The outlet thermistor on a Rinnai 1500i/e continuous flow water heater measures the temperature of the water leaving the appliance, feeding that reading to the control system so it can regulate output accurately. Without a reliable reading here, the appliance has no dependable way of knowing whether it's delivering water at the correct temperature.
A worn or faulty outlet thermistor doesn't just risk inaccurate hot water temperature — it can also cause the appliance to work harder than it needs to, increasing energy use and adding unnecessary strain over time. This genuine Rinnai outlet thermistor, made to the original specification, restores accurate temperature sensing so the appliance regulates output correctly and runs at its intended efficiency.
⚠ Important: This part must be installed by a Gas Safe registered engineer to ensure safe operation and compliance. Always isolate the gas and electrical supplies before starting work.
If your 1500i/e is delivering inconsistent water temperature or seems to be working harder than it should, the outlet thermistor is a sensible first check — it's the sensor the control system relies on to regulate output accurately. This genuine part restores that accuracy, supporting both correct temperature delivery and efficient running.
