A Plumbing Company Explains Why Your Water Heater Is Taking Too Long To Heat Up | Oak Ridge, TN

Most households in the United States suffer from a hot water crisis. Nothing is frustrating if your hot water doesn’t last long to finish your morning shower. But it’s common for your water heater to act up at times. Sometimes, it’s because the water has to pass through a lot of piping to get heated; in some circumstances, you could have plumbing issues.

Water heaters have many parts; thus, different issues can keep them from working correctly. If you have to wait for some time to get hot water flowing down your showerhead, keep reading to know what’s interfering with the smooth working of your water heater.

Water Heater Setting Is Too Low

One way to determine why your water heater is taking too long to heat up is by checking if it’s dry. If your hot water faucet doesn’t produce any steam, you can change the temperature setting on your thermostat or electric water heater to the required setting. Adjusting the settings does not need you to contact a plumbing company.

However, you should not set temperatures above 120 degrees as this could expose you to scalding and third-degree burning.

Tank Size

Usually, large water heater tanks take a long time to heat up. Most residential water heater tanks can hold between 20 and 100 gallons. For instance, if your water heater is large, the burner will take more time to heat the tank.

If you have a large family, you should consider installing a tankless water heater to avoid wasting time waiting for water to heat. A local plumbing company in Oak Ridge, TN can help you mount a heater in your home to have an endless hot water supply.

Sediment and Scales Build-Up

Sediment is a build-up of mineral deposits such as Magnesium and Calcium inside your water heater. Large amounts of sediments in your water heater can cause scales to form on the inside walls, blocking hot water from rising and slowing the process of heating your tank.

Scale build-up prevents hot water from passing through your heater and reduces the heater’s efficiency. A popping sound from the water heater indicates the presence of sediment in the tank.

While bathing or washing utensils, you may experience an unexpected loss of hot water, followed by a sudden flow of scalding hot water because your tank cannot regulate the water temperature. To fix this issue, contact a plumbing company near you to correct the problem.

Fuel Type

A storage tank water heater can be fueled by electricity, natural gas, propane, heat pump, oil, or solar.

Homeowners looking for fast water heater options should choose gas water heaters over electric ones. Gas water heaters tend to be twice as fast as electric ones. Although natural gas water heaters cost more than electric ones, they tend to be more efficient to operate.

If you are tired of waiting a long time for water to heat and live in an area where gas is available, you can reach out to a plumbing company in Oak Ridge, TN to install a gas water heater.

Temperature Rise

The temperatures in your area can affect the speed at which your heater warms the water. Sometimes your water heater may be in good working condition, but it takes long periods to heat your water due to the temperature in your place.

You can’t do anything to change the temperatures in your place, but your local plumbing company can insulate your pipes. If you are experiencing long waits for the water to heat in your home regardless of the season, you should contact a plumbing technician to inspect your heater.

Old Water Heater

Just like any other device, the water heater gets old. If your water is over ten years old, essential parts can fail. For instance, the heating element, thermostat, and thermal switch can malfunction.

Your water heater may not be producing enough supply of hot water because it’s old and approaching the end of its lifespan. A plumbing company in Oak Ridge, TN can help you determine the problem and decide if the water heater needs to be replaced or repaired.


Another reason your hot water may take longer to preheat is the distance between the water heater and your faucet or shower. The larger the distance between your hot water tank and your shower or tap, the more it will take for the hot water to get there.

If the pro from the plumbing company installed your water heater in one corner of the house and your shower is in the other, this could be a significant reason your water is taking too long to heat.

First-hour Rating

These are the gallons of hot water your water heater can heat per hour. In most homes, the larger water volumes are primarily used in the morning when people are taking showers. This number can be used to determine the best first-hour rating.

So, for instance, if you and your family use 40 gallons of hot water in the morning, the best match for a water heater for you would be one with a first-hour rating of about 38 to 42 gallons.

Depending on how much hot water you use at one time, if it’s taking too long for your water to reheat, it’s possible that your water heater’s first-hour rating is too low.

In such a case, you should consult a plumbing company to assist you find a water heater that meets all your needs.
