Your Installer knows
Nov 23rd
You live in Toronto, Mississauga, Hamilton or one of the cities located nearby and your interested in a tankless water heater so you Google it, researching brands, models, venting and everything in between. You decide on a Navien tankless as it seems to have the best of everything. We are going to try and talk you out of it. The thing is most of the time people always search for the positives, try Goggling ‘Navien problems’ and you will find an entire underworld containing copious amounts of frustrations and little hacks to try and get these units running as they are plagued with problems.
You know your house inside and out as well as how your family uses water, but your installer knows tankless systems. You both need to listen to each other when determining the right brand and size to install.
An installer or company dealing with tankless systems installs them everyday they know the ins and outs of the different brands. Its likely that they will recommend a brand as they know its dependability.
Some Tips To Ask The Sales Representative
- Every tankless needs unique venting to meet Government requirements, if someone says they can sell you one over the phone…. RUN
- How many hot water applications can run simultaneously (eg. dishwasher, sink shower)
- Ask for a breakdown of costs
- Ensure you get the exact model they plan on installing and try a quick Google search on it
- Make sure you get your warranty printed on the contract
- Do they have experience installing in Toronto or surrounding areas
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.

Takagi T-K3 – $1495.00

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.

Tankless Purchasing Guide

Guide For Tankless Purchase
|
Did you know that in your home you are probably paying $60.00 or more per month to simply maintain the heat in a conventional tank type heater? How is this possible? Its simple, your regular tank loses its heat up the flue, or out the chimney, then when the water cools it reheats, and send more money and heat out the chimney. This is occurring even while you’re sleeping or at work.
You likely use most of your hot water in the evenings and morning, do you ever run out? Tankless water heaters are able to overcome these problems. A tankless never runs out of water and can have efficiencies in the high 90’s, you will never run out of hot water in your shower with a tankless.
All of the Earths resources are finite and thus as supplies become scarcer prices will continue to increase, minimizing your consumption reduces your bills. A tankless uses energy only when you ask it to provide hot water, a conventional take keeps water hot even when you’re not there, costing you money. Tankless water heaters will save you more money over their lifespan (20 plus years) than it will cost for the new unit. Plus a Tankless water heater takes up limited amounts of space, is easy to clean, and is easily operated.
Tankless Brand and Venting. With all the different brands available to consumers there is a plethora of venting options to vent the various units. Some tankless water heaters can be vented horizontally and others can vent vertically. The majority of tankless water heaters also have computerized safety devices to protect consumers. Most conventional tanks don’t have these advanced safety features.
Applications and Uses. Some applications of tankless water heaters are: boats, mobile homes, RV’s, and radiant heating systems.
Return on investment. The payback period for tankless water heater is between 3 to 7 years, this is dependent on both energy cost and personal use. If you are a high hot water consumer it will speed up the payback process, if you normally use very little hot water then the payback takes a little longer. Remember though, tankless hot water heaters experience zero standby heat loss and this are much more efficient than conventional tanks.
Energy Audits. Currently the Ontario Government has an incentive program that promotes home energy efficiency. It starts with a home energy audit that assesses the current efficiency of your home, after it is completed a report outlining the current state is sent to the home owner. There is an 18 month period for any renovations to take place; once they are completed a follow up audit is preformed to confirm that all retrofits have been accomplished. At this point grants and incentives are sent from the government to the retrofitted home owner to offset some of the costs.Just installing a tankless water heater qualifies you for $500. Check out the Audit page HERE.
Tankless Lifespan. The expected life of a tankless water heater is roughly 20 years. We have customers who still have their tankless water heaters and it has been in service for more than 20 years. A major reason for this is that tankless water heaters are serviceable, unlike conventional (disposable) tank type water heaters.
