Why Your Hot Water Keeps Running Out

Nothing disrupts your daily routine like running out of hot water. Whether it happens in the middle of a relaxing shower or when you’re trying to get through a pile of dirty dishes, the lack of hot water is both inconvenient and frustrating. If this issue happens regularly, it could be a sign that something’s wrong with your water heater. The good news? Many common problems have straightforward solutions, especially when caught early. Below are the most common reasons your water heater may be underperforming and what you can do to fix them according to Parson Plumbing and Drains, your local experts for water heater repair in Columbus.

Sediment Buildup in the Tank

If your home has hard water containing a high level of minerals like calcium and magnesium, those minerals can accumulate in the bottom of your water heater tank over time. This sediment buildup creates a barrier between the water and the heating element, making it harder to heat your water efficiently. You may hear popping or rumbling noises, a telltale sign of sediment buildup.

Schedule a professional tank flush at least once a year to remove built-up sediment. This routine maintenance can significantly extend the life of your water heater and restore its full heating capacity.

Thermostat Settings or Thermostat Failure

Water heaters have thermostats that control the temperature of the water inside the tank. If your thermostat is set too low (typically below 120°F) you’ll get lukewarm water at best. On the other hand, if the thermostat is malfunctioning, it may fail to properly regulate temperature, causing fluctuations.

First, check and adjust your thermostat to 120°F–130°F for ideal performance. If your water still isn’t hot enough or the temperature is inconsistent, call Parson Plumbing and Drains to test the thermostat and replace it if necessary.

Faulty Heating Element (for Electric Heaters)

Electric water heaters rely on one or two heating elements to warm the water. These elements can burn out or become corroded over time, especially if sediment buildup is present. If one element fails, your water heater may only produce half the hot water it should.

A licensed plumber can test the heating elements for continuity and replace any that have failed. Replacing heating elements is generally a cost-effective repair that can quickly restore your hot water supply.

Water Heater Too Small for Demand

If your family has grown, you’ve added new appliances, or recently renovated your home to include a soaking tub or additional bathroom, your water heater may not be able to keep up. Constantly running out of hot water could be due to a tank that’s simply too small for your current needs.

Consult the experts at Parson Plumbing and Drains to evaluate your household’s hot water usage. Upgrading to a larger tank or investing in a tankless water heater, which provides hot water on demand, may be the long-term solution you need.

Aging or Outdated Water Heater

Water heaters don’t last forever. Most conventional tank models have a lifespan of 8–12 years. After that, performance often begins to decline due to wear and tear on internal components. If your heater is near or past this age, a drop in hot water availability is expected.

If your water heater is reaching the end of its lifespan, replacement may be more cost-effective than constant repairs. Newer models are more energy-efficient and reliable, which can also lower your utility bills over time.
