Descaling service usually costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

Flow Sensor and Thermistor Repair in Palm Bay
Tankless heaters use flow sensors to start and thermistors to regulate temperature.

Temperature becomes steady again once readings are correct.
