Tankless Units in Aurora Homes
In Aurora, basement units with PVC sidewall vents are typical. Scale from the hard water and snow at the termination are the faults we see most.
What we run into in Aurora
- Basement units. Many units here sit in the basement with PVC pipes venting out through the rim joist, and the condensate has to drain somewhere sensible.
- Snow on vents. Snow drifting against a sidewall vent will stop a unit cold with a venting code until the termination is cleared.
- Hard water. Mineral-heavy water coats the exchanger a little more every month. Many repair visits here end with a descale as well, so the fix holds.

Call (380) 273-8196Tankless Problems We Fix Around Aurora
Most requests for tankless water heater repair in Aurora, IL start with one of the symptoms below, and most end with a single part or a descale.

Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.

Water under the unit
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.

Tankless Water Heater Repair in Aurora, IL: FAQs

Call (380) 273-8196How much does tankless water heater repair in Aurora, IL cost?
Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. On hard water, a descale often goes with the repair and sits on the same written quote.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
How often should a tankless water heater be flushed?
Most makers call for a flush every year, and every six months on very hard water. On very soft water the gap can be longer, but skipping it for years invites scale faults.
Why does my tankless water heater go hot then cold?
A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.
