Welcome to Plumbers Sherman TX. In this blog post, we are going to discuss how to install PEX tubing for baseboard heat. Let’s jump into the main topic. Keep in mind to read the whole content to know everything.

When it comes to heating your home efficiently, baseboard heaters are a popular choice. To enhance the performance and ease of installation, many homeowners are turning to PEX tubing. In this guide, we will explore the ins and outs of using PEX for baseboard heating and provide step-by-step instructions on how to install it effectively.

How to Install PEX Tubing for Baseboard Heat

Baseboard heaters have long been associated with traditional copper piping, but PEX tubing offers a more convenient and cost-effective alternative. Here’s a comprehensive guide on installing PEX tubing for baseboard heat.

Factors to Consider When Using PEX for Baseboard Heating

Before diving into the installation process, it’s crucial to understand certain factors that can affect the efficiency of PEX tubing in a baseboard heating system.

  1. Low Expansion Capacity: PEX has a low expansion capacity in low temperatures. Avoid placing it in colder areas to prevent potential issues.
  2. Boiler Temperature: Ensure your boiler produces adequate heat, preferably around 180 degrees, to maintain an average temperature of 160 degrees in the PEX tubing.
  3. Loop Configuration: Maintain a single loop throughout your home or building for even heat distribution.

Why Should I Use PEX For Baseboard Heat?

PEX tubing presents several advantages that make it an ideal choice for baseboard heating:

  • Corrosion Resistance: PEX is resistant to corrosion and mold development, enhancing the safety and longevity of your heating system.
  • Flexibility: PEX’s flexibility makes it easy to install in hard-to-reach areas, simplifying the installation process.
  • Cost-Effective: PEX is more affordable than copper, reducing overall project costs. Its easy installation also saves time and effort.

Drawbacks of Using PEX Pipe for Baseboard Heat

While PEX tubing has many advantages, it’s essential to be aware of its drawbacks:

  • Vulnerability to UV Damage: PEX is sensitive to UV damage, so it should be protected from direct sunlight during installation.
  • Limited Tensile Strength: PEX lacks sufficient tensile strength, meaning it may retain a bent shape if accidentally deformed during installation.

Are There Issues That Can Arise from Using PEX for Baseboard Heating?

Connecting PEX with a baseboard heater is not without its challenges. PEX tends to expand and may come out of the baseboard enclosure when temperatures rise. To mitigate this, ensure the PEX temperature rating matches that of the baseboard heater and use zip ties to secure it in place.

For installations in colder areas, consider PAP (PEX-AL-PEX), a five-layer pipe with aluminum, adhesive, and plastic, offering lower expansion coefficients suitable for such conditions.

Where Can I Get PEX For Baseboard Heaters?

PEX tubing is readily available from various retailers, both online and in local stores. Ensure you purchase the correct type and size for your baseboard heating system.

What Type of PEX Should One Use for Baseboard Heat?

When selecting PEX for baseboard heat, opt for the red-colored variant, as it is designed to transport hot water. Familiarize yourself with other PEX colors, each serving specific purposes, such as blue for cold water and white or gray for both hot and cold water.

Does Size Matter When Using PEX For Baseboard Heaters?

Size is a critical factor when choosing PEX for baseboard heaters. Use PEX with an oxygen barrier to prevent system corrosion. Additionally, carefully select the pipe size and length to ensure proper fitting and distribution of heat.

What Is a Baseboard Heater?

Before delving further into PEX installation, it’s essential to understand what a baseboard heater is and how it functions.

A baseboard heater is a zone heating device located at the bottom of a wall, providing independent temperature regulation for each room. It operates without the need for a furnace or heating duct, making it a cost-effective and easy-to-install heating solution.

Why Should You Consider PEX Over Other Pipes for Baseboard Heaters?

PEX tubing revolutionized the plumbing and heating industry by offering a superior alternative to traditional materials. Compared to copper and PVC, PEX is more flexible, cost-effective, and easier to install. Builders and homeowners alike have embraced PEX for its efficiency and durability.

Tips for Installing PEX Tubing for Baseboard Heat

Now that we’ve covered the basics, here are some tips for a successful PEX tubing installation for baseboard heating:

  1. Secure Properly: Use zip ties or brackets to secure the PEX tubing to the baseboard to prevent movement during temperature fluctuations.
  2. Consider PAP for Colder Areas: In regions with colder temperatures, opt for PAP (PEX-AL-PEX) for its lower expansion coefficient.
  3. Use Expansion Couplers: Install expansion couplers on long runs to accommodate PEX tubing expansion and prevent issues with movement.
  4. Maintain Temperature Rating: Ensure the PEX temperature rating aligns with that of the baseboard heater to prevent expansion-related problems.
  5. Insulate PEX Where Necessary: In areas prone to noise or expansion concerns, consider insulating the PEX tubing using foam pipe insulation or wire loom to isolate movement and prevent squeaking.
