Heat Exchanger

Navien tankless water heaters utilizes dual stainless steel heat exchangers, providing 3.8 to 4.5 times longer life-expectancy and erosion resistance over the copper heat exchangers used in other tankless brands. Navien’s heat exchangers operate with relatively low water temperature, minimizing damage from hard water conditions and maintains efficiency levels. Its always important to have your tankless flushed once every 2 years or so to remove any buildup from within the heat exchangers.

Efficiency

Because of Naviens high efficiency the tankless can be vented in PVC piping. Basically excess heat is exhausted with all the combustion gasses in conventional tank systems but a Navien uses this to further heat the water. This results in significantly lower exhaust temperatures and allows for the use of PVC exhaust vent piping.

Takagi T-K3

The T-K3 model is one of Takagi’s most versatile and powerful residential tankless water heaters. The T-K3 has Easy-Link capability, allowing owners to connect up to four units without the use of a controller unit. The TK3 can also be converted to a direct vent model to further extend its application in residential homes.

Features

This Takagi TK3 tankless has a number of features that allow it to stand out from the pack.

Compact Size: Only 13.8 inches wide, the T-K3 tankless has the ability to be recessed between wall studs for even more space savings.

Low Activation Flow Rate: The Takagi TK3 activates at only 0.5 GPM, which allows the use of smaller water flows in bathroom sinks and showers. This is a pretty standard flow rate now for new generation tankless water heaters.

Parallel Installation: Easy Link technology allows the T-K3 to be installed with up to three other units without the use of an additional control box.

Direct-Vent Conversion: The TK3 can easily use a direct vent conversion to import combustion air from outside.

Eight Temperature Settings: Some tankless manufactures have only 4 preset temperature settings, the T-K3 offers eight separate temperatures. However, if you want a specific temperature than it is required that you buy 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. This can be a great addition if your particular installation has a long vent run.

Synopsis

The TK3 tankless incorporates a number of important features into one new tankless system, and should fit the needs of most high-volume residential applications. As always performance depends on the temperature of the ground water, and with winter water temperatures here in Ontario, Toronto and the Toronto region dipping to the low 40 degrees F range you can expect the T-K3 tankless to produce a flow rate around 4.1 GPM, or 246 GPH.

Takagi Tankless

Takagi tankless water heaters were the first to enter the North American market around 1995. Although they had more than perfected the tankless having manufactured their systems in Japan for over 50 years prior. Takagi is committed to quality and innovation and they have done a good job with excellent reliable systems. It would not be a mistake to install a Takagi tankless in your home.
Takagi has a few popular tankless models and here in Ontario you would probably be installing one of these systems.

  1. The T-H2 – Green, 2nd generation condensing tankless, 4.6 GPM (40 degree ground water temp) and can be vented with PVC piping. It’s a great system that meets the NRCan audit program requirements for high efficiency and qualifies for a $375 Government grant.
  2. Takagi T-K3 – Low flow activation rate, link up to 4 units in conjunction for increased hot water flow, extra long vent pipe applications (50 feet with 5 elbows). Expect around 4.1 GPM at a 40 degree temperature rise. Does qualify for NRCan audit rebates of 300$ plus.
  3. T-K4 Takagi is a new tankless that can be installed indoors and out, designed for easy venting and lots of hot water production. The T-K4 can produce up to 8 GPM, impressive for a tankless water heater. Built in power venting system.
