Do tankless water heaters get calcium buildup?

The heat energy in the tankless water heater separates the calcium from the water, creating calcium deposits that can accumulate on the heat exchanger. Over time, if no action were taken, that buildup would make heat transfer more difficult, straining the water heater and reducing its lifespan.
