Water Heater Thermostat Switch 30–80°C Push-In Temp Controller

Gmarty Push-In Water Heater Thermostat Temperature Controller Switch (30–80°C)

Keep your electric water heater running efficiently and safely with this precision plug-in push thermostat from Gmarty. Designed as a direct replacement for Ariston and similar household water heater units, this temperature controller switch automatically manages the heating cycle — turning the heater on when water cools below the set point and shutting it off once the target temperature is reached. Built from durable metal and brass, it is engineered for long-lasting, reliable performance.

How It Works

Once installed and connected, the thermostat continuously monitors water temperature. When the water falls below your preset level (anywhere from 30°C to 80°C), the switch closes and heating begins. As soon as the water hits the target temperature, the switch opens automatically and heating stops — saving energy and protecting your appliance from overheating.

A built-in overtemperature protection circuit triggers at 95°C (±5°C) as a safety backup. The complete temperature control system integrates a power supply circuit, leakage protection circuit, temperature control circuit, water level indication, and anti-dry circuit for comprehensive appliance protection.
