Tankless Units in Hockessin Homes
Most Hockessin homes keep the tankless in the basement or a utility room, with the vent through the side wall. Winter cold snaps and condensate drains cause the usual trouble.
What we run into in Hockessin
- Basement units. In a basement install, a clogged condensate trap or a failed pump can shut the unit down with a code long before anyone sees water.
- 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.

The list below covers what we find on most visits for tankless water heater repair in Hockessin, DE, from ignition codes to drips under the cabinet.
Code 11, E003 or 111
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
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
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.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.

Fix It or Retire It? Deciding in Hockessin
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.
Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.
