Imagine a world where hot water is always available at the perfect temperature, whether at home or in a commercial setting. This convenience is made possible by advanced temperature sensors like NTC thermistors and PT100/PT1000 RTDs. In this blog, we’ll explore how these sensors are used in household instant hot water dispensers and commercial hot water systems, and how Nanjing Shiheng’s products can enhance their performance.

The Importance of Temperature Control in Hot Water Systems

Hot water systems, whether for household or commercial use, rely on precise temperature control to:

 Ensure Safety: Prevent overheating and potential hazards.

 Optimize Energy Efficiency: Maintain ideal temperatures to reduce energy waste.

 Extend Equipment Lifespan: Minimize thermal stress on components.

To achieve these goals, temperature sensors like NTC thermistors and PT100/PT1000 RTDs are integrated into the systems.

 NTC Thermistors in Household Instant Hot Water Dispensers

NTC thermistors are the go-to solution for household instant hot water dispensers due to their high sensitivity, fast response, and cost-effectiveness. Here’s how they work:

1. Temperature Sensing: 50k ohm NTC thermistors are placed near the heating element or water flow path to detect temperature changes. As the temperature increases, the thermistor’s resistance decreases, providing a real-time signal to the control unit.

2. Inrush Current Limiting: When the dispenser is turned on, a sudden surge of current (inrush current) can damage the heating element. An Inrush Current Limiter (often an NTC thermistor) is used to suppress this surge, protecting the system and extending its lifespan.

3. Temperature Control: The control unit uses the thermistor’s signal to adjust the heating element’s power, ensuring the water reaches and maintains the desired temperature.

4. Safety Features: If the temperature exceeds safe limits, the thermistor triggers a shutdown or alarm, preventing overheating and ensuring user safety.

 PT100/PT1000 RTDs in Commercial Hot Water Systems

For commercial hot water systems, PT100 and PT1000 RTDs are preferred due to their high accuracy, wide temperature range, and long-term stability. Here’s how they are used:

1. Precise Temperature Measurement: PT100/PT1000 sensors provide highly accurate temperature readings, essential for largescale systems where consistency is critical.

2. Durability: These sensors are designed to withstand harsh environments, making them ideal for commercial applications.

3. Integration: PT100/PT1000 sensors can be easily integrated into industrial control systems, providing reliable data for automated temperature regulation.
