This beast Takagi tankless water heater will heat water from here to eternity.
The T-M50 Series heaters were designed especially for heavy-duty applications. These are the largest Takagi tankless heaters made, and also the most powerful single unit, gas fired tankless heater that exists. Nothing exists that is close to or larger in size.
With gas utilization of up to 380,000 BTU, the T-M50 can produce enough hot water for six bathrooms in warmer climates. With that level of heating capacity, they are also perfect for heavy-duty commercial applications.
The T-M50 Series is often used for commercial locations such as hotels, restaurants, government, convalescent homes, and more. These applications all need high demand and the most durable heaters. The T-M50 Series meets those requirements in two ways:
→ The only commercial units that offer a dual-combustion, dual heat exchanger system, which provides redundancy and reliability, and gives extra assurance that the T-M50 Series heater will remain operational.
→ The heat exchangers use HRS35 copper alloy which is much more heat resistant and durable than standard or lower-grade copper
→ Thicker heat exchanger drum
→ Includes an internal pump control port.
The Takagi T-M50 Series is also ideal for domestic hot water systems (directly or indirectly) with storage tanks, hydronic heating systems, recirculation systems and radiant floor systems.
T-M50 heaters are fully modulating, gas fired, tankless water heaters.
NSF certified for commercial applications
Both ASME and non-ASME versions are available. (Both versions are nearly identical, but the ASME version has been through its certification process.)
Safety features include freeze protection, overheat protection, surge protection, and troubleshooting diagnostic codes display.
