Drain water heat recovery High-Density Thermal Exchange: Engineered to outperform standard units by maximizing heat transfer surface area within a compact 2-foot vertical span. Integrated PEX Manifold: Factory-installed PEX ports eliminate the need for copper-to-PEX adapters, reducing parts-count and labor time. Certified Dual-Wall Construction: Provides a redundant safety barrier between greywater and potable water, meeting the strictest North American plumbing codes. Low-Profile Form Factor: Ideal for 24" joist spaces, crawlspaces, and low-ceiling mechanical rooms where traditional 60" units cannot be installed. Zero-Maintenance Passive System: No moving parts, no electricity, and no pumps. Provides silent, reliable energy savings for 30+ years. High-Flow Hydraulics: Manifold design ensures ultra-low pressure drop, maintaining full-volume performance for luxury showerheads.

Product Metafields: Additional Information (TDX3240-PEX)1. Compliance & CertificationPotable Water Safety: Certified Dual-Wall construction with a vented leak path. Meets or exceeds all North American plumbing codes for double-separation between greywater and potable water.Testing Standard: Performance verified under CSA P.3-15 (Steady-State Efficiency Testing) at a flow rate of 9.5 LPM (2.5 GPM).Material Grade: Constructed using high-conductivity, antimicrobial Type L/M Copper, ensuring 50+ years of corrosion resistance.2. Installation & CompatibilityMounting Requirement: Must be installed in a vertical orientation to ensure a "falling film" effect for maximum heat transfer.Plumbing Integration: Features integrated PEX-ready manifold ports. Compatible with all standard PEX-a (Expansion) and PEX-b (Crimp) systems.Drain Connection: Designed for standard 3-inch (76mm) copper DWV stacks. Can be adapted to PVC or ABS stacks using shielded transition couplings (sold separately).3. Maintenance & LongevityService Life: 30–50 years (matching the lifespan of the building's plumbing).Maintenance Profile: Zero maintenance required. The passive design has no moving parts, no filters to clean, and no electrical components to fail.Self-Cleaning: The high-velocity vertical flow design is naturally self-scouring, preventing the buildup of biofilm or sediment.4. Trade & Shipping Data Country of Origin: Made in Canada (London/Toronto region).Trade Status: CUSMA/USMCA Qualified. Eligible for 0% duty for export to the USA and Mexico.HS Code: 8419.50.00.00 (Heat Exchange Units).Sustainability: 100% Recyclable at end-of-life. Contributes to LEED points and NGBS (National Green Building Standard) certification.5. Technical Performance Notes Pressure Drop: Ultra-low hydraulic resistance (<2.0 psi at 9.5 LPM). Will not impact the performance of multi-head luxury showers or high-flow fixtures.Thermal Expansion: Designed with a manifold architecture that accommodates thermal expansion and contraction without stressing the primary drain stack.
