The Noritz NRC111 is a condensing tankless water heater.  This is the only condensing tankless that Noritz makes and it produces 11.1 gallons of hot water per minute.

The Noritz NRC111 utilizes a dual heat exchanger, which is made from a fusion of stainless steel and copper exchangers.  The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger.  This results in dramatic reduction of carbon dioxide and increases the tankless heater’s efficiency level to over 93%!  Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting. A PVC adapter is built into the Noritz heater for easy installation.

This chart pits the two main tankless systems that each manufacturer produces, the only row it is missing is reliability.  Unfortunately we dont have any scientific data on that but would venture to say that the Rinnai makes the more dependable tankless.  This is solely based on comments that we receive here on the site regarding the two tankless manufacturers.

The specifications and features on any of the Rinnai tankless product lines are on par with all other major tankless brands, they consume similar amounts of gas, produce very similar hot water quantities, and have nearly the exact same efficiency ratings.  Day in and day out the Rinnai tankless just works, it never breaks down and that’s what makes it stand out. 

Rinnai Models

The Rinnai tankless units that are installable in Ontario are:

• RC80HPi
• RC98HPi
• R50LSi
• R75LSi
• R98LSi (commercial)

The RC80 and RC98 are both condensing units and have a energy factor of 94%

The R50, R75, and R98 are conventional tankless systems with an energy factor of 82%

Tankless Grants for Rinnai

All Rinnai units available for Government grants – you can find out how much you are eligible for on our Grants Page.

Sizing a Rinnai

Why Rinnai is different:

As a consumer you simply cant purchase a Rinnai tankless and have your local plumber install it, the dealership has strict sales rules and policies in place to prevent this.  To become a Rinnai tankless dealer all of the installers have to go through special training to ensure that each and every tankless is installed within all specifications.  Yes, this is a significant factor to why Rinnai’s reliability factor is so high.

Its difficult if not impossible to size a tankless without first surveying the home that its being installed in, there is a rough guide that you can follow though.

1. RC98 and RC80 – Tankless condensing units that can handle between 8 and 9.8 GPM suitable for nearly all homes (except for really large one 4000 sqf and up).
2. R75 – Very universal tankless suitable for nearly all homes, produces 7.5 GPM (caution should be taken on installs for larger homes).
3. R50 – Smaller tankless suitable for smaller homes and cottages. The unit produces 5.0 GPM.

Rinnai Costs

Again this is nearly impossible to predict as every home is unique as well as every install.  The unknowns are installation rates, venting pipe length, venting issues, mounting locations, gas piping, water piping, etc. But the unit is a fixed price and can cost anywhere from $1500 to over $4000 (that’s installation included as you cant just buy a unit).

Bosch vs Rinnai Tankless

There has been quite the buzz regarding tankless water heaters lately.  Claims of their superior energy savings and efficiency have been touted by every company pushing the units.  Yes they do reduce the amount of gas or propane you use but they also provide endless hot water.  If you take a 45 minute shower your more than likely using more energy than you would with a conventional tank that simply runs out of hot water after 20.  Yet if you are reasonable and shower for the same duration, you have great potential to see some real energy (and money) savings with a tankless water heater.

Now that you know you want a tankless you have two options…

Option 1 –  Go to your nearest Home Depot and purchase one from there, then hire a gas fitter and a plumber to install it

or

Option 2 –  Look for a professional tankless installer who has the specialty to preform a stand-up job.

Being the person purchasing the system cost will obviously be a factor and I guarantee Home Depot will be the cheapest option (If cost is your only driving force you should click the link and head to Home Depot now).

For those of you that stuck around I will explain why the second choice is probably the best choice.

Firstly if you call around to a few tankless installers you will quickly realize that none of them sell Bosch tankless heaters (Bosch is the only tankless brand Home Depot sells). The reason why these companies don’t offer this brand is due to the fact they offer extended warranties and guarantees.  They are on the line for the products they sell and thus they go with quality products they know will stand up  and remain reliable.

