Water Heater Repair in Cumberland Furnace, TN
72% of households in Cumberland Furnace heat with electricity. That is the strongest free clue to what kind of water heater is in your basement, and it decides which faults are even possible.
Answer first
Most households in Cumberland Furnace heat with electricity — 72% of them — which is the strongest free clue to what stands in the basement, though the figure counts house heating rather than the water heater itself. An electric unit has two elements and two thermostats and no pilot that can go out.

Tennessee statewide runs 17 points lower on gas, so this town is not typical of it.
One caveat, because it matters: the Census measures the fuel a household heats the HOUSE with, not the fuel it heats WATER with. The two track each other closely — a gas line to the furnace usually feeds the tank as well — but they are not the same number.
Which one do you have
If you are not sure, look at the top of the tank: a flue pipe going up into the ceiling means gas, and no flue at all means electric. The fuel decides the fault list, so start there rather than with the symptom.
Then match what you are seeing: cold from the start, hot then cold, banging and popping, or a leak.
