Takagi Condensing Tankless

Here is the Takagi T-H2 Condensing Tankless hot water heater, there’s a lot to cover so lets get started.

Takagi Tankless Benefits

1. PVC venting
2. 95% efficient
3. 4.6 GPM in dead of winter
4. 8.5 GPM in the summer
5. Direct vent capability

Info

The T-H2 model is available as a direct vent or an Outdoor model only. Takagi’s T-H2 “2nd Generation High Efficiency Tankless” unit, is a very energy efficient tankless unit (up to 95% in thermal efficiency) in the Tankless industry.  The T-H2 was apparently designed for residential and light commercial use and offers Takagi’s Easy-Link to join multiple units.

The T-H2 can provide upwards of three showers’ worth of water simultaneously in colder climates.

The T-H2 can be vented with PVC, providing 0 clearance for DV installations. PVC venting can be used in all applications and apparently Takagi says that 3″ exhaust venting is now available (previously it required a 3″ intake and a 4″ exhaust).

The primary heat exchanger is made of “Heat Resistant Alloy” HRS35 Copper, Takagi has also added a “High Corrosion Resistant Stainless Steel” #316L secondary heat exchanger to recover waste heat from the vent stack before it leaves the unit to preheat the incoming ground water. This second heat exchanger and the resulting condensation that forms from the high efficiency operation, classify it as a “Condensing” Water Heater.

Specifications

As we all know Canada can has winter, and this affects our ground water temperature.  The higher the tankless has to heat ground water up the lower the output flow of hot water is.  Ontario’s ground water fluctuates with the coldest temperatures occurring in February and the warmest is September.  Toronto, Hamilton, Brampton, Scarborough, Mississauga for example are places that rarely see ground water temperatures dip below 40 degrees Fahrenheit.  Thus its safe to assume a minimum of 4.6GPM in the worst of conditions.

T-K3 – $1495.00

The T-K3 model, also known as the “Revolutionary T-K3,” is one of Takagi’s most versatile and powerful residential units. The T-K3 offers Easy-Link capability, which allows you to connect up to four units without the use of a controller unit. The T-K3 can also be converted to a direct vent model.

Compact Size:

Only 13.8 inches wide, the T-K3 can be recessed between wall studs for even more space savings! A special recess box is available for outdoor installations.

Lower Activating Flow Rate:

The T-K3 activates at only 0.5 GPM, which allows the use of smaller water flows in bathroom sinks and showers. This reduces water waste and allows for stable temperatures.

Parallel Installation:

Using Takagi’s Easy Link technology, the T-K3 can be installed in parallel with up to three other units without the use of an additional control box, generating more flow while saving money, space and installation time. Four T-K3 unites will deliver a total of 21.6 GPM at 60 degrees F delta T; or 26 GPM at a 50 degree F delta T.

Direct-Vent Conversion:

The T-K3 can be easily converted into a direct vent model for inside installations that need to import combustion air from outside.

Eight Temperature Settings:

Instead of the usual four settings, the T-K3 offers eight separate temperatures, set by dip-switch: 104 degree F, 113 degree F, 122 degree F, 131 degree F, 140 degree F, 158 degree F, 176 degree F, and 185 degree F. This versatility reduces the need for a separate remote control. However, setting temperatures other than the eight presets requires the TM-RE10 temperature controller.

Longer vent runs:

The T-K3 can have a vent pipe run up to 50 feet with five elbows, instead of the normal 35 with three elbows.
As you can see, the T-K3 incorporates all those “why-don’t-you-have-this?” features into this one new product. Its larger flow capacity through parallel connections will meet the hot-water needs of most high-volume residential applications and many commercial projects, too. In short, the T-K3 fills the gap between the single residential heater and multiple commercial T-M1 units. Performance depends on the temperature of the ground water of course: At a delta T of 60 degrees F in warmer areas – for example, where the winter ground water is 60 degrees F and with the output set at 122 degrees F – the T-K3 will provide a 5.4 GPM, or 324 GPH. In colder areas where the input temperature may be 40 degrees F or less, expect a flow rate about 4.1 GPM, or 246 GPH.
