Water Heater Repair in Markham, IL
96% of households in Markham 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
96% of Markham households burn gas for heat, and a water heater almost always sits on whatever line the furnace already uses. That is house heating fuel, so read it as a strong hint rather than as a reading of your own tank. A gas unit fails at the pilot, the thermocouple, the gas control valve, or a flue that will not draft.

What Markham runs on
With gas clearly in front, most tanks here burn it. That puts the usual faults on the burner side — pilot, thermocouple, gas valve — rather than on elements and thermostats.
| Fuel | Share of households |
|---|---|
| Gas — mains and bottled | 96% |
| Electricity | 3% |
| Fuel oil and kerosene | 0% |
| Everything else | 1% |
US Census Bureau, American Community Survey, table B25040, 2023 5-year release. The universe is 3,655 occupied housing units in and around Markham.
The Illinois average is 14 points higher, so the state figure would mislead you about this town.
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. Settle that one question and the rest of the conversation is straightforward.
The symptom does the rest of the work. Hot water that quits early is the most informative of them; a leak from the tank itself is the most urgent.
