Takagi T-M199-NG/LP

 Purchaser Must Specify Natural or Propane Gas

The T-M199 fills a niche between the T-K3 and its big brother the T-M1.

Parallel Installation: Like the T-M1, the T-M199 can be installed in parallel with up to 20 units per controller, for a total of 108 GPM at 60ºF ∆T, or 130 GPM at a 50ºF ∆T. This large flow capacity through parallel connections will meet the hot water needs of all high-volume residential and commercial applications.

Direct-Vent Conversion: The T-M199 can be converted to a direct vent model for inside installation that needs to import combustion air from the outside.

Four Temperature Settings: The T-M199 offers four separate temperatures, set by dipswitch: 113ºF , 122ºF, 140ºF, and 182ºF. Setting temperatures other than these four presets requires the TM-RE10 temperature controller.

At 199,000 BTU/h, the T-M199 offers outputs similar to the T-K3, but its maximum flow rate is higher at the lower ∆T range.

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 5.4 GPM, or 324 GPH.

In colder areas where the input temperature may be 40ºF or less, expect a flow rate about 4.1 GPM, or 246 GPH.
