Usage
Designed for EcoSmart tankless electric water heaters, this thermistor is suitable for a variety of installation environments, including new construction, retrofits, and replacement scenarios. It works seamlessly with 18 kW, 24 kW, and 27 kW heater models, providing accurate temperature feedback that enables the heater’s control board to modulate power output efficiently. Whether the heater is installed in a residential kitchen, a commercial office breakroom, or a small‑scale industrial setting, the thermistor’s robust construction ensures reliable operation under fluctuating water flow rates and temperature demands. The inlet and outlet wires are pre‑terminated with standard connectors, allowing quick attachment to the heater’s flow meter terminals. This feature is especially valuable for technicians who need to minimize downtime during service calls. The thermistor also performs well in environments with limited ventilation, as its low power consumption generates minimal heat beyond the measured water temperature.
