Takagi T-M1-NG/LP, Tankless Hot Water Heater

 Purchaser Must Specify Natural or Propane Gas

At 235,000 BTU per hour, the Mobius T-M1 is Takagi's largest model, with an average efficiency of 82% with natural gas and 85% with propane. At a ∆T of 60ºF in warmer areas - for example, where the winter ground water is 60ºF and with the output set at 122ºF - the unit will provide a 6.4 GPM, or 384 GPH.

In colder areas where the input temperature may be 40ºF or less, expect a flow rate about 4.5 GPM, or 270 GPH.

The T-M1 can provide at least three showers' worth of water simultaneously along with one appliance at input temperatures of 60ºF or greater.

The venting system for this unit is not convertible to direct vent and requires that makeup air be provided. Please refer to "Accessories" for more information on venting options.

Mobius T-M1 units can be combined to offer a fully modulating, boiler-type system. Up to 20 units may be installed in parallel, using the TM-RE20 multi-unit controller and the TM-RE10 temperature controller. All heaters up to 20 units will fully modulate, from as low as .75 GPM, or 25,000 BTU per hour; to as high as 128 GPM, or 4.7 million BTU per hour at 60ºF ∆T.

In terms of boiler language, each modulate has a turndown ratio of 9.4:1. As a result, combining 20 units equates to a 188:1 turndown ratio - a tremendous savings compared with an average boiler. This very powerful system is ideal for sports clubs, hotels, apartment buildings, hospitals, etc. where hot-water volumes are high and flows are variable.

The Mobius T-M1 is built to last in even the most rugged on environments, whether installed inside or outdoors. Like all of Takagi's heaters, the unit features all copper and brass waterways, stainless steel burners and epoxy-powder coatings to resist rust and corrosion. Yet the high compact Mobius weighs in at a trim 70 pounds and occupies only a little more than two cubic feet of space. In short, the T-M1 packs a powerful punch in a comparatively small package.

The four preset temperatures on the unit are: 113ºF , 122ºF, 140ºF, and 182ºF. To achieve any temperatures other than those presets, the user will require the TK-RE10 temperature controller. This controller is optional on a single T-M1 installation and required on multiple installations.
