NETZERO Ultra | TDX3720

The Deep-Pocket Elite — Maximum Recovery for Custom NetZero Estates

The NETZERO Ultra (TDX3720) is the undisputed apex of drain water heat recovery (DWHR) engineering. Crafted exclusively for custom luxury estates, cutting-edge Net Zero architecture, and ultra-high-performance building designs, this flagship model represents the absolute maximum thermal yield possible. When a project demands the best of the best with zero compromise on efficiency, the Ultra is the definitive choice.

By deploying an extended, ultra-high-density thermal exchange profile, the NETZERO Ultra captures an astounding 57.27% of otherwise wasted greywater energy at full standard flow, scaling all the way up to 64.58% for high-efficiency fixtures. Operating 100% passively, it delivers peerless energy savings with zero moving parts, zero electricity, and an entirely maintenance-free operational life.

Intertek Verified Performance Data

Key Technical Advantages

• The Absolute Apex: Delivers an elite 57.27% baseline efficiency, pushing home energy modeling software (like HERS and PHIUS) to its absolute maximum limit for ultimate point accumulation.

• Maximum BTU Capture: Recovers up to a massive 10.53 kW (35,900 BTU/h) of raw thermal energy, instantly taking the heavy lifting off premium water heating systems during peak shower usage.

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

• Luxury-Flow Hydraulics: Masterfully engineered manifold configuration prevents flow restriction, ensuring full-volume, uninterrupted delivery to multi-head luxury showers and spa systems.

• Heirloom Mechanical Build: Weighing 25.66 lbs (11.64 kg) of heavy-duty, high-purity copper, this unit is built to match or outlast the foundations of the estate itself (50+ year lifespan).

Ideal Applications

• Custom Luxury Estates: The ideal mechanical room showcase piece for high-end homeowners demanding maximum self-sufficiency and low carbon footprints.

• Passive House & Zero-Carbon Certifications: A critical component for architects aiming for the highest international standards of green building verification.

"For projects where 'good enough' isn't an option, the NETZERO Ultra stands alone. It represents the pinnacle of passive thermal engineering, converting waste into pure, luxury-grade energy efficiency."
