Our take on the Rinnai Trw02cxin 2 Unit Tankless Water Heating System

The Rinnai TRW02CXIN is a factory-built rack that pairs two commercial condensing tankless heaters on one wall-hung frame. It delivers up to 11.6 GPM and 398,000 BTU combined, with a 0.98 Uniform Energy Factor, ultra-low NOx emissions and a 185°F maximum setpoint. It is built for restaurants, salons, laundries and multi-unit buildings that need continuous hot water and redundancy, not for a single-family bathroom. Against field-assembled racks from Navien or Noritz, it arrives pre-plumbed and pre-wired, which cuts install labor but locks you into Rinnai service and parts.

Best forCommercial kitchens and laundries with steady hot-water demandSalons, gyms and car washes needing high flowBuildings that want built-in redundancy from two unitsHigh-altitude installations
Pros
  • Two heaters on one rack give backup if one unit goes down
  • High combined flow for its footprint
  • Condensing design with a 0.98 UEF
  • Ultra-low NOx for strict air-quality rules
  • Pre-assembled rack saves field piping and wiring time
  • Digital display and Wi-Fi monitoring
Cons
  • Heavy at 170 lb; needs solid wall support and two people
  • Commercial-grade unit, so it is overkill for a single home
  • Requires gas, venting and electrical work by a licensed installer
  • Concentric venting limits where it can be placed
  • Service and parts come through Rinnai commercial channels

Questions and answers

Is this system meant for a house?
No. It is a commercial rack rated for high demand and a 185°F setpoint. A single-family home is better served by one residential condensing unit.
How much hot water can it deliver?
Up to 11.6 GPM combined at 398,000 BTU. Actual flow depends on incoming water temperature and the temperature rise you set.
Does it work at high altitude?
Yes, it is a high-altitude model. The installer still needs to set it for your elevation during commissioning.
Can I monitor it remotely?
Yes, it has Wi-Fi compatibility and a digital display. Remote monitoring depends on the Rinnai control accessories and app setup.
What fuel does it use?
It runs on natural gas or liquid propane, with electric ignition. Gas supply sizing must match the combined 398,000 BTU input.
What venting does it need?
It uses concentric venting, so plan the flue route before mounting. The rack weighs 170 lb and needs a reinforced wall.
