Flow Sensor and Thermistor Repair in Springfield
Tankless heaters rely on flow sensors to start and thermistors to regulate temperature.

Temperature becomes steady again once readings are accurate.

Condensing Tankless Repair in Springfield, MO
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate.

PVC venting is also inspected for slope and sagging.

Modern tankless water heaters display error codes to indicate specific problems, from flow rate issues to combustion errors.
