From washing dishes and laundry to bathing and cleaning, your household relies on having a consistent supply of hot water. Some homeowners have opted for tankless water heaters because this appliance provides an instant source of hot water when it is needed. While this customization can help reduce monthly energy bills, there may come a time when your device experiences problems. Here are some common tankless water heater issues to be aware of.

A Guide to Tankless Water Heater Issues

1. Exhaust and Air Supply Blockage

This will typically occur if the appliance’s vents are obstructed. Depending on the model, the vents’ locations will vary. Pipe holes, cracks, and improper connections may also cause air supply and exhaust blockage. Because insects, rodents, and birds like to build their nests next to vents, check the tank’s surroundings to ensure that these dwellings are not causing obstructions. 

2. Hot Water Overload

If your home has multiple bathrooms, an overuse of hot water can occur, especially when several showers or baths are running at the same time and put a strain on the plumbing. Tankless water heaters may not be able to consistently supply hot water and shut down. Depending on your appliance, you may have to reset it. To prevent overload, stagger hot water use by scheduling showers in the morning and at night. Do laundry once a week instead of several times a week.

3. Mineral Corrosion

Hard water that contains high levels of minerals can build up in a tankless water heater. Over time, the accumulation may cling to the plumbing and cause the unit to malfunction or stop working. To prevent corrosion, your water heater should be professionally flushed to remove minerals every six months or in accordance with the appliance’s recommended time frame. 

4. Inconsistent Temperature and Pressure

The water’s temperature and pressure level should be consistent each time the water heater is used. If you notice unusual changes in either one, the efficiency level may need an adjustment. You can reset the levels according to the water heater’s manual. A professional plumber can complete an inspection and reset the tank to guarantee consistent temperature and water pressure levels. 

5. Strange Odor and Taste

Water used in your household should always be clean, clear, and free of any odors. If you notice a rusty smell or taste, iron might be present in the tankless water heater. A gas leak might be present if you smell rotten eggs. Water testing completed by an experienced plumber will identify the source of strange odors and tastes.
