Most homeowners can, and should, routinely clean and inspect their tankless water heaters. Here are three things you can do to keep your unit operating correctly—check your owner’s manual for instructions specific to your model:
- Perform a tankless water heater flush at least once every year. If you have especially hard water, more frequent flushes will protect your unit from mineral buildup.
- Some tankless models have air filters or cold-water inlet filters, which must be cleaned regularly to prevent a reduced flow of water.
- Clean the exterior cabinet of the unit (but not the fan blades, heat exchanger, or burner) with a damp cloth. This will allow you to perform a more effective visual inspection of the unit. If you see any signs of rust, call your local Mr. Rooter Plumbing for assistance.
