Plumbing Guide

Tank vs Tankless Water Heater: A Centennial Guide

The tank

A tank heater stores hot water and is always ready, but it keeps reheating that water even when nobody needs it. It costs less up front and is simple to install.

The tankless

A tankless heater heats water on demand, so it never runs out and wastes no standby heat. It costs more to install but lasts longer and saves energy over time.

The demand

A large household that uses several showers at once may need a big tankless or two units, while a small household can thrive on either. freezing winters and hard water are both common, and older homes often have aging supply lines In Centennial, cold incoming water affects how well a tankless keeps up.

The space

Tankless units hang on the wall and free up floor space, which matters in a tight mechanical closet or a condo.

The long run

Tankless costs more up front but can last years longer and saves energy daily. The right answer depends on how long you will stay in the home.
