Water Heater Repair in Darien, IL
86% of households in Darien heat with gas. 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
Darien runs on gas: 86% of households heat that way, and that single fact rules most of the possible water heater faults in or out. The figure covers house heating rather than the tank. A gas unit fails at the pilot, the thermocouple, the gas control valve, or a flue that will not draft.

What Darien runs on
Gas is clearly in front here. The useful consequence is that the fault list is short: pilot, thermocouple, gas valve, and eventually the flue.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 86% |
| Electricity | 14% |
| Fuel oil and kerosene | 0% |
| Everything else | under 1% |
Drawn from table B25040 of the US Census Bureau's American Community Survey, 5-year estimates, 2023 release — 9,278 occupied housing units across Darien.
On gas, Darien is close enough to the Illinois figure that the difference is inside the survey’s margin of error — so the state pattern is a fair guide here, which is not true everywhere.
Read that as a strong indicator rather than a measurement of water heaters. The Census counts what heats the house; what heats the water usually follows it, and occasionally does not.
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. Establish the fuel first; almost every useful question after that depends on it.
Then match what you are seeing: cold from the start, hot then cold, banging and popping, or a leak.
