Introduction

In this tutorial, we will explore the strengths and weaknesses of different types of pipes used for heating systems, specifically focusing on cross-linked polyethylene (PEX), polypropylene, and PERT pipes. We will also differentiate between metal-plastic and cross-linked polyethylene pipes. This guide aims to help you make informed choices for heating systems in private homes and includes a brief masterclass on radial and axial press fittings.

Step 1: Understand Pipe Types

Familiarize yourself with the main types of pipes used for heating systems:

• Cross-Linked Polyethylene (PEX)

  • Flexible and resistant to scale and chlorine.
  • Can expand and contract with temperature changes.
  • Excellent for residential heating applications.

• Polypropylene

  • Lightweight and easy to install.
  • Offers good thermal insulation.
  • Suitable for low-temperature heating systems.

• PERT (Polyethylene of Raised Temperature Resistance)

  • Similar to PEX but designed for higher temperature resistance.
  • Good flexibility and can handle pressure well.

Step 2: Compare Metal-Plastic and Cross-Linked Polyethylene

Learn the differences between metal-plastic and cross-linked polyethylene pipes:

• Metal-Plastic Pipes

  • Composed of layers of plastic and metal.
  • Offers good strength and resistance to pressure.
  • Installation requires special fittings.

• Cross-Linked Polyethylene Pipes

  • Made entirely of plastic, making them lightweight.
  • Do not require special fittings and are easier to install.
  • Provide better resistance to corrosion and scaling.

Step 3: Choose the Right Pipe for Your Heating System

Consider the following factors when selecting the best pipe for your heating system:

• Temperature and Pressure Requirements

  • Assess the maximum temperature and pressure your system will experience.

• Flexibility and Installation

  • Choose PEX for curved installations or tight spaces; it’s more flexible than metal-plastic pipes.

• Cost and Availability

  • Compare prices and check local availability of each pipe type to stay within budget.

Step 4: Learn About Press Fittings

Gain knowledge on radial and axial press fittings:

• Radial Press Fittings

  • Designed for easy connection of pipes.
  • Ensure a leak-proof seal when installed correctly.

• Axial Press Fittings

  • Provide a strong connection for larger diameter pipes.
  • Typically used in more industrial or high-pressure applications.

Installation Tips:

• Always ensure pipes are clean and free from debris before fitting.
• Use the appropriate tools for pressing to avoid damaging the fittings.

Conclusion

Choosing the right pipes for your heating system is crucial for efficiency and longevity. Understanding the differences between PEX, polypropylene, and PERT, as well as the distinctions between metal-plastic and cross-linked polyethylene, will help you make an informed decision. Additionally, knowledge of radial and axial press fittings will aid in proper installation.
