T-M50 Takagi Tankless Water Heater (Natural Gas)

The Takagi brand has been discontinued by the manufacturer as of December 31, 2025. Suggested replacement units will be available on our website and replacement parts will continue to be available as supplies last. If you'd like any further assistance, please contact our customer service team.

This water heater has a heat input of greater than 200,000 BTU's and is governed by Section IV (HLW) of the Pressure Vessel Codes prepared by ASME Criteria. Check your local code requirements to confirm if a Non ASME water heater is allowed in your area.

Rebate
Think Green, Save Green. Rebate and incentive programs provide cash-back to consumers for the purchase of appliances that meet certain energy efficiency standards. Most states are offering rebates in the $50 to $250 range. You can search for rebates in your area from here.

The New T-M50 model, also known as "The Monster Tankless," is Takagi's most powerful tankless water heater yet and was developed specifically for heavy duty commercial applications. The T-M50 offers "true commercial grade" components and can be Easy-Linked and Multi-Linked to meet high demands. The T-M50 also offers a dual-combustion system for added redundancy.

Note: Isolation valves are not included but are recommended for installation.

Features:

• This unit is NOT approved for installation in Manufacture Homes and is not suitable for space heating applications only.
• 380,000 BTU/U, up to 14.5 GPM (Max)
• The versatility of being installed either indoor, outdoor, or with a direct vent, all with the same unit.
• Easy-link capability up to 4 units. You may connect up to 10 units and generate over 140 GPM using a multi-controller unit.
• Features a Dual-Heat Exchanger system that allows for redundancy. In the event of an emergency, if one system goes down, the other system will still stay running.
• Uses HRS copper, the most durable copper in the industry. HRS copper is stronger and harder than the standard copper, making it much more resilient against erosion and leaks.
• Offers precise control of the water valves.
• 8 new dipswitch temperature settings: 100 F, 115 F, 120 F, 135 F, 145 F, 155 F, 165 F, and 185 F. These temperatures are better suited for commercial applications.
• 7-segment LED for error codes: Remote controller is not required to pinpoint problems.
• Ignition indicators: indicates which burner is fired up at the moment.
• Utilizes the air-fuel ratio rod for added safety.
• The drum thickness has been increased 25% for greater heat exchanger performance and to be more resistant to thermal stress.
• Increase in fin pitch: Fins are more "spread out" which improves the durability of the heat exchanger. More space in-between the fins reduces build-up. Higher temperatures at the top of heat exchanger reduces condensation.
