Navien Tankless Recall In Ontario – Poisoning Risk – Models and Model Number
Jan 5th
Navien tankless has issued a recall on thousands of tankless systems that have pose a risk of leaking carbon monoxide and poisoning homeowners.
Navien is located in South Korea and has been manufacturing it’s tankless water heater for several years now. There are a suspected 13,000 units with the defect and recalled. An unstable connection can cause the vent collar to separate or disconnect allowing exhaust and carbon monoxide to leak into the home.
Tankless water heaters are a green appliance that is able to heat water instantly saving consumers money and energy. A tankless eliminates the need to have a standing storage hot water tank that needs to be heated continuously.
The affected Navien tankless systems that are being recalled were sold to distributors from February 2008 to March 2009. They have been described as:
Navien tankless hot water heaters are white with “T-Creator” and “NAVIEN” on the front. Recalled model numbers are CR-180(A), CR-210(A), CR-240(A), CC-180(A), CC-210(A) and CC-240(A) manufactured in 2008. A label on the side of the water heater lists the model number along with the manufacturing year in YYYY format.
These units are installed indoors in basements and closets (typically in Canada and the northern US). The units that are installed outside are not affected and not being recalled.
If you discover you have one of these models you can schedule a free repair but should not use the water heater in the mean time. Navien also suggests that a carbon monoxide detector be installed outside the sleeping areas of homes.
For more information you can contact Navien at (800) 244-8202 between 8 a.m. and 5 p.m. PT Monday through Friday.

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.
