NTI Trin & Stor Stainless Steel Indirect Water Heater – Installation Included

The NTI Trin & Stor indirect water heater is a premium stainless steel hot water storage tank designed to work with high-efficiency boilers. Installed by Bison Air across Toronto and York Region, it provides fast recovery, long lifespan, and reliable hot water for hydronic heating homes.

Unlike standalone water heaters, an indirect tank uses your boiler’s heat output to deliver higher hot water volume and efficiency.

  • Passivated stainless steel tank

  • Stainless steel heat exchanger coil

  • Corrosion-resistant design

Faster Hot Water Recovery with Boiler Power

Indirect tanks recover significantly faster than conventional water heaters because they use the full output of your boiler.

Typical benefits:

  • Higher first-hour hot water delivery

  • Ideal for radiant + domestic hot water systems

  • Consistent temperature stability


S20W Wall-Mounted High-Performance Model

  1. Delivery of the Boiler
    Your new boiler will be safely delivered to your home.

  2. Removal of Existing Equipment
    We will disconnect and remove your old boiler if necessary.

  3. Connecting the New Boiler

    • Installation of the new boiler in the same location as the previous one.
    • Connection to existing plumbing, gas, and electrical lines.
    • Integration with the existing heating system, including radiators or baseboard heaters.
  4. Standard Venting
    Includes installation of a flue system for proper ventilation, adhering to safety codes.

  5. System Testing
    Comprehensive testing of the boiler to ensure it operates safely and efficiently.

  6. Basic Cleanup
    Disposal of the old boiler and materials, leaving your space tidy.


Additional Costs May Apply for Non-Standard Installation

Some situations may require work beyond standard installation. Examples include:

  • Moving the boiler to a different location.
  • Upgrading electrical or plumbing systems.
  • Installing a complex or high-efficiency venting system.
  • Adding a condensate pump or other accessories.

Please note that the boiler cannot be sold without installation, as it requires a certified technician to carry out the installation for safety reasons.
