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.

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 Update
Jun 22nd
Here at the tankless water guide we are undergoing to a new web site redesign. Over the last few years we have grown substantially and the site is now visited by hundreds of people a day looking for tankless information and installation quotes. The new design will help users access information easier and hopefully provider a better flow to your tankless browsing needs.
Comments are open on this post if anyone wants to add some input.

Navien Problems

Navien Problems
|
Navian was the first to come out with a condensing tankless water heater and thus they are bound to have some issues. This post is aimed at addressing some of these problems.
Issues
- Navien flow sensor issues
- Navien Control board failures
- Navien Heat exchanger cracks
The flow sensor
Early Navian models had flow sensors that would easily corrode and shut the unit down as the buildup would impair operation. There is a temporary fix where you take the two clamps off the sensor, pull it out and blow on it. The fix that Navien has made is to change the sensor over to stainless steel, you can replace the part to prevent this unexpected shut down. Also an additional fix is to install a 5 micron filter in the water inlet right before the Navian.
Navian Control Boards or Motherboards
These do fail relatively frequently and symptoms would be that the unit turns on, then off, then on, and then off repeatedly or possibly, fails with error code 03 (ignition failure). There are a few other issues that the board can cause but the only real solution is to power cycle the unit (un-plug and plug back in) or replace the Navien control board.
Cracking Heat Exchanger
This isn’t near as frequent as the problems listed above but it is an issue none the less. A heat exchanger should be replaced immediately; it’s a breach containment allowing exhaust gases to enter your home. The heat exchanger is under Navian warranty.

Takagi Condensing Tankless Review
Mar 16th
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.

| Weight | DV = 73lbs. | |
| Dimensions | 25.6″ x 18.5″ x 12.4″ | |
| Ignition | Electronic Ignition | |
| Electrical Supply | AC 120V (60 Hz) | |
| Water Pressure | Min. 15psi | Max. 150psi |

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.

kilometer range. Our 4th largest province is nearly twice the size of the largest continental US state.
Thus we have a difficult time providing tankless water heaters to all of Ontario never-mind the rest of Canada, but we try our best. Below is a map of our primary service area where we are able to complete home energy audits and provide service and installation. We are selling individual units with no installation and these can be shipped nearly anywhere but for the most part you may find a cheaper unit near your home. If you’re inquisitive though send us a quick email and we can provide a price and shipping quote.
Energy Audits
- Tan area – basically all of Ontario could be a week or more depends on where the next available auditor is.
- Green area – roughly 2 to 5 business days
- Pink area – usually within 1-3 days
Tankless Unit only
- We routinely have units shipped within the same day of purchase (it does depend on the unit requested and if its one we have in stock)
Tankless Unit with Quote and Installation
- Green Area - We can usually have a guy out to do a preliminary inspection and solidify a quote within 2-4 days and installation in another few days
- Red Area – Quote and installation is routinely completed in under a week
Service Calls
- We service most of southern Ontario and can do emergency calls, depending on where our service techs are we can sometimes be at a customers house in under 30 minutes.
See the contact page here (Contact Us) for more information on how we can be reached.
Thanks From Tankless

Thanks

Just want to thank everyone for submitting your information to our HUB. We have been inundated lately with requests for tankless water heaters and thus we are trying to call you all back to setup appointments as soon as possible. It can take upwards of 24 hours to hear back from us, but occasionally it can take less than 5 minutes from when you send the form request in.
Over the last few years we have installed thousands of tankless heaters and have received hundreds of compliments on these systems. It’s easy to accept this
praise when the system offers endless hot water at a fraction of the cost of a conventional water heater.
If you’re thinking of getting into a tankless water heater for your home now is one of the best times to take the plunge. Initially the cost is higher but the benefits far outweigh the small price gap between conventional and tankless. Government grants are at an all time high but are ending soon so get your $700 plus rebate before the program ends.
