Verdict in brief
The T-M32 and T-M50-N are Takagi's commercial tankless water heaters: the T-M32 fires 24,000 to 240,000 BTU/h with 82.2% NG efficiency and 9.0 GPM in a 56 lb, 4"-flue chassis; the T-M50-N fires 15,000 to 380,000 BTU/h with 80% efficiency and 14.5 GPM in a 113 lb chassis with 5" venting and 1" NPT connections.

The T-M32 and T-M50-N are both heavy-duty commercial tankless water heaters built for multi-unit systems, and neither is a boiler. The T-M32 fires 24,000 to 240,000 BTU/h with 82.2% thermal efficiency on natural gas (83.9% on propane) and 0.5–9.0 GPM, while the T-M50-N fires 15,000 to 380,000 BTU/h at 80% (82% on propane) and 0.5–14.5 GPM.
The physical packages scale with capacity: the T-M32 measures 23.6 × 18.5 × 8.9 in and weighs 56 lb with a 4" Category III flue and 3/4" NPT connections, while the T-M50-N measures 25-1/4 × 24-7/8 × 12-3/4 in and weighs 113 lb with a 5" flue and 1" NPT water/gas connections. Both use 120 V power and share the same 50 ft maximum vent run with 5 elbows.
Manifold capability differs at the top end: the T-M32's sheet supports Easy-Link up to 4 and Multi-Link up to 10 units with the TM-MC01 controller, and the T-M50 sheet prints the same Easy-Link/Multi-Link structure for its higher-capacity systems. The T-M32 page is not live today (spec sheet only), while the T-M50-N and T-M50-P pages are live.
Takagi
The Takagi T-M32 is a non-condensing tankless water heater — a DHW-only appliance, not a boiler — firing 24,000 to 240,000 BTU/h on natural gas or propane with 82.2% thermal efficiency and up to 9 GPM.
Takagi
The Takagi T-M50-N is a non-condensing tankless water heater — a DHW-only appliance, not a boiler — firing 15,000 to 380,000 BTU/h on natural gas with 80% thermal efficiency and up to 14.5 GPM.
Capacity and size: 240,000 against 380,000 BTU/h maximum input, 9.0 against 14.5 GPM, 56 against 113 lb, and 4" versus 5" venting with 3/4" versus 1" water/gas connections.
No. Both are commercial tankless water heaters for domestic hot water; Takagi's catalogue contains no boiler line.
The T-M50-N and T-M50-P product pages are live on takagi.com. The T-M32 product page returns 404 today; it is documented from the live official specification sheet and the support spec-sheets page that lists it as current.
A consultation includes a heat-loss review so the size is right the first time.
