Tank water heaters are probably what you’re most familiar with when we mention these systems. They’re large, noticeable, and oftentimes can be a bit noisy. This is the traditional water heater model found in most homes, so many people realize that they need maintenance from time to time.
Scaling is something that occurs in these systems and allows for a mineral buildup that clangs around noisily. This can actually hurt the system—casing problems with pressure, temperature, and potentially even corrosion. Tank water heaters need flushing on occasion to offset all this.
With this knowledge, you may be tempted to switch to a tankless model, and this is certainly worth your consideration. Tankless water heaters are highly efficient, work “on-demand” rather than storing hot water and risking standby energy loss, plus they save space! But, guess what? They need maintenance too.
