Tankless Units in Lorton Homes
In Lorton, units are often in a basement or crawl-space-level utility room. Freeze protection and a clear condensate line keep them running through winter.
What we run into in Lorton
- Basement units. Basement installs are common, often condensing units whose acidic condensate runs to a floor drain or a small pump.
- Freeze damage. Freeze protection keeps the inside of a unit safe, not the exposed pipes under it. Uninsulated lines are where winter damage usually starts.

These are the faults behind most calls for tankless water heater repair in Lorton, VA. The display usually points at one of them.
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.

Fix It or Retire It? Deciding in Lorton
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.
Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.
