Before assuming the worst, check the basics. For electric water heaters, check the breaker panel — a tripped breaker cuts power entirely. Most electric units also have a red reset button near the upper thermostat that trips if the water gets too hot; press it once. For gas units, check whether the pilot light is lit; if it keeps going out, that often points to a failing thermocouple.
Florida's hard water deposits minerals inside the tank faster than in most of the country. Over years, that sediment settles at the bottom and can build up thick enough to insulate the burner or lower heating element from the water above it — the unit runs, but heat never effectively transfers. This is one of the most common causes of "no hot water" complaints we get, and it's largely preventable with periodic tank flushing.
Electric tanks have one or two heating elements. If the lower element fails, you might get lukewarm water for a short time before it runs cold; if the upper element fails, you may get no hot water at all. A multimeter test confirms which element has failed, and replacement is usually straightforward.
The thermocouple is a safety sensor that shuts off gas flow if it doesn't detect a lit pilot. When it fails, the pilot won't stay lit even though gas is available. It's an inexpensive part and a common repair. A failed gas valve is less common but more involved to replace.
If your water heater is over 8 to 10 years old and multiple components are failing, or the tank itself shows rust or a leak at the base, repair often isn't the better value anymore. We'll tell you honestly which situation you're in.
