Code Compliance, Performance Standards & Material Specifications
North American Energy Code Compliance
• Ontario Building Code (OBC SB-12): Fully compliant with mandatory prescriptive paths requiring a minimum 42% rated efficiency per CSA B55.1.
• National Building Code of Canada (NBC 9.36): Serves as a vital compliance pathway for achieving Tier 3 through Tier 5 energy performance targets.
• US IECC & ASHRAE 90.1 / 189.1: Recognized compliance measure for commercial and multi-family building energy efficiency mandates.
• California Title 24: Registered with the California Energy Commission (CEC) as an approved compliance option for residential and commercial domestic hot water heating.
Safety, Plumbing & Performance Certifications
• Double-Wall Potable Safety (CSA B55.2): Vented double-wall copper and alloy construction provides a fail-safe physical barrier with an external leak-detection path, preventing cross-contamination between drain wastewater and drinking water.
• Efficiency Verification (CSA B55.1 & IAPMO IGC 346): Third-party tested and verified by Intertek for heat recovery efficiency and minimal pressure drop.
• Model Plumbing Code Approved: Fully compliant with the International Plumbing Code (IPC), Uniform Plumbing Code (UPC), and National Plumbing Code of Canada (NPC).
ThermoDrain TDX Series & Material Specifications
• TDX SS316 Heavy-Duty Outer Shell: Features a marine-grade Stainless Steel 316 outer shell paired with a high-conductivity copper interior core, delivering maximum structural durability and high heat-density recovery in low-clearance or harsh installation spaces.
• Enhanced Corrosion Protection: Stainless Steel 316 grade shielding provides superior resistance to aggressive water chemistries, chlorides, and environmental exposure in commercial and residential retrofits.
• Potable Water Tubing & Core Pipe: Heavy-gauge, seamless ASTM B88 copper inner tubing and ASTM B306 DWV copper drain piping.
• Fittings & Flexible Layouts: ASME / ANSI B16.18 and B16.22 compliant connections. Certified for Equal Flow (split feed to heater and fixtures), Water Heater Feed Only, or Shower Feed Only configurations.
Green Building Ratings & Decarbonization
• LEED v4 / v4.1 Certification: Earns valuable points under Energy & Atmosphere (EA) credit categories for optimizing energy performance.
• HERS & ERI Index Scores: Substantially lowers HERS (Home Energy Rating System) scores and ERI points in energy modeling for multi-family and residential builds.
• Decarbonization & Net-Zero: Directly reduces peak electric and gas domestic hot water demand, helping new developments hit Net-Zero Energy (NZE) goals.
