About Takagi Tankless Water Heater Repair

Takagi produces heavy-duty commercial and residential tankless water heaters built with thick-gauge copper heat exchangers in Evergreen Park, Illinois. When error codes like 111, 121, or 721 flash on the computer board, the system shuts down to protect its internal circuitry. Our technicians understand Takagi electronic logic, dual-temperature thermistor networks, and Hi-Limit switches. We clean ceramic flame rods, test motorized gas control valves, and clear clogged condensate drains. We restore steady, high-output hot water to your Takagi system using authentic manufacturer parts.

What Our Customers Say

Real reviews from property owners we have helped restore to endless hot water.

Our Navien unit flashed error E003 on a cold morning and stopped heating completely. The technician arrived with the exact OEM flame sensor rod on his truck, tested the gas manifold pressure, and had hot water flowing again within an hour. The diagnostic explanation was clear and pricing was fair.

Our Rheem tankless system kept shutting down during showers with code 12. Two other plumbers told us we needed a new unit, but this team discovered a clogged condensate trap and an oxidized flame sensor. They cleaned the burner assembly and saved us thousands compared to a premature replacement.

Hard water scale choked our Rinnai heat exchanger to the point where shower pressure dropped to a trickle. Their technician hooked up a high-volume descaling pump and circulated food-grade solution for over an hour. The difference in water pressure and heating speed was immediate.
