The flow rate and capacity of tankless water heaters depends on the temperature difference between the desired output and the incoming water temperatures. The condensing units are more energy efficient.
The Takagi T-KJr2-OS heater is the smallest gas water heater in the Takagi tankless line and is the same as the T-KJr-IN, but for outdoor installation only (Moderate temperature climates). The T-KJr-OS has gas inputs up to 140,000 BTU per hour - can meet all the hot-water needs of a small American home or apartment with one or two bathrooms. The T-K Jr2 OS has an energy factor of 81% to 83%. At an average (rise in temperature) of 60 Degrees F in warmer areas where the winter ground water is 60 Degrees F and with the output set at 120 Degrees F the unit will provide 3.8 GPM, or 228 GPH. The All new T-KJr2-OS has a max GPM of 6.6GPM.
The Takagi T-K4-OS is a mid-sized gas water heater in the Takagi tankless line and is the same as the T-K4-IN, but for outdoor installation only (Moderate temperature climates). The T-K4-OS has gas inputs up to 190,000 BTU per hour - can meet all the hot-water needs of your home, business or condo with one or two bathrooms. The T-K 4 OS has an energy factor of 81% to 83%. At an average (rise in temperature) of 60°F in warmer areas - where the winter ground water is 60°F and with the output set at 120°F - the unit will provide 5.2 GPM. The All new T-K4-OS has a max GPM of 8.0 gmp.
The Takagi T-D2-OS model was specifically designed for light commercial applications in outdoor locations. The Takagi Tankless Water Heater T-D2-OS offers a max flow rate of 10.0 GPM. The four preset temperatures on the unit are: 104°F, 113°F, 122°F, 131°F, 140°F, 158°F, 176°F and 185°F. To achieve any temperatures other than those presets, you will require the TK-RE30 temperature controller, which is included with the T-D2-OS.
The Takagi T-H3-OS is a high efficient, condensing tankless water heater perfect for residential and light commercial applications. With gas inputs of 199,000 BTU, the T-H3-OS-P can produce enough hot water for four bathrooms in warmer climates or three baths in colder climates. Primary heat exchanger utilizes HRS35 commercial-grade copper alloy for 25 times better heat transfer than stainless steel. Secondary heat exchanger utilizes 316L stainless steel for better corrosion resistance. Outdoor model includes remote control as standard feature
The Takagi T-H3S-OS is a high efficient, condensing, tankless water heater perfect for residential applications. With gas inputs of 180,000 BTU, the T-H3S-OS can produce enough hot water for three bathrooms in warmer climates or two baths in colder climates. Primary heat exchanger utilizes HRS35 commercial-grade copper alloy for 25 times better heat transfer than stainless steel. Secondary heat exchanger utilizes 316L stainless steel for better corrosion resistance. Outdoor model includes remote control as standard feature
The Takagi T-H3J is a high efficient, condensing tankless water heater perfect for residential applications. With gas inputs of 160,000 BTU, the T-H3J can produce enough hot water for two bathrooms in warmer climates or 1.5 baths in colder climates.
