How to Upsell ThermoDrain on Every Water Heater or Remodel Job

+$300 to $600 Profit Per Rough-In or Changeout

When customers call because their water heater is dying or their family is running out of hot water during morning showers, upsizing the tank often requires larger gas lines, heavier venting, or expensive 200A electrical panel upgrades. ThermoDrain solves the client's problem on the spot while doubling your ticket size:

The 30-Second Customer Script:

"While we have your system drained down today, we can cut a ThermoDrain into your main basement stack. It preheats your cold groundwater using waste shower heat, effectively doubling your hot water capacity and cutting your water heating bill by 30% to 40%. It has no moving parts, requires zero maintenance, and will outlast two water heaters."

Tankless Applications

Eliminates cold-water temperature drop in winter, preventing tankless flow-rate throttling.

Heat Pump Water Heaters

Reduces strain on the compressor and drastically reduces the need for backup electric resistance elements.

Standard Storage Tanks

Doubles effective first-hour shower output without replacing the existing 40- or 50-gallon tank.

Engineered for the Field: Fast 45-Minute Rough-In

Designed by tradespeople for tradespeople. No specialized tooling, no complex programming, and zero commissioning callbacks.

Drain Side

1. Standard Mechanical Couplings

Cut out a section of the existing 3" or 4" ABS, PVC, or cast iron stack. Slip the unit into line and secure it using standard shielded transition couplings (Fernco, Mission, or Proflex).

Potable Side

2. Standard 3/4" PEX Connections

ThermoDrain comes factory-equipped with 3/4" ASTM F1807 crimp, ASTM F1960 cold expansion, or copper sweat connections. Connect directly to your incoming cold supply line with standard fittings.

Plumbing Layout

3. Equal Flow Configuration

Route the preheated output line to feed both the cold inlet of the water heater and the cold port of the primary shower mixing valve for maximum heat transfer efficiency and client satisfaction.

Commissioning

4. Pressurize & Walk Away

Pressure-test potable connections per code. No electrical hookup, no venting, no condensate drains, and zero startup calibration. Collect your payment and move to the next job.

Dual-Metal Engineering: Stainless Steel Armor + Copper Core

The TDX Series features a rigid stainless steel outer protective jacket designed to withstand jobsite handling and rough basement conditions, wrapped around a high-conductivity antimicrobial copper core. It gives your crew a clean, durable product that installs cleanly without fragile exposed tubing.

Plumber Model Sizing & Rough-In Parameters

Match your vertical stack clearance. All models feature minimal pressure drops to preserve full fixture flow.

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 vertical drain stack. It preheats incoming municipal cold water from 40°F–50°F (4°C–10°C) up to 70°F–80°F (21°C–27°C) using your shower waste 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 outlast two water heaters."

Tankless Water Heaters

Eliminates cold-water temperature drop in winter, preventing automatic shower flow-rate throttling.

Heat Pump Water Heaters

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

Standard Storage Tanks (40/60 gal • 150/225 L)

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

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

Designed by tradespeople for professionals. Direct solvent cement connection. Factory PEX fittings. No mechanical couplings, no soldering, and no callbacks.

Solvent Weld

1. Direct Drain Glue-In

The TDX glues directly onto standard 3" (76 mm) vertical ABS or PVC drain stacks using standard solvent cement. No rubber mechanical sleeves, no Fernco bands, and no torque wrenches required.

100% PEX Ready

2. Zero Copper Soldering

Factory-preinstalled 3/4" (19 mm) 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 & Finish

Perform the standard pressure leak test per code. No electrical connections, no exterior vents, no condensate drains, and zero electronic sensors 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 shields the coils against jobsite impacts during rough handling and ensures an immaculate industrial finish.

Rough-In Dimensions & Plumber Model Selection

Select based on available stack height. Direct solvent weld hubs and factory PEX fittings on all TDX models.
