Increase Your Margins. 45-Minute Installation. Zero Callbacks.

The ThermoDrain® TDX series drain water heat recovery (DWHR) system has been redesigned specifically for jobsite realities and emergency water heater replacements. Engineered with direct glue (solvent) drain spouts and factory PEX fittings, the TDX installs in minutes with no coupling sleeves and no torch soldering. Add high-margin, profitable equipment to every invoice with zero electricity, zero moving parts, and zero warranty callbacks.

Business Opportunity

How to Monetize Every Water Heater Replacement or Renovation

+$300 to $600 Profit Per installation or replacement

When a customer calls you in an emergency for an end-of-life water heater or because their family continually runs out of hot water in the morning, increasing the tank volume often imposes heavy constraints: breaker replacements, 200A electrical services, or vent modifications. The ThermoDrain TDX solves the problem immediately while boosting your invoice:

The 30-Second Client Pitch:

« While your plumbing is drained today, we can solvent-weld a ThermoDrain TDX directly into your main drain stack. It preheats incoming municipal cold water using your shower heat, giving you 3x more hot water for showering and cutting water heating bills by 30% to 40%. It has no moving parts, requires zero maintenance, and will last longer than two water heaters. »

Tankless Water Heaters

Eliminates cold water temperature drop in winter and prevents automatic shower flow restriction.

Heat Pump Water Heaters

Relieves the compressor and prevents energy-consuming backup electric elements from engaging during peak periods.

Standard Tanks (40/60 gal)

Delivers 3x more hot water for showering without needing to upgrade to a larger tank or modify wiring.

Built for the Jobsite: Fast 45-Minute Solvent Weld Installation

Designed by tradespeople for professionals. Direct solvent glue connection. Factory PEX fittings. No sleeves, no soldering, and no callbacks.

Solvent Weld

1. Direct Drain Glue-In

The TDX glues directly onto standard 3-inch vertical ABS or PVC drain stacks using standard solvent cement. No rubber mechanical sleeves or hose clamps required.

100% PEX Ready

2. No Copper Soldering

Factory-preinstalled 3/4" PEX fittings (ASTM F1807 crimp or ASTM F1960 cold expansion). No open flame, no torch near wood studs, and no soldering on the unit.

Hydraulic Configuration

3. Equal Flow Connection

Route the preheated water output to simultaneously feed the cold water inlet of the water heater and the cold port of the main shower mixing valve for maximum thermal efficiency.

Commissioning

4. Pressure Test & Go

Perform the standard pressure leak test. No electrical connections, no exterior vents, no condensate drains, and no circuit boards to calibrate.

Bimetallic Engineering: Stainless Armor + Pure Copper Core

The TDX series protects its high-conductivity antimicrobial copper heat exchange coils under a rigid exterior stainless steel jacket. This protects the coils against jobsite impacts during rough handling and ensures an immaculate industrial finish.

Rough-In Dimensions & Plumber Selection

Select based on available stack height. Direct glue spouts and factory PEX fittings on all TDX models.
