TDX Builder Pro | TDX3350

The Ontario Standard — Targeted at SB-12 and Tier 3 Compliance

The TDX Builder Pro (TDX3350) is the strategic choice for high-volume residential developers navigating strict modern building codes. Specifically engineered to hit the critical efficiency baselines required by Ontario's SB-12 amendments and upper-tier building frameworks, this model represents the perfect intersection of performance, length, and cost. It is the premier "go-to" mechanical upgrade for production builders looking to clear compliance hurdles seamlessly.

By deploying an optimized 35-inch vertical profile, the TDX Builder Pro hits a verified 42.07% efficiency at standard flow, giving energy advisors exactly what they need to model compliance without forcing builders into massive, oversized units. Operating 100% passively, it features zero moving parts, zero electricity requirements, and zero ongoing maintenance.

Key Technical Advantages

• The Compliance Sweet Spot: Precision-engineered to surpass the 42% benchmark, making it the most cost-effective way to secure SB-12 path approvals and Tier 3 energy incentives.

• Optimized 35" Footprint: Designed to fit comfortably within standard residential plumbing drops and standard floor-joist configurations while maximizing active thermal transfer.

• Dual-Wall Safety Integration: Features a fully certified double-wall separation barrier with a vented leak path, ensuring 100% security for the potable water supply.

• High-Velocity Hydraulics: Advanced manifold engineering maintains ultra-low pressure drop across the unit, protecting delivery volumes to main-floor showers and upper baths alike.

• Mid-Weight Agility: Weighing in at a highly manageable 13.07 lbs (5.93 kg), this model ensures quick, ergonomic handling and fast single-person installation on busy jobsites.

• Lifetime Material Integrity: Built from premium, high-conductivity copper that delivers up to 30 to 50 years of continuous, passive thermal recycling.

Ideal Applications

• Production Home Subdivisions: The most strategic choice for mass-scale residential framing where hitting specific energy performance tiers dictates municipal sign-offs.

• Energy-Framed Retrofits: A highly versatile replacement or upgrade component that easily slides into existing standard 3-inch plumbing stacks.

"When building codes demand verifiable performance metrics and budgets require strict cost-containment, the TDX Builder Pro is the ultimate solution. It is the definitive code-compliance standard for production homebuilding."
