Tankless Units in Homer Glen Homes
In Homer Glen, 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 Homer Glen
- 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. After a big storm, a buried intake or exhaust is one of the first things to check when the hot water quits.
- Hard water. Scale is the slow problem in this area: it narrows the waterways, trips temperature limits and shortens the life of the exchanger if nobody flushes it.

When people phone about tankless water heater repair in Homer Glen, IL, it is nearly always one of these problems. Each has a short list of causes.

Unit won't light
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

Drip from the cabinet
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.
