The T-K Jr. is the smallest unit in the
Takagi line-up and offers direct vent capability and power. The T-KJr is
perfect for light residential (i.e. small apartment units) and radiant
heating applications.
Released in 2003, the T-K Jr.
is the smallest boiler in the Takagi line. But this small,
but powerful unit - with gas inputs up to 140,000 BTU per hour - can meet
all the hydronic needs of a small American home or apartment, as well as smaller commercial applications. Designed to
virtually do anything a 40-gallon tank-type boiler 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 for installation in a
garage, a utility closet or any confined space in which makeup air may be
limited.
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, your client will require the
TK-RE20 temperature controller.

Safety is top of mind
for Takagi. When thinking about product safety, consider the following:
 |
Consistently
safe temperature: All
of our units are factory set at 122°F, offering a safe
and steady temperature with computer controlled precision. |
|
Venting
: All Takagi water
heaters use the safest venting on the market today. The venting seals the exhaust from the top of the unit
through the exterior and the built-in exhaust fan ensures
any harmful fumes are fully expelled from the home every
time the water shuts down. |
|
Safety
Devices: Takagi uses
smart safety and monitoring devices to ensure that the
system is working flawlessly. Computerized electronics
allow a Takagi water heater to monitor itself, so you
won't have to. |
|
Safer
In An Earthquake: With
a Takagi, there is no pilot light to ignite flammable
vapors and no heavy tank to fall or pull pipes out of the
wall, eliminating the risk of scalding from ruptured hot
water pipes as well. |
