Takagi T-M32 in practice
The T-M32 is the natural gas or propane indoor model in Takagi's T-M32 tankless water heater family. Takagi — Mobius T-M32 Specification Sheet (T-M32 spec sheet) prints an input range of 24,000 to 240,000 BTU/h with 82.2% thermal efficiency (NG; 83.9% on LP), up to 9 GPM maximum flow, 3/4" NPT water connections and a 3/4" NPT gas connection.
The unit measures 23.6 × 18.5 × 8.9 in (H × W × D) and weighs 56 lb, and it is installed indoors. 4" Category III stainless steel to 50 ft, 5 elbows max; optional 4" combustion-air intake. It is a tankless water heater, not a boiler: Takagi's catalogue contains no boiler line, and where the family is used with storage tanks, recirculation or combined domestic & heating applications, the appliance remains a water heater whose installation and system design follow the official manual and local code.
The product page /t-m32-n returns 404 today; the model is documented from the live official specification sheet and the support spec-sheets page, which lists T-M32-IN/OS as current. The sheet prints one T-M32 rating row (Fuel: NG or LP) with separate gas-pressure and efficiency rows per fuel. No Canadian availability statement appears on the captured pages, so Canadian availability is recorded as unknown. Sizing, venting design and gas-supply capacity are engineering decisions for a licensed contractor following the current installation manual.
Best suited to
- Indoor domestic hot-water service at up to 240,000 BTU/h input
- Projects needing 82.2% thermal efficiency (NG; 83.9% on LP) operation with up to 9 GPM
- Commercial loads with multi-unit linking (Easy-Link up to 4; Multi-Link up to 10 with controller)
