TDX Builder Pro | TDX3350 42.07% Efficiency

TDX Builder Pro | TDX3350 The Contractor Standard — The Easiest Path to Code Compliance

The TDX Builder Pro (TDX3350) is the ultimate industry standard for high-volume residential home building and major renovations. Measuring a highly versatile 35 inches long, this unit is engineered specifically to clear strict building code thresholds at the absolute lowest installation cost. It is the premier "go-to" specification for high-volume production builders, mechanical contractors, and energy advisors across North America.

By capturing falling-film thermal energy from greywater to pre-heat incoming cold water, the TDX Builder Pro smoothly delivers critical energy-efficiency points to standard builds without breaking the budget. Operating entirely passively, it features zero moving parts, zero electrical requirements, and zero ongoing maintenance.

Intertek Verified Performance Data

• 9.5 LPM / 2.5 GPM Flow Rate: 42.07% Efficiency (7.73 kW / 26,400 BTU/h)

• 7.0 LPM / 1.85 GPM Flow Rate: 46.85% Efficiency (6.18 kW / 21,100 BTU/h)

• 5.5 LPM / 1.45 GPM Flow Rate: 49.33% Efficiency (5.20 kW / 17,736 BTU/h)

Key Technical Advantages

• Direct-Glue ABS Connection: Built with integrated ABS connection hubs, allowing installers to solvent-weld (glue) the unit directly into standard ABS drain stacks using standard cement—completely eliminating the need for separate mechanical couplings.

• Built for Code Compliance: Delivers a verified 42.07% efficiency at standard flow rates, specifically optimized to effortlessly meet or exceed mandatory 42% baseline code targets (such as Ontario SB-12 regulations) at the lowest hardware cost-per-door.

• Self-Scouring Solid Waste Passage: The central core features completely smooth, continuous interior copper walls with zero internal restrictions or baffles. Standard residential solid waste passes through seamlessly with zero clogging risk.

• Factory-Integrated PEX Ports: Features built-in PEX-ready manifold connections, slashing jobsite installation times by eliminating the need for separate copper-to-PEX transition adapters.

• Unmatched ROI Sizing: Provides the perfect economic sweet spot between structural height footprint, equipment cost, and thermal recovery percentage.

• Dual-Wall Safety Integration: Features a fully certified double-wall separation barrier (CSA B55.2) with a vented leak path, ensuring 100% security for the potable water supply.

• Ultra-Low Pressure Drop: The advanced manifold configuration keeps hydraulic resistance minimal, preserving full-volume shower performance even in low-pressure municipal zones.

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

Ideal Applications

• High-Volume Single-Family Subdivisions: The baseline mechanical upgrade of choice for production builders looking to fast-track energy modeling approvals across large residential developments.

• Residential Bathroom Renovations: The ideal drop-in size when stripping walls or framing basements during home layouts, instantly increasing effective hot water delivery up to 3x.

"When your project needs to hit building code margins smoothly and economically, the TDX Builder Pro delivers. It glues directly into the stack, hooks into PEX in seconds, and clears code thresholds at a price point engineered for residential budgets."
