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.

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.

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.

Takagi Tankless Condensing Unit

The Takagi Flash T-H1 tankless water heater is a new condensing unit available to house hold consumers. 
This tankless heater has an average efficiency of 95% with propane as its fuel source and 92% when natural gas is used. In our Canadian climate you can expect about 4 plus gallons per minute in the dead of winter, and much more in the summer when ground water is warmer.
The Flash T-H1 is able to provide about 3 simultaneous showers when ground water is at or below 40 Fahrenheit. This tankless is unique in that it has two heat exchangers which enable the water passing through to absorb much (90 to 97 percent of it) of the heat generated from combustion. The stainless steel secondary heat exchanger has been added to collect waste heat from the units vent stack and divert it to pre-heating the incoming water. This secondary exchanger causes some condensation that is slightly acidic, Takagi has included a collector and a built in neutralizer that allows the drainage to be plumbed into your standard drainpipe.
This tankless water heater employs a variable gas input which allows the unit to produce only the amount of heat necessary to warm the water to a household’s desired temperature. At a maximum this tankless can produce 199,000 BTU’s per hour and in ideal conditions provide 10 gallons of hot water per minute.
There is a downside, the Takagi condensing tankless water heater is quite expensive, but it is one of the higher end units with a very high efficiency rating. Also unless you buy the Takagi temperature controller you are limited to only 4 preset temperatures, 113 F, 122 F, 140 F, and 182 F.
This is a very interesting system but we havent had any direct hands on experience to draw on yet. We should be getting a trial system soon at which point we will provide a new update and evaluation.
