SEAI Grants Available
NEWS - AVAILABLE GRANTS SEAI !!! New funding ranges from €2,700 to €162,600 to support an even wider range of businesses to switch to solar. This will typically support 20-30% of the investment cost, reducing payback to as little as 2 years. New Solar PV Scheme enhancements will boost business investment in renewable energy generation.   SPECIAL EVENTS - SEPTEMBER 14th Association of Energy Engineers Ireland Conference 2023 – at the SETU Arena, Waterford.

What is Pex Pipe?

PEX (cross-linked polyethylene) pipe is a type of flexible tubing used for various plumbing, heating, and cooling applications. It has become popular due to its flexibility, ease of installation, and resistance to freezing and corrosion. It is commonly used for water supply lines, radiant heating systems, and hydronic heating systems.

Advantages of Pex Pipe:

  1. Flexibility:

    PEX pipe is highly flexible and can be bent around corners and obstacles without the need for many fittings, reducing the risk of leaks.

  2. Corrosion Resistance:

    Offer resistant to corrosion, which prolongs the lifespan of the pipe and reduces the risk of rust or mineral buildup that can occur in metal pipes.

  3. Freeze Resistance:

    It is resistant to freezing than traditional metal pipes. It can expand slightly without bursting, making it a good choice for cold climates.

  4. Reduced Noise and Water Hammer:

    Tend to reduce water hammer and noise compared to metal pipes, which can be especially beneficial for plumbing systems.

  5. Cost and Time Savings:

    Often faster to install than traditional pipes due to its flexibility and the use of fewer fittings. This can translate to lower labor costs.

  6. Less Heat Loss:

    PEX's insulating properties result in less heat loss in hot water supply lines, contributing to energy efficiency.

Types of PEX Pipe

Types of PEX Pipe: There are three main types of PEX pipe, each color-coded for identification purposes:

  1. PEX-A (Engel Method): Cross-linking is done through a chemical method known as the Engel method. PEX-A is the most flexible type and is less prone to stress fractures. It can be repaired more easily if it gets kinked.
  2. PEX-B (Silane Method): Cross-linking is achieved by exposing the PEX material to electron beams. PEX-B is less flexible than PEX-A but still suitable for most plumbing applications.
  3. PEX-C (Irradiation Method): Cross-linking is done through a high-energy electron method. PEX-C is stiffer than PEX-A and PEX-B but maintains its shape well when bent.

PEX Fittings: PEX piping uses specific fittings, often made from brass or other compatible materials. Common types of fittings include crimp, clamp (also known as cinch), and push-fit fittings. These fittings create secure connections between PEX pipes and are designed to withstand pressure and temperature variations.

Applications of PEX Pipe:

  1. Potable Water Supply: PEX is used for cold and hot water supply lines in residential and commercial buildings.
  2. Radiant Heating Systems: PEX tubing is used in hydronic radiant floor heating systems to circulate warm water through the floor, providing efficient and even heat distribution.
  3. Plumbing Systems: PEX is commonly used for plumbing systems, replacing traditional copper or PVC pipes in many cases.
  4. Snow and Ice Melting Systems: PEX tubing can be used in outdoor systems to melt snow and ice on driveways, walkways, and roofs.
  5. Chilled Water Systems: PEX can also be used for circulating chilled water in cooling systems.

Installation Considerations:

    • Proper tools, such as crimping or cinching tools, are necessary for secure connections.
    • PEX should be protected from direct sunlight and UV exposure, which can degrade the material over time.
    • Local building codes and regulations should be followed during installation.
    • Proper insulation is important in hydronic heating systems to prevent heat loss.
