Bimetallic Strip in Electric Water Heater

Within an electric-water-heater thermostat assembly, the bimetallic strip in electric water heater senses temperature and creates a mechanical deflection that can work with a support, contact or actuator mechanism for temperature control or overheat protection. The strip is a core component rather than a complete switching device, and its actual behavior is influenced by mounting position, heat-transfer path, fixing pressure and the design of the complete thermostat.

The bimetallic strip in electric water heater can be selected with operating temperatures from 40-100°C and reset temperatures from 0-60°C, with a ±5°C temperature tolerance. Salt-spray testing can be arranged for 24, 48 or 72 hours. The source specification does not define whether the part is round, slotted or irregular and does not provide a universal thickness, diameter or movement value, so dimensions must be confirmed from customer drawings, existing samples or the thermostat assembly.

Gan'en Electronics can handle bimetal stamping, forming, heat treatment and finished thermostat assembly. The process-engineering team can review shape, temperature range and mounting method for electric water heaters with different capacities, power ratings and sensing locations. The usual MOQ is 10,000 pcs. Standard samples are free before bulk production; standard items generally require about 7 days and custom items about 15 days.

OEM, ODM and drawing-based production are supported for the bimetallic strip in electric water heater. Products with several sensing points or multiple heater capacities can be separated by drawing and specification number. Manufacturing control covers incoming, in-process, semi-finished/finished and outgoing inspection plus after-sales traceability, followed by complete inspection before packing and support for third-party inspection to keep repeat batches consistent.
