Tankless Units in Kannapolis Homes
In Kannapolis, units are often retrofits on older homes. Ignition faults and frozen lines after a cold snap are the common repairs.
What we run into in Kannapolis
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.
- Retrofit installs. Retrofits are common in this housing stock. When a unit throws flame codes only while the furnace or dryer runs, the gas supply is the first suspect.

When people phone about tankless water heater repair in Kannapolis, NC, it is nearly always one of these problems. Each has a short list of causes.
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
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.
Venting fault
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.

Why is my tankless water heater not turning on?

Many do it through power: switch the unit off, wait, switch it back on. That clears a code, but a code that comes back means a part needs attention.
