Underfloor Heating Pipe

Underfloor heating is widely used in northern Europe and has in recent years become quite popular in the UK, both for new builds and updating existing property. Pipes used for hot and cold water services, often referred to as 'Standard Pipes', are normally single layer extrusions. For central and underfloor heating/cooling applications and embedded coil technology applications it is essential to specify a 'Barrier Pipe'.

Such pipes need to incorporate an internal oxygen barrier. Oxygen barrier pipe is not required in potable water applications. There are numerous manufacturers of underfloor heating equipment producing various types and sizes of underfloor heating pipe and this section explains more about the different types.

Polybutylene Underfloor Heating Pipe

Polybutylene is produced from crude oil by refining and polymerisation. The polymer is extruded to create the finished pipe. Polybutylene underfloor heating pipe is non-corrosive, resists frost damage and is unaffected by hard, soft or aggressive water conditions.

Pex-Al-PE Underfloor Heating Pipe

The components of this underfloor heating pipe are Cross-Linked Polyethylene, Aluminuim barrier, Polyethylene. Cross-Linked Polyethylene (PEX) undergoes a process in which additional unions between the polyethylene molecule chains are formed. This yields a material with much higher resistance to heat and pressure when compared to ordinary polyethylene.

Pex-Al-PE underfloor heating pipe has not had the inside layer of the pipe treated and it remains as standard Polyethylene. The production process is generally shorter with subsequent production costs lower and this is often reflected in the final price.

Pex-Al-Pex Underfloor Heating Pipe

In Pex-Al-Pex underfloor heating pipe, both the inner and outer layers are made of cross-linked polyethylene (PEX). This improves their behaviour in comparison with non-cross-linked multilayer pipes. PEX is the ideal material for multilayer pipes working in applications where high temperatures are required (up to 95°C), such as heating applications.

PEX/AL/PEX multilayer pipes have superior performance with regard to connection viability. Multi-layer pipes based on cross-linked polyethylene (PEX/AL/PEX), ensure that the compression force at the union is maintained even at high temperatures (over 95°C).

PEX-b EVOH Oxygen Barrier Underfloor Heating Pipe

Pex B underfloor heating pipe is produced from cross-linkable, high density polyethylene resin. This cross-linkable resin is produced by grafting organo-silane molecules onto a base polyethylene chain. A catalyst that initiates the cross-linking process is blended with the resin before extrusion. Cross-linking is completed after extrusion by exposing the tubing to heat and moisture. Pex B underfloor heating pipe is recommended for hydronic radiant panel heating systems utilizing water or an antifreeze solution as the heat transfer media.

Tubing may be installed in concrete, gypsum based lightweight concrete, sand and in or under wood flooring or behind wallboard or plaster. Cross-linked polyethylene, as a material for distributing hot water up to 95°C, has been used worldwide for almost 40 years and has become the best-proven and the most widely used plastic for commercial and domestic installations of underfloor heating. eco hometec cross-linked polyethylene features a specific stabilization process that provides a higher resistance to various phenomena, such as the effects of copper ions, UV-radiation and chlorine in hot water systems.

The piping is certified according to ISO, ASTM and CSA standards, incorporates and oxygen diffusion barrier and complies with DIN 4726 and all European standards for Underfloor Heating Pipe.
