Released in 2010, the T-KJr2-IN and T-KJr2-OS is the smallest water heater in the Takagi tankless line. But this small, but powerful unit - with 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. Designed to virtually do anything a 40-gallon tank-type water heater can do and more, the compact, wall mounted T-K Jr. can support hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances. The T-K Jr. has an energy factor of 0.81-0.83. 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 3.8 GPM, or 228 GPH. In colder areas where the input temperature may be 40?F or less you can expect a flow rate of about 2.9 GPM or 174 GPH. The All new T-KJr2 has a max GPM of 6.6GPM. Cost-efficient and environmentally friendly, the T-KJr2-IN can be converted into a direct-vent unit by using the optional TV10 conversion kit for installation in a garage, a utility closet or any confined space in which makeup air may be limited. Please refer to "Accessories" for more information on venting options. Using the average of 60?F input water cited above, the T-K Jr. can provide enough hot water for one shower and a lavatory basin at a time; or one low-flow shower (2.5 GPM or less) and an appliance, such as a dishwasher or washing machine, at the same time. For much colder input temperatures, such as 40?F or lower, this unit can provide endless hot water for consecutive uses; that is, running only one major fixture at a time. Please refer to the flow charts for specific rates. The four preset temperatures on the unit are: 113?F, 122?F, 131?F, 140?F. To achieve any temperatures other than those presets, your client will require the TK-RE02 temperature controller.
