Takagi T-H2S
Nov 14th
The Takagi T-H2S is a new tankless model that Takagi has developed and is now offering. It is available in either Direct Vent or Outdoor models. Takagi’s T-H2S is a condensing tankless that is
very energy efficient (up to 90% EF). The T-H2S was designed for residential applications and is a candidate for the ECOenergy audit rebate program and its $375 tankless rebate program.
The T-H2S Flow
Seeing as the T-H2S is one of Takagi’s greenest tankless models offering an average efficiency of 90% with natural gas and 90% with propane. If you choose this tankless model here in Ontario, Toronto, Barrie, or any of the surrounding cities expect a flow rate of about 4.1 GPM or 246 GPH with an input temperature at 40ºF or less.
Takagi states that the T-H2S tankless can provide at least two showers worth of water simultaneously in addition to one appliance.
Features
The T-H2S can be vented with PVC providing zero clearance for direct vent installations.
PVC venting can be used in all applications and a 3″ exhaust venting option is coming soon.
The TH2S utilizes dual exchangers to maximize the unit’s energy efficiency.
The primary heat exchanger is made of copper while the secondary is stainless steel.
This secondary heat exchanger is used to recover waste heat from the vent stack to preheat
the incoming ground water. This is in fact what classifies the TH2S as a condensing
tankless water heater.

Takagi T-K3
Nov 14th
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
Nov 10th
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.
- 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 $375 Government grant.
- Takagi T-K3 – Low flow activation rate, link up to 4 units in conjunction for increased hot water flow, extra long vent pipe applications (50 feet with 5 elbows). Expect around 4.1 GPM at a 40 degree temperature rise. Does qualify for NRCan audit rebates of 300$ plus.
- 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.

Canadian Tankless Water Heater Websites
Oct 20th
Its funny that most of the major tankless companies dont have canadian version of their websites… Canada is a very natural gas dependant country and thus we have this service in the majority of our homes. You would think that a market of 30 million plus might foster a small investment in a geocentric Canadian content specific website. 
Tankless manufactures know that the further north their product is installed the colder the ground water and the more energy is needed to heat the water up to acceptable temperatures. For the most part all of the major tankless companies have successfully overcome this issue. They certainly should work on advertising and showcasing thier advancements. Canadian tankless manufacture websites would go a long way.

Tankless Warranty Facts
Oct 4th
Tankless systems all seem to have different warranties and information regarding their heat exchangers, parts, and labour on installation. Here is a small break down of what you as a home owner can expect. 
Bosch – 12 year warranty on tankless heat exchanger and 2 years on Parts.
Navian – 15 year warranty on tankless heat exchanger and 5 years on Parts
Noritz - 10 year warranty on tankless heat exchanger and 5 years on Prats.
Rinnai – 12 year warranty on tankless heat exchanger and 5 on Parts, but also comes with 1 year on labour.
Takagi - 10 year warranty on tankless heat exchanger, 5 years on Parts, and 1 year on labour.
It pays to do your research as you can see there is a bit of a difference between the different brands and the warranties that they offer. These tankless systems are designed to last for a number of years, many years longer than your conventional tank water heater.
Also know that the company you hire to do the installation more often than not (if they are reputable) will add additional warranty on to your unit. Make sure to get a few quotes and make the warranty a priority when negotiating the price.
Tankless Brands
Jul 11th
There are a number of different brands of tankless water heaters below you will find a short synopsis of each of each tankless system.
Rinnai Tankless
Easily one of the biggest suppliers of tankless units, they are known for stability and reliability. Of all the experience we have had with tankless water heaters Rinnai’s Tankless is by far the most reliable unit on the market today.
Navien Tankless
This one is often spelled incorrectly as “Navian”. It has been know as the the most efficient tankless with their units reaching 98% efficiency. They have had reliability issues in the past but they are on to the 4th generation now and most of the issues have been cleared up.
Noritz Tankless
Not the most popular brand of tankless but it is a nice unit none the less. Reliability is lacking a bit but it makes it up in its efficiency.
Bosch Tankless
Commonly sold in Home Depots, these tankless systems are good units but they are so frequently incorrectly sized and installed that they have developed a bad reputation due to this.
Takagi Tankless
If for some reason I couldn’t get a Rinnai tankless I would choose the Takagi tankless model for sure, high efficiency, reliability, and easy venting. What more could you ask for?
John Wood Tankless
This brand can be difficult to find in Toronto or Ontario for that matter, its mainly sold in the US and is made by GSW.

Takagi Condensing Tankless Review

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
- PVC venting
- 95% efficient
- 4.6 GPM in dead of winter
- 8.5 GPM in the summer
- 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.

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.
