Plumber Interview Question:

Explain me one downside of a conventional water heater. Would you suggest an alternative?

Submitted by: Muhammad

While the conventional water heating system is in a league of its own, the fact that energy is being consumed constantly is a definite downside to using one. If saving energy is what a client wants, then I would suggest a tank-less water heater that uses energy only when there is a requirement for hot water.
