PRODUCT DETAILS
Released in 2003, the T-K Jr. 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, as well as smaller commercial applications. 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 efficiency rating of 83%, using natural gas, and 84% with propane. At an average ∆T (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 2.7 GPM or 162 GPH.

Cost-efficient and environmentally friendly, the T-K Jr. can be converted into a direct-vent unit by using the optional TV09 conversion kit (sold separately) for installation in a garage, a utility closet or any confined space in which makeup air may be limited.

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, 140°F, and 182°F. To achieve any temperatures other than those presets, you will require the TK-RE02 temperature controller (sold separately).
