Skipping maintenance can make your water heater less efficient, reduce water quality, and even shorten its lifespan. Regular maintenance includes flushing the system to get rid of mineral buildup, checking the combustion system, and inspecting the venting.

  • No appliance lasts forever, and tankless water heaters are no different. If your water heater starts acting up, it can lead to costly repairs and safety concerns. In some cases, like when the tank is leaking or the control panel is broken, you might need a replacement.

Tankless Water Heater Maintenance Tips

If you're a homeowner with a tankless water heater, you can do some simple maintenance to keep it running smoothly. Here are three things you should consider (always check your owner's manual for specific instructions):

  1. Annual Flush: It's a good idea to give your tankless water heater a flush at least once a year. If you have really hard water, you might need to do this more often to prevent mineral buildup.
  2. Filter Cleaning: Some tankless models have filters for air or cold water intake. Be sure to clean these filters regularly to keep the water flowing strong.
  3. Exterior Cleaning: Use a damp cloth to clean the outside of the unit (just avoid cleaning the fan blades, heat exchanger, or burner). This helps you spot any rust or issues. If you see rust, don't hesitate to contact your local Mr. Rooter Plumbing for assistance.

Frequently Asked Questions

  • Traditional water heaters are normally made up of large storage tanks of about 49-50 gallons or even more and are heated constantly. These tanks are mostly used to accumulate a large amount of hot water to serve the households. Whenever these traditional water heaters are been exhausted, it takes a lot of time to refill and reheat them.

    No need for a water storage container since tankless water heaters warm up the water as it passes through. The tankless water heater circulates cold water around a heat exchanger thereby turning the cold water into heated water and sending it to your home through the pipes.
