About water heaters
Water Heater Repair in Chicago: Repair or Replace?
Plenty of water heater problems are a single part: a thermocouple, a gas control valve, a heating element or a thermostat. A technician tests the heater, finds the failed part and tells you whether repair makes sense.
Age decides a lot. Tank water heaters commonly last around 8 to 12 years. A tank that leaks from its body, rather than from a fitting or valve, has rusted through and needs replacing. Water heater installation includes the gas or electrical connection, the relief valve and discharge pipe, and the venting.
In many Chicago homes the water heater vents into the same brick chimney as the furnace or boiler. When either one is replaced, the chimney and vent sizing should be checked, because a water heater left alone in a large masonry chimney may not draft properly.

What’s included
Water Heater Services, Problem by Problem
The water heater calls that come up most in Chicago homes.
Not enough hot water
Sediment taking up space in the tank, a failed lower element, a broken dip tube, or a heater too small for the household.
Leaking water heater
A leak from a fitting or the relief valve is usually a repair. A leak from the tank itself means replacement.
Pilot won’t stay lit
A worn thermocouple, a dirty pilot assembly or a draft problem in the venting.
Popping or rumbling
Sediment at the bottom of the tank. Flushing can help; heavy buildup shortens the heater’s life.
Tankless installation
Endless hot water from a wall-mounted unit. It needs the right gas line size and venting, which the technician checks first.

Tank or tankless
Choosing a Water Heater for a Chicago Home
| Tank | Tankless | |
|---|---|---|
| Hot water | A stored supply, then a recovery wait | Continuous, limited by flow rate |
| Space | Floor space in the basement or closet | Wall-mounted, compact |
| Typical life | Around 8–12 years | Often 15–20 years with descaling |
| Install needs | Usually fits the existing connections and vent | Often a larger gas line and new venting |
Lake Michigan water is moderately hard, so tankless heaters benefit from periodic descaling and tank heaters from an occasional flush. For more, read no hot water: common water heater problems and fixes.
Water heater leaking heavily? Turn off the cold-water valve on top of the heater and turn the gas control to Off (or switch off the breaker on an electric heater). If you smell gas, leave the house and call Peoples Gas or 911 from outside.

Water Heater Questions From Chicago Homeowners
