T-M50-N
Specifications
The M50 Series, specifically designed for heavy-duty applications, is the largest
Takagi tankless heater yet and the most powerful (14.5 GPM max) in the tankless industry.
The M50 Series is suitable for commercial applications (hotels, restaurants, government,
convalescent homes, etc.) that require high demand and the most durable of heaters. Along
with commercial-grade copper alloy, the M50 Series is the only commercial unit in the industry
that offers a “dual-combustion system,” providing redundancy for added reliability.
