The type of water heater that most homeowners are familiar with is the tank model. They’re big, often noticeable, and maybe even a little bit noisy depending on where you have it on your property. This is the conventional water heater, and most people know that it needs maintenance in order to prevent scaling—the buildup of hard water minerals that cause problems with pressure, corrosion, and temperature settings.
What many people don’t realize, however, is tankless water heaters need care for the same reason, pretty much. So if you have a tankless system or if you’re debating getting one, it’s important to know that maintenance will still be a necessary part of your life. Otherwise, scaling could lead to various problems, not excluding premature replacement.
