What Roanoke Does to a Tankless Heater
Roanoke heaters often sit in a basement or a utility room at crawl-space level. They make it through winter as long as the condensate line stays clear and freeze protection keeps working.
Local factors in Roanoke
- Basement heaters. With a basement heater, a plugged condensate trap or a dead pump can shut things down with a code well before any puddle shows up.
- Winter freezes. A deep freeze can burst the lines that supply a heater. The built-in freeze protection does its job only as long as it has electricity and gas.

Call (888) 987-0567Tankless Trouble We See in Roanoke
Most tankless water heater repair in Roanoke, VA calls trace back to one of the faults below, and the code on the panel usually narrows it down.
Clicks, but no flame
Clicking with no flame means something in the gas, ignition or vent path is off. We work through all three.
Dripping from the cabinet
Where the water comes from decides the bill: a valve or a joint is minor, a failed exchanger is not.
Air supply or exhaust fault
The burner shuts down on an air or exhaust fault to keep you safe. We clear and inspect both intake and exhaust.
Only one faucet runs cold
Typically a worn mixing cartridge or a crossover at that fixture, rather than the heater itself.
Rinnai showing LC
That's the scale warning. The exchanger is due for a descale, and it shouldn't wait long.
No hot water after a freeze
A supply line froze, or the heater lost electricity and its freeze protection with it.

Keep It Running or Replace It in Roanoke?
Flow sensors, igniters, blowers, flame rods, gas valves and control boards are sensible repairs on nearly any heater. The real decision comes when an aging unit's heat exchanger cracks or leaks, since that single part can cost close to a new heater.
Grab the model and serial numbers from the rating plate and ring (888) 987-0567. Age plus symptoms is usually enough to settle the repair question over the phone.

Depending on which part failed, most repairs run an estimated $150–$800. Expect an estimated $150–$350 for a stand-alone descale and an estimated $1,000–$2,500 for a replacement heat exchanger. Freeze damage is priced once we see what cracked, since no two splits are alike.
What is the typical lifespan of a tankless water heater?
Gas units that get regular flushes often last two decades or more. Electric models usually manage somewhere around 7 to 10 years of service.
What usually goes wrong with tankless water heaters?
Scale in the heat exchanger tops the list, then ignition faults, then flow sensor and inlet screen problems. Each usually announces itself with an error code or with water that runs hot and then fades.
Do tankless water heaters have a reset button?
Usually by power: turn the heater off, wait a moment, turn it back on. That clears the code, but if it returns, a component needs attention.
