<p>The T-M50 supplies hot water to domestic hot water systems (directly or indirectly) which can be used with storage tanks, recirculation systems, hydronic heating systems, radiant floor systems, and/or domestic & heating applications. <br />The T-M50 is a fully modulating, gas fired, tankless water heater perfect for commercial applications. With gas inputs of 380,000 BTU, the T-M50 can produce enough hot water for six bathrooms in warmer climates. An ASME version is also available. <br />Thicker heat exchanger drum and utilizes HRS35 (heat-resistant) copper for the heat exchanger tubing. Incorporates a dual system for redundancy, providing added assurance that the T-M50 Series will remain operational. Includes an internal pump control port. Easy- Link System capable up to 4 units. Multi-Unit System capable up to 10 units. </p><p><b>Features:</b></p> <ul> <li>15-year limited heat exchanger, 5 yrs limited parts Residential use</li> <li>10-year limited heat exchanger, 5 yrs limited parts Commercial use</li> <li>Thermal Efficiency of 80.4% for Liquid Propane</li> <li>Maximum flow rate of 14.5 GPM at 35°F temperature rise (8.7 GPM at 70°F rise)</li> <li>Heat exchanger utilizes HRS35 commercial-grade copper alloy</li> <li>NSF certified for commercial applications</li> <li>Internal pump control port</li> <li>Easy-Link up to four units without a Multi-Unit Controller</li> <li>Multi-Link up to 10 units with a Multi-Unit Controller</li> <li>Venting with Category III stainless steel</li> <li>Safety features include freeze, overheat, surge protection, and troubleshooting diagnostic codes</li> </ul> <p>The T-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!</p>
