Buying Guide
- Barrier considerations: Oxygen barrier (EVOH) reduces oxygen diffusion, protecting metal components in heating systems. If your project involves metal manifolds or boilers, prioritize barrier types to extend system life.
- PEX type and flexibility: PEX-A generally offers the greatest flexibility and tightest bend radii, which reduces fittings but can be pricier. PEX-B and non-barrier options may be adequate for simple hot water runs but require more fittings in complex layouts.
- Temperature and pressure ratings: Check maximum operating temperatures (often 180–200°F) and pressure ratings at design temperatures. Higher temperatures may require oxygen barrier or PEX-A variants.
- Installation method compatibility: Ensure tubing is compatible with your fittings (crimp, clamp, expansion, push-to-connect). Some brands emphasize universal compatibility with common fittings, reducing inventory needs.
- Length and run planning: For long runs, consider tubing with strong kink resistance and smooth inner walls to maintain flow and minimize pressure drop. Plan for expansion/contraction in fluctuating climates.
- Certifications and standards: Look for ANSI, ASTM, CSA CAN standards, and NSF certification where applicable. These indicate reliability and compatibility with building codes.
- Color coding and identification: Color can help distinguish cold vs. hot lines and barrier types. Ensure consistent color usage in your project for maintenance clarity.
- Warranty and manufacturer support: A longer warranty and accessible technical support can be valuable for homeowners and contractors undertaking complex radiant heating or multi-zone systems.
