Lochinvar L100208549 Inlet Sensor Condensing Water Heater

Product Description

The LOCHINVAR L100208549 is a replacement inlet sensor designed for use with Armor X2 1000 to 1500 condensing water heaters. This sensor monitors incoming water temperature and feeds that data to the unit's control system, allowing the heater to regulate combustion and output efficiently. Accurate inlet temperature sensing is critical to the proper operation of condensing water heaters, where the control strategy depends on real-time temperature differentials. Licensed plumbers and commercial HVAC technicians are the typical trade professionals handling this replacement on large-capacity commercial water heating systems.

This inlet sensor is specified for the Lochinvar Armor X2 condensing water heater in the 1000 to 1500 MBH capacity range. These units are commonly installed in commercial and light-industrial applications where high-volume domestic hot water demand requires dependable, high-efficiency equipment. Replacing a failed or out-of-spec inlet sensor restores accurate temperature feedback to the control board and ensures the system operates within its designed efficiency and safety parameters.
