Navien Rebates
Oct 19th
Navien Tankless water heaters are available for rebates sponsored by the Ontario Government. These cash incentives have been put in place to help convince you the home owner the switch to a more efficient home water heating system. Newer technology comes with higher costs and these rebates help to offset the cost of a tankless water heater.
So you have decided to go for a Navien tankless water heater, how much can you expect to get back?

The Best Tankless Water Heater

The best Tankless ?

This is a controversial question as some tankless water heaters result in a much better fit than others and thus they may be considered better by some users on different situations.
We have facilitated the installation of thousands of tankless systems and ensured that additional warranty and extended service is provided on all of the installed systems. In terms or reliability the Rinnai tankless heater is by far ahead of all the competition. Service records are able to prove this statement, emergency maintenance personnel are rarely called to fix the unit.
The Rinnai R75 is one of our biggest sellers.
- 12 year heat exchanger warranty
- Max input of 180,000 BTU
- EZ connect (2 unit connection)
- 7.5 GPM
- Energy factor of 0.82
- Concentric venting
- Reliable
It should be noted that Rinnai has very particular venting requirements that make it a bit more difficult to install. The specialized vent pipe is concentric meaning that the exhaust pipe is inside the intake pipe. This means that the hole drilled in the wall is at minimum 5″ in diameter. What makes it such a great unit is its reliability, Rinnai systems rarely break down.
The Navien tankless is a big seller as well; it has the condensing aspect of the market cornered. This condensing technology brings the efficiency of the unit up into the high 90’s and makes it the most efficient tankless. Do note – There have been issues and we are servicing this tankless more than any other we have installed.
The Navien CR210A is the primary tank installed.
- Max input 175,000 BTU/h
- Energy factor of 0.95
- 7.6 GPM
- Buffer tank and circulation pump
- PVC venting
- Cheap and Reliable (2011 models and newer)
The water quality in Toronto and surrounding areas like Mississauga, Brampton, and Caledon (Peel region) is considered moderately hard. Vaughan, Markham, Richmond Hill, or York Region has hard water due to the Oak ridges moraine and deposits within it. City of Toronto, Pickering, Ajax, and all cities along the shore of Lake Ontario that rely on the lake for water have moderately hard water. This is important to know as a tankless water heater can collect deposits causing the systems efficiency to be reduced. It is important to clean your Tankless water heater on a yearly basis.
There are a number of great tankless water heater brands available in the market place currently. The new version of the Navien condensing tankless seems to have far fewer issues. Also most of the manufactures have developed and now sell condensing units.
Takagi TH-2 is a great condensing tankless
Rinnai has condensing unit available that works amazing as well — RC98 Brochure
Noritz also make a very good condensing tankless.
All of the units mentioned above have very similar stats and performance, thus its boils down to the situation. Get a few quotes and go with an installer that’s not quoting you the bottom of the barrel price, you will get what you pay for. The brand of tankless that you choose will be determined in part by you and the layout of your home with regards to venting and code requirements.

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.

Conclusion
If you are looking for a condensing tankless that is relatively cheap and flexible for installation the Takagi condensing unit is definitely one that you should consider. This unit is $2575 our price and the Suggested Retail is $3920, which is considerably more.

Condensing verses Non-Condensing Tankless
Mar 27th
Condensing verses Non-Condensing
|
Tankless water heaters come in two different efficiency styles, condensing and non condensing. A condensing unit will recover more than 85% of the gas that a regular tankless water heater would otherwise vent out. Navien or “Navian” makes a tankless system that is 98% efficient by employing the condensing system. The high efficiency is gained by allowing the relatively warm exhaust gases to transfer otherwise wasted heat to the incoming water preheating it before flowing through the primary heat exchanger. This adds about a 10 to 15 percent efficiency increase to a tankless water heater which in itself is already quite efficient.
Now the grants that are available from the provincial and federal government are 
different for a condensing and non condensing tankless water heater. A condensing unit will receive $600 in total grants or $300 from each government level. The non condensing unit will net you $250 from provincial and federal netting $500 total. The governments trying to reduce energy consumption and pollution emissions would naturally give more grant money to tankless water heaters that are the most efficient.

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.
Navien Tankless Water Tank

Firstly let’s get this straight; Navien is a brand of tankless hot water heater not Navian.I have seen this 
spelled wrong many times, Navian (I googled it) is nothing, definitely not a tankless water heater.
Navien has 6 residential models (CR-180, CR-210, CR-240, CR-180A, CR-210A, CR-240A) and then 3 commercial units (CC-180, CC-210, CC-240). These tankless water heaters are all relatively similarly designed but as you go up in model number you increase the amount of hot water the tankless unit can provide.Here is a quick list of each units performance.
- CR-180 and 180A are able to provide roughly 3.8 gallons per minute with a 77 degree F rise.
- CR-210 and 210A are able to provide roughly 4.5 gallons per minute with a 77 degree F rise
- CR-240 and 240A are able to provide roughly 5 gallons per minute with a 77 degree F rise
We should definitely look at the efficiency of the Navien tankless water heater which is currently the only condensing unit on the market.This extra step gives Navien the efficiency title, currently rated at 98%, therefore 98 cents of every dollar spent on heating your water is actually turned into hot water.This is an amazing number as most tankless water heaters are 10% to 15% less efficient. Of course being the first on the block has its issues, the Navien tankless water heater is facing some problems from rubber hoses becoming blocked. This has been reported numerous time in several forums around the internet.
The good thing is that most of the other Tankless water heater manufactures are working on their own form of tankless condensing units.This should give the consumer a good choice in high efficiency water heating.

Navien UPDATE-2010
This write up was done in February of 2009 so its been over a year now and there are a number of alternate condensing tankless water heaters available now. Navien was the first on the block and realistically you cant beat the price of the unit, even today its still lower than all condensing tankless units. Sure there has been some issues regarding the system but thats to be expected from a new technology (we will be authoring a new post on all these problems and their fix, check back soon).

Navien UPDATE – Feb 2012
Navien has spent a lot of time reworking their tankless water heaters and removing all the bugs and issues that have plagued them in the past. I feel more than confident in 2012 to recommend their new tankless water heaters.
