Water Heater Thermistor

Thermistors for Water Temperature Control

In gas water heaters, precise control of inlet water temperature and hot water outlet temperature is essential for ensuring both safety and user comfort.

Shibaura Electronics’ thermistor sensors provide fast-response and highly accurate liquid temperature measurement, enabling stable hot water delivery and efficient combustion control.

In heat pump water heaters, accurate temperature management is critical for maintaining high-efficiency operation and optimizing heat exchange and heating control processes.

Through highly accurate temperature sensing, our thermistor sensors contribute to efficient system control and stable long-term performance.

For both gas water heaters and heat pump water heaters, we can provide optimized sensor specifications tailored to installation environments and equipment requirements. We also offer flexible support for customized solutions and mass-production applications.

Shibaura Electronics’ thermistor sensors offer the following features ideally suited for gas water heater and heat pump water heater applications:

  • Highly responsive and accurate temperature sensing of inlet water, hot water outlet, stored hot water, and heat exchangers enables stable and precise hot water temperature control.
  • Rapid response to water temperature fluctuations caused by changes in flow rate and operating conditions supports efficient combustion control and high-efficiency heat pump operation.
  • Excellent heat resistance and long-term stability for high-temperature water and extended operating periods. Sensor designs can be customized with protective structures and terminal specifications optimized for pipe diameters, insertion locations, waterproofing requirements, and insulation conditions.
