Tankless Units in Winston-Salem Homes
Many Winston-Salem homes are brick ranches where the tankless went onto an outside wall or into the garage. Occasional hard freezes and gas supply sizing cause most of our calls.
What we run into in Winston-Salem
- 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.
- Retrofit installs. Plenty of units here were fitted into older homes after the fact, and an undersized gas line or a long vent run can cause ignition faults years later.

The list below covers what we find on most visits for tankless water heater repair in Winston-Salem, NC, from ignition codes to drips under the cabinet.
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.
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.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
