High-Efficiency Underfloor Heating System with Superior Thermal Conductivity
Structure & Technology
| Component | Material | Function |
|---|---|---|
| Base Material | Cross-linked Polyethylene (PEX) | Flexibility, durability, chemical resistance |
| Functional Layer | Graphene-Enhanced Composite | Superior thermal conductivity, uniform heat distribution |
The graphene additive is uniformly dispersed throughout the pipe structure, creating a continuous thermal pathway that accelerates heat transfer from the circulating fluid to the floor surface.
Key Advantages
Superior Thermal Conductivity – Graphene integration increases heat transfer efficiency by up to 30–50% compared to standard PEX pipes, enabling faster room temperature response and reduced energy consumption.
Energy Efficiency – Improved heat transfer allows lower water temperatures to achieve desired comfort levels, reducing boiler or heat pump operating costs and supporting sustainable building designs.
Uniform Heat Distribution – Enhanced thermal conductivity ensures consistent surface temperatures across the floor, eliminating cold spots and improving occupant comfort.
Full Flexibility – Retains all mechanical advantages of PEX, including flexibility for tight bends, long continuous runs without fittings, and compatibility with standard PEX installation methods.
Oxygen Barrier Protection – Available with EVOH oxygen barrier layer to prevent oxygen diffusion into the system, protecting metal components (boilers, pumps, manifolds) from corrosion.
Durability – Resistant to creep, chemical attack, and freeze damage. Designed for service life exceeding 50 years in radiant heating applications.
