Tankless Units in Temple Hills Homes
In Temple Hills, 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 Temple Hills

- 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 Temple Hills, MD. 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.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
