High Sensitivity 220°C Flat-Angle Thermostat Water Heater Accessory High-Temperature Safety Control Component

Product Overview
This flat terminal bimetallic thermostat is a mandatory safety spare part for wall-mounted tankless gas water heaters. Fixed flat against the heat exchange tank via its dual-hole galvanized flange, it continuously detects real-time surface temperature of the water tank. When water shortage, blocked water pipe or dry burning causes abnormal high temperature, the built-in bimetallic wafer deforms instantly to disconnect the ignition circuit and cut off gas supply, preventing toxic flue gas backflow and fire accidents. Equipped with universal flat quick-connect terminals and heat-resistant insulated housing, it perfectly adapts to long-term humid high-temperature environment inside water heaters, ideal aftermarket replacement part for aged, rusted or contact-failed original thermostats.

Main Advantages
Critical Anti-Dry Burn Safety Lock
Real-time monitor tank surface temperature, cut off ignition power within milliseconds after overheating, eliminate the biggest safety hazard of gas water heaters.

Zero Extra Wiring Processing Required
Flat spade terminals directly plug into matching wiring harness, technicians complete installation without wire stripping, crimping or soldering.

Long Service Anti-corrosion Steel Flange
Whole zinc plating on mounting flange blocks condensed water corrosion, solve rust and poor contact faults of old water heater thermostats.

Heat Isolation Internal Chip Protection
High-temperature resistant plastic shell isolate excessive heat from hot water tank, avoid permanent failure of temperature sensing element.

Wide Universal Market Compatibility
Standard size fits most household natural gas and LPG propane 12L~16L tankless gas water heater models.

Factory Uniform Calibrated Temperature Parameter
Unified standard cut-off temperature, no manual adjustment needed after installation, same sensitivity as OEM original parts.

Installation Tips
Fit the flat surface of thermostat closely to the heat exchanger tank wall, lock two mounting screws evenly to eliminate contact gap for accurate temperature detection.

Insert the wiring harness plug fully onto the flat terminal lugs to avoid air oxidation and poor contact leading to ignition failure.

Do not scratch the galvanized coating on the steel flange during installation to retain anti-rust performance.

Replace the thermostat immediately if plastic shell melts or metal terminals rust severely.
