The following types of pipes are commonly used for underfloor heating systems:
1. Cross-linked Polyethylene (PEX)
PEX pipes are widely used for underfloor heating due to their flexibility, durability, and resistance to high temperatures. They are available in different sizes and can be installed using various methods.
2. Polybutylene (PEX-B)
PEX-B pipes are another option for underfloor heating systems. They are flexible, easy to install, and have good resistance to high temperatures.
3. Polyethylene (PE-RT)
PE-RT pipes are similar to PEX pipes but have enhanced temperature resistance. They are suitable for underfloor heating systems that require higher operating temperatures.
4. Multilayer Composite Pipe
These pipes consist of multiple layers, typically with an aluminum core and an inner layer of PEX or PE-RT. Multilayer pipes offer excellent heat transfer and are often used in underfloor heating installations.
5. Copper
Copper pipes have been used for underfloor heating in the past, but they are less common nowadays due to their higher cost and the popularity of PEX and other alternatives. Copper pipes provide good heat transfer properties but require skilled installation.
It’s important to consult with a professional heating specialist or plumber to determine the most suitable type of pipe for your specific underfloor heating system, considering factors such as budget, installation method, and design requirements.
