Pre-insulated pipe – a comprehensive solution for central heating and domestic hot water installations

Uponor Ecoflex Quattro pipe is an advanced solution that combines heat and domestic hot water transport and circulation in one, flexible system. It is an ideal solution for both extensive networks and single building connections. The construction with four inner pipes – two for hot water and two for heating – ensures convenience and installation efficiency. This means that instead of several separate pipes, you only need one, which simplifies installation and reduces costs.

Construction and properties

The Ecoflex Quattro pipe consists of several key elements that ensure its reliability and durability. The inner pipes are made of cross-linked polyethylene (PE-Xa), which guarantees resistance to high temperatures and pressure. The pipe construction itself is flexible and self-compensating, making it easier to lay even in difficult terrain conditions. The insulation layer made of closed-cell PE-X foam minimizes heat loss, ensuring the energy efficiency of the system. The whole is surrounded by a corrugated outer jacket made of polyethylene (HDPE), which protects the pipe from mechanical damage and weather conditions.

It is worth noting the thermal conductivity coefficient at the level of 0.04 W/(m.K), which proves the high efficiency of thermal insulation. The maximum working pressure is 6 bar for heating and 10 bar for domestic hot water, and the maximum short-term medium temperature is 95°C. The pipe also has certificates confirming compliance with safety and quality standards, including resistance to SLW 60 loads.

Application and benefits

The Uponor Ecoflex Quattro pipe finds wide application in residential and commercial construction:

• Transport of heat and domestic hot water in underground networks.
• Connection of residential buildings to the district heating network.
• Low-temperature installations.
• Chilled water networks.
• Underfloor heating systems.

Thanks to its construction, it offers a number of benefits:

• Economy: one solution for two media – heating and domestic hot water.**
• Energy saving: high thermal insulation minimizes heat loss.**
• Easy installation: the flexibility of the pipe makes it easier to lay, and the Uponor Wipex connection technology eliminates the need for complicated tools.**
• Durability: high-quality materials ensure a long system life.**
• Resistance: to corrosion and weather conditions.**
• Safety: compliance with European standards EN15632 and ISO 9001/14001 confirms the high quality of the product.**
• Versatility: Can be used in various types of heating and plumbing installations.**

The minimum bending radius of the pipe is 1000 mm, which allows it to be adapted to the specifics of the installation without the risk of damaging its structure. The white color of the inner pipes makes it easier to identify individual circuits during installation and subsequent system maintenance.
