Copper soft pipes in insulation with cable 10 m Vaillant auroSTEP 302359

Vaillant copper soft pipes in insulation with integrated cable, 10 m length, are flexible copper tubing designed for solar thermal and heating system installations. The product combines pliable copper lines with factory-applied thermal insulation and a bonded electrical conductor to enable sensor or earthing connection. Its construction facilitates routing in confined spaces and reduces heat loss compared with uninsulated runs, making it suitable where both flexibility and basic thermal protection are required.

Advantages

The pre-insulated copper soft pipes reduce installation time by eliminating the need to insulate tubing on site and provide consistent thermal performance along the entire length. Integrated cable saves an additional installation step for sensor or earthing wiring and ensures a reliable mechanical relationship between the conductor and the pipe. The flexible copper core allows bending without kinking for easier routing in solar collector arrays, roof penetrations, or within plant rooms.

Suitable for

• Solar thermal collector connections
• Domestic hot water and heating circuit extensions
• Routing through confined or curved runs where flexibility is needed
• Installations requiring a built-in connection for a temperature sensor or earthing conductor

Key specifications

• Material: flexible copper tubing with external thermal insulation
• Length: 10 metres
• Integrated conductor: bonded cable for sensor or earthing connection
• Insulation type: factory-applied thermal insulation (closed or open cell depends on model)
• Typical applications: solar thermal systems, heating circuits, potable hot water distribution

How to use

Cut the pre-insulated copper pipe to the required length using appropriate tools for copper tubing, taking care not to damage the insulation or the integrated cable. Deburr and prepare pipe ends for fittings according to the chosen connection method. Route the insulated pipe along the planned run keeping bends gentle to avoid kinks in the copper core. Expose the integrated conductor where needed and connect it to the temperature sensor or earthing point following local electrical regulations. Secure the pipe at regular intervals to prevent movement and ensure the insulation remains intact.

Usage recommendations

Verify compatibility of fittings and connection methods with flexible copper tubing and confirm the insulation type meets thermal loss requirements for your installation. Protect exposed pipe sections and connectors from UV and mechanical damage, and follow local codes for earthing and sensor wiring. For long outdoor runs consider additional mechanical protection or conduit where required.