Enter Rinnai.

Ask these same tankless installation companies if they sell the Rinnai brand tankless water heater and I bet you find that 99% of them do. Rinnai tankless water heaters are built to last and this is why industry professionals install this brand. Lets compare the Bosch and Rinnai tankless models and see some of the differences.

Bosch Aquastar Tankless Water Heater 1600H compared with Rinnai R75LSi Tankless

Bosch Tankless Verses a Rinnai Tankless

As you can see there are some definite differences, probably the most glaring is the amount of hotwater that can be provided.  The Rinnai is able to produce more than twice as much, meaning you won’t run into problems when running more than one appliance or faucet..

Of course this doesn’t take into account all the benefits that you get from a professional install like:

• Proper venting, tankless systems have very specific code requirements

• Correct sizing so that you always have enough hot water

• Additional warranty and workmanship guarantees

• Maintenance guarantees, service plans, and emergency tech service.

Sure any Ontario Home Depot has the cheapest system but I hope I clarified why they’re some much cheaper.  Now those of you still left reading option 2 and didn’t click on the Home Depot link you are obviously interested in a tankless.  These systems can’t go in every home due to venting issues so we send out a technician to make sure everything will work and what size tankless  your home would need. This is a free service, so just fill out the form below and we will call you to schedule a time for someone to come by.  Typically only 15-20 minutes.

Technicians are fitting and sizing tankless water heaters in all of the greater Toronto area as well as, Hamilton, Burlington, Oakville, Etobicoke, Mississauga, Rexdale, Richmond Hill, Vaughan, Markham, North York, Scarborough, Im sure I have missed some cities but you get the idea, if in question just send us an email.

Norits Tankless Hot Water

We are now starting to install the Norits tankless systems to replace the Navien that we have had some troubles with. The Norits is a condensing tankless that is able to provide sufficient hot water for the typical 3 bedroom 3 bathroom home.

Nortis Advantages

1. 0.5 GPM low flow start up requirement
2. Direct ignition
3. Condensing so
4. Greater than 93% efficient
5. Digital thermometer for accuracy
6. Dual copper primary heat exchangers
7. Multi-system compatibility
8. PVC (636) venting capabilities

The Noritz 842 tankless water heater also uses a dual flame in its burner. This is a system that recirculates the exhaust gases back into the combustion chamber to burn off any excess fuel and particulate mater so as to increase efficiency and provide, essentially free heat.

Single Burner

Dual Burner

These energy efficient models use dual heat exchangers to increase efficiency to over 93%.  Available form Norits are the N-0842MC and the N-0842MC-DV, the tankless come in either direct or power vent.

Fill out this form and see if the Norits tankless will work in your home.  CLICK FOR FORM

Noritz is correctly spelled with a Z instead of an S but its a common mistake.

Rennai Tankless water heater

Rennai tankless or Rannai tankless is actually spelled Rinnai, it is commonly misspelled as Rennai condensing or Rannai condensing. Here are some more spelling errors for Rinnai tankless water heater.

1. Rennai Tankless
2. Rinai Tankless
3. Renni Tankless
4. Rinni Tankless

For the Record it is Rinnai.

Here are some Rinnai Facts

- Uses concentric venting which results in only one hole drilled in your wall but this results in a reduction of venting options.
- Lowest failure rates.
- 10 years parts and labour warranty
- Made in Japan
- 8.0 GPM hot water production on most units
- More than 30 million units installed world wide
- No pilot light (direct electronic ignition)

This picture is an example of the vent pipe that a Rinna tankless uses.  Basically there is a pipe inside a pipe, one directs exhaust gases out of the house, while the other allows fresh air to flow in from outside directly to the combustion chamber.

So for the record it is Rinnai.

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

1. PVC venting
2. 95% efficient
3. 4.6 GPM in dead of winter
4. 8.5 GPM in the summer
5. 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.

Specifications

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.
