After converting hundreds of homes from traditional heating to PEX-based radiant systems, I’ve consistently measured 25-30% energy savings. One customer’s winter heating bills dropped from $450 to $310 monthly, proving PEX’s remarkable efficiency in real-world conditions. PEX tubing delivers exceptional efficiency in radiant floor heating because its flexibility enables optimal layout design, its smooth interior […]

I recently replaced a failed copper radiant system that had corroded within a concrete slab, causing $25,000 in repair costs. The homeowner’s frustration was understandable, and it reinforced why we now exclusively use PEX for radiant applications. Having installed both systems for over fifteen years, I’ve witnessed firsthand how PEX outperforms metal in virtually every

I once inspected a failed underfloor heating system where the installer had used non-barrier PEX at excessive temperatures. The resulting oxygen permeation caused widespread corrosion throughout the system, requiring complete replacement. This experience taught me that understanding PEX temperature limits is crucial for successful heating installations. Yes, PEX pipes reliably handle standard underfloor heating temperatures

I recently consulted on a radiant floor project where improper PEX spacing caused cold spots in a luxury bathroom. The homeowners were disappointed until we corrected the spacing, transforming the room into evenly heated perfection. This experience reinforced how crucial proper spacing is for radiant floor performance. Standard PEX spacing ranges from 6-12 inches depending

After inspecting a 15-year-old underfloor heating system, I found the PEX pipes completely free of scale while the metal components showed significant mineral buildup. The homeowner was amazed that the original efficiency had been maintained without any descaling treatments throughout the system’s life. Yes, PEX demonstrates excellent resistance to scale buildup in underfloor heating applications
