The Viessmann DHW (Domestic Hot Water) Cylinder Temperature Sensor – NTC 10k is a high‑precision sensor designed to accurately measure the temperature within an indirect hot water cylinder. Using a 10kΩ NTC (Negative Temperature Coefficient) thermistor, this sensor provides fast and reliable readings to the boiler or control system, ensuring consistent hot water production and optimal energy efficiency.

This sensor plays a key role in modulating boiler operation for DHW demand, helping maintain stable cylinder temperatures while preventing overheating or energy waste. Built from durable, heat‑resistant materials, the NTC 10k sensor offers long‑lasting performance and dependable operation within a wide range of Viessmann domestic hot water systems.
