Tankless water heaters offer enhanced energy efficiency and low operating costs, making them a good choice for people who want to lower their carbon footprints. They also provide an endless supply of hot water for your Lebanon, TN, home. Here are the top tankless water heater problems you may encounter and some tips on what to do if any of these issues occur in your home.

Inconsistent Water Temperature

One water heater problem to be aware of is inconsistent temperatures. If you notice the water is too hot for one shower and not hot enough the next time you shower, check the thermostat on the water heater. If it’s showing the correct temperature, there could be a mechanical fault with the water heater. Avoid setting the water heater to a temperature higher than 120 degrees Fahrenheit. Any hotter could overwork the heater or overheat the water, causing burns.

Mineral Buildup

If your home has hard water, the mineral buildup could affect your tankless water heater. Calcium and magnesium are the most common minerals in hard water. Over time, they cause a scaly buildup that can clog the supply lines to and from your water heater. The buildup hinders the flow of water, creating an insufficient amount of hot water to your fixtures. Flushing the water heater or installing a water softener are ways to solve this issue.

No Hot Water

Tankless water heaters last for at least 20 years, explains the Department of Energy. With no tank, there’s no risk of rust or corrosion. If no hot water comes out of your fixtures, there could be a pilot light problem. Sometimes, it’s as simple as relighting it. However, there could be an issue with the safety or pressure valve, ignition or gas supply. Those problems require professional tankless water heater repairs.
