How does a water heater work?
Conventional storage tank hot water heaters utilize a 100-year-old design. Cold water is delivered to the bottom of an insulated tank where it’s heated by an external burner fueled by natural gas. Heated water rises to the top of the tank and exits through an outlet pipe to be distributed to hot water taps throughout the home on demand. So what could go wrong? Not too much, actually. That’s why this simple design’s lasted so long. However, when good water heaters go bad, the most frequent complaint is also the most fundamental: no hot water. This can arise from mistakes or malfunctions, most of which are easy to trace. Not all lend themselves to do-it-yourself repairs, however. Malfunctions that involve flammable natural gas require the services of a professional plumber.
