Rinnai Tankless
Jul 15th
The Rinnai tankless water heater is one of the best brands of tankless systems out there. This is simply because the unit is reliable.
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.
- 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).
- R75 – Very universal tankless suitable for nearly all homes, produces 7.5 GPM (caution should be taken on installs for larger homes).
- 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).
Rebates
Jul 13th
Rebates Are Still Available!
Most people think that the Eco Energy rebate program has ended but it is still ongoing and it will likely be re-instated upon its scheduled closing. 
If your interested in getting a tankless water heater for your home then you can still be eligible for rebate and grants from the Canadian Government to offset the higher cost of the tankless. You will need to participate in the Government Eco Energy Audit Program to become eligible for the grants.
The Energy Audit tells you information about your home and is a lot of value to most home owners, you will also gain access to grant money for home insulation, toilets, furnaces, air conditioners, etc.
How much rebate for a Tankless?
This is a common question and it changes with the tankless water heater you buy. You can expect $315 for any tankless that has an efficiency rating below 92%. If you go with a condensing tankless which will bring your efficiency rating up in between 94% to 98% you will receive $375.
Tankless water heaters are notoriously difficult to install and thus a representative needs to come out and assess your home. They can answer any further questions you have and help decide where you would like the unit installed (remember it mounts on the wall).
Whats Involved In A Tankless Install?

What We Do
|
So you are interested in getting a tankless water heater, here is a run down of what you can expect if you decide to choose us for the purchase and install.
Firstly we send a REP out to your home to assess and determine if a tankless system can even be installed. Tankless water heaters have additional venting and placement codes that have to be met for a system to be installed, on average 20% of homes are unable to vent legally. Next the REP will determine your needs and your water usage, looking at the number of people living there, number of bathrooms, and amount of appliances that require hot water. Then the info is presented to you the home owner and you will need to choose if you want to go for a regular tankless or a high efficiency condensing tankless water heater. All prices and cost will be shown and explained to you for your unique home and venting requirements.
If you decide to go with a tankless and before anything is done, if the home owner chooses we facilitate a home energy audit which costs $325 but gives $630 to $750 back automatically with any tankless install. This reduces the net price on any tankless water heater by $305 to $450 instantly, not to mention if you decide to perform any additional upgrades on your home (toilets, windows, furnace, air conditioner, insulation, etc) your able to receive the grants available from the government on those upgrades. OK, so energy audit is done.
Your old tank is removed and the new tanklesswater heater is installed, this takes roughly 3-5 hours depending difficulty. If you are on a rental contract for your old tank type water heater we will take care of all paper work and have the tank returned so you are not charged for it. If you owned the old tank we take it away and dispose of it properly (unless you want it for some reason).
Thats Pretty much what happens when you decide to have a tankless water heater installed with us. If you want further info fill out the form here and we can call or email any additional info you are looking for

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
- 0.5 GPM low flow start up requirement
- Direct ignition
- Condensing so
- Greater than 93% efficient
- Digital thermometer for accuracy
- Dual copper primary heat exchangers
- Multi-system compatibility
- 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.
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.

Rennai Tankless water heater

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.
- Rennai Tankless
- Rinai Tankless
- Renni Tankless
- 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.
