Why Is Your Water Heater Making Noises?
Hearing popping, rumbling, or sizzling sounds from your water heater? You’re not alone. Sediment buildup often causes these noises inside the tank, a common issue in areas with mineral-rich water. Over time, minerals like calcium and magnesium settle at the bottom of the tank, forming a layer of sediment.
When the heating element or burner activates, water trapped beneath the sediment starts to boil, creating the popping or rumbling sounds you hear. This buildup doesn’t just create noise—it also impacts the efficiency of your water heater. The sediment acts as a barrier, making it harder for the heater to warm the water, increasing energy use and potential wear on the unit.
A thorough tank flush can help resolve this issue by removing the sediment buildup. This quiets the noise and allows your water heater to run more efficiently and last longer. Regular maintenance like this can keep your unit running smoothly and reduce the risk of costly repairs down the line.

Signs of Water Heater Issues
Your water heater plays a crucial role in your home, and spotting early warning signs can help avoid larger problems. Here are some of the most common indicators your water heater may need attention.
Fluctuating Water Temperature
If you’re noticing inconsistent water temperatures during use, it might be a sign of sediment buildup in the tank or an issue with the heating element.
Unusual Noises
Popping, rumbling, or banging sounds coming from your water heater can signal sediment accumulation. Over time, this can compromise the unit’s efficiency and potentially lead to damage.
Visible Leaks
Puddles around the water heater’s base or dripping from the tank clearly show that something is wrong. Even minor leaks should be addressed promptly to avoid water damage.
Rusty or Discolored Water
If your hot water appears rusty or has a metallic taste, it could point to corrosion inside the tank. Ignoring this problem increases the risk of tank failure.
If you notice any of these signs, don’t wait until the issue worsens. Contact Allen Service for same-day service and reliable water heater solutions. Se habla español.

Conventional vs. Tankless: Performance at Altitude
When selecting a water heater in Denver, thinking beyond just size is crucial. The city’s high altitude introduces unique challenges due to lower oxygen levels, which can affect the combustion process in natural gas water heaters. These systems often need adjustments, like being “derated,” to function efficiently and safely at Denver’s mile-high elevation. On the other hand, electric water heaters operate without being influenced by altitude.
For those seeking energy-efficient options, tankless water heaters—also called on-demand systems—are popular. However, Denver’s colder incoming groundwater temperatures can put extra strain on these systems. Heating water instantly in such conditions requires more energy, which may impact their performance.
Understanding how different water heaters perform in Denver’s climate is key to choosing the best option. Whether you opt for a traditional tank model or a tankless system, it’s important to pick one that can handle your household’s hot water needs while performing well in high-altitude and colder conditions.
