Soft copper pipes DN10, 20 m for the auroSTEP system 302360

Complete installation kit for solar collectors

This solution eliminates the need for separate routing of pipes and cabling, significantly accelerating the installation of solar systems. The kit includes two flexible copper pipes with a diameter of DN10, factory-integrated within a single continuous thermal insulation sheath. This ensures uniform thermal insulation along the entire length and eliminates the risk of errors during on-site insulation installation. The included electrical cable is used to connect temperature sensors, enabling full automation of the system operation without the need for additional drilling or separate signal lines.

The 20-meter length makes the kit ideal for typical residential installations where the distance between the roof and the storage tank does not exceed this value. The flexible pipe construction facilitates installation in hard-to-reach areas and allows easy adaptation to existing building infrastructure. The kit is dedicated to the auroSTEP system, ensuring full compatibility with other components of this Vaillant product line.

What does the kit include and how does it simplify work?

The product is designed so that the installer has everything needed for quick commissioning of the solar circuit at hand. There is no need to purchase separate mounting elements or connections – they are already included in the packaging.

• Pre-insulated pipes: The pipes are factory-fitted with thermal insulation sheathing, protecting the working fluid from heat loss in winter and overheating in summer.
• Integrated cable: The electrical cable running inside the sheath simplifies sensor wiring, reducing the number of penetration points through walls or the roof.
• Mounting components: The kit includes 4 oval-clamp brackets for DN10, allowing secure fixation of the pipes along their entire route.
• Connections: The kit contains the necessary connection elements enabling direct connection of the pipes to solar collectors and the buffer tank.

Application and benefits for the installation

This pipe arrangement is particularly recommended for modernizing existing systems or building new "plug-and-play" solar installations. The flexible copper pipe allows easy navigation around architectural obstacles without the need for elbows or welded fittings at every bend – the pipe can simply be bent manually or using a bending spring (recommended for copper).

The flexible copper pipe enables bending without welding tools even on complex routes, significantly reducing installation time. Integrating two pipes with a cable eliminates the need to join insulation and cables separately, reducing assembly time by approximately 30-40%. The 20-meter length is sufficient for most single-family homes, covering the distance from the roof to the boiler room without the need for joining sections. Oval brackets ensure tight and aesthetic pipe fixation within the insulation, eliminating the risk of damaging the copper pipe through compression.

Thanks to this solution, the installer receives a ready-made "energy-thermal cable" that, once laid out and secured with brackets, forms a complete solar circuit. The end customer gains confidence that the pipes are properly insulated from the moment of purchase until final installation, resulting in higher efficiency of the entire solar-based heating system.
