Tankless Water Heater Repair

Tankless water heaters are a popular alternative to traditional tank hot water heaters. Although they’ve been used in homes since the 1990s, they have steadily grown in popularity in recent years because of their efficiency and convenience.

Although tankless water heaters are more long-lasting and durable than tank water heaters, like all plumbing equipment, they can break down occasionally. If your tankless water heater develops issues, contact the licensed plumbers at Mission Mechanical for accurate, timely, and cost-effective repair service in the Indianapolis, IN area.

How Does a Tankless Water Heater Work?

A tankless water heater operates quite a bit differently than a conventional water heater. As you know, traditional water heaters come with a large tank for holding water. The unit must continuously heat the water throughout the day to ensure it’s ready when you turn on the hot water tap.

Tankless models are also referred to as on-demand water heaters because they heat water as it flows through the unit, providing hot water instantly and continuously. When you turn on the hot water in your home, water enters the system and is immediately heated by an electric element or gas burner. As soon as the hot water is turned off, the system shuts down and stops using energy. Because tankless hot water heaters do not store hot water, they are more energy efficient and have a longer lifespan, typically between 15-20 years. And unlike tank models, they almost never run out of hot water!

Signs Your Tankless Water Heater Needs Repair

A few of the most common reasons your tankless water heater might need repair service include:

Broken Heating Element

Tankless units are powered by electricity or natural gas. On electric units, it’s not uncommon for the heating element to develop problems and fail, causing your water heater to stop working. A plumber will inspect the circuit breaker and wiring to ensure they’re not causing the issue. If the issue is isolated to the heating element, a licensed plumber will replace it with a new one to restore hot water to your Indianapolis, IN home.

Gas Burner Issues

Gas-powered water heaters can experience issues with their burners. Over time, the gas burners’ thermocouples can wear down or the burners themselves can become dirty, leading to issues. Contact a plumber to inspect the unit and make the appropriate repair.

Sediment Buildup

Just like tank water heaters, tankless models can stop functioning properly due to a buildup of scale and sediment, especially if you have hard water. Sediment can develop on parts including the heating element, causing the system to malfunction or break down.

No Hot Water

If the unit cannot produce hot water, there’s obviously an issue. A lack of hot water is commonly due to a problem with the fuel source. Check for blown fuses in the breaker box, and ensure the heater is on and not out of gas. Additionally, a clogged filter, faulty heating element, or malfunctioning thermostat can also cause this issue.

System Overload

Your tankless water heater may become overloaded if too many hot water applications are running simultaneously, such as multiple hot showers. This can result in inadequate hot water or even a complete system shutdown. To avoid this, consider limiting simultaneous applications that require hot water or upgrading to a higher-capacity tankless water heater.
