Temperature Sensor for Domestic Hot Water INSIZE P0431 KTF20

Temperature Sensor for Domestic Hot Water INSIZE P0431 KTF20 is a compact immersion probe designed to measure and monitor hot water temperature in residential and commercial installations. The sensor provides stable, accurate readings suited for boiler regulation, circulation loop monitoring and routine maintenance tasks. Its form factor and mounting arrangement make it suitable for integration with hot water tanks, circulation lines and heating control equipment where a dedicated hot-water temperature probe is required.

Advantages

The sensor delivers consistent temperature measurement with a design optimised for domestic hot water environments. Its compact probe body and straightforward mounting reduce installation time and simplify replacement in existing systems. The product is compatible with common heating and control systems and supports reliable feedback for thermostatic regulation and pump control. The construction is intended for long-term use in hot-water circuits, minimising the need for frequent recalibration when used within recommended operating conditions.

Suitable for

• Temperature monitoring of domestic hot water (c.w.u.) tanks and cylinders
• Boiler temperature feedback for control and regulation systems
• Circulation loop monitoring in residential and light-commercial installations
• Routine maintenance checks and system diagnostics

Key specifications

• Type: Immersion temperature probe for domestic hot water
• Measurement medium: Hot potable water and circulating heating water
• Probe design: Compact cylindrical probe suitable for sleeve or direct immersion
• Compatibility: Designed for integration with heating controllers, boiler systems and circulation pumps
• Typical installation environment: Domestic and light-commercial hot water systems

How to use

Install the probe in a dedicated sensor pocket, immersion sleeve or secure it directly in the flow/return line where permitted by system design. Connect the sensor wiring to the control unit following the controller manufacturer’s connection diagram and ensure proper polarity where applicable. Allow the system to stabilise after installation and verify displayed temperature values against a reference thermometer if accuracy check is required. Tighten fittings and confirm there are no leaks in the sensor mounting area before returning the system to normal operation.

Usage recommendations

Place the sensor where representative flow temperature is available and avoid mounting immediately adjacent to heat sources that do not reflect bulk water temperature. Where possible, use a protective sleeve for easier replacement, and follow the heating system manufacturer’s guidelines for sensor placement and wiring to ensure accurate control performance and long-term reliability.
