What Crofton Does to a Tankless Heater
Crofton 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 Crofton
- Basement heaters. Basement installs are typical locally, often condensing heaters that send acidic condensate to a lift pump or straight into a floor drain.
- Winter freezes. Built-in freeze protection guards the heater's internals, not the bare piping below it. Lines left uninsulated are where most winter damage begins.

Call (888) 987-0567Tankless Trouble We See in Crofton
Nearly every request for tankless water heater repair in Crofton, MD starts with a symptom on this list and finishes with a single replaced component or a flush.

No-ignition code (11, E003, 111)
Clicking with no flame means something in the gas, ignition or vent path is off. We work through all three.

Dripping from the cabinet
Leaks start at service valves, pipe joints, the pressure relief valve, the condensate drain or a cracked exchanger.

Code 10 or E110 on the panel
A venting code means the heater can't move air: a blocked cap, a bird or wasp nest, drifted snow or an overlong vent.
Temperature swings in the shower
A few seconds of cool water when a tap reopens is how these heaters start up. Swings mid-shower suggest low flow, scale or a weak flow sensor.
Cuts out partway through a shower
Flow has fallen under the firing minimum, usually from a plugged screen, aerator or shower valve cartridge, or a sensor reading low.
Only one faucet runs cold
Typically a worn mixing cartridge or a crossover at that fixture, rather than the heater itself.

Keep It Running or Replace It in Crofton?
