheating. Additionally, they will inspect the burner assembly (for gas heaters) or heating elements (for electric heaters) to ensure they are functioning correctly and not contributing to efficiency losses. Regular professional attention helps ensure your water heater runs smoothly, efficiently, and safely for years to come.
