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.

Tankless in Richmond Hill
|
We install tankless water heaters in much of Ontario and Toronto but Richmond Hill always has a lot of tankless systems installed. This is a city with a high percentage of Tankless water heaters to conventional systems. This high number could be attributed to a few things. Firstly, within Richmond Hill it is easy to swap out any existing rental 
tank to a high efficiency Tankless water heater. Also Richmond Hill is on Enbridge additionally this makes it a simpler task to swap or change up to a Tankless water heater.
Remember government grants for a tankless system are between $630 and $750. So you can use that to offset the additional cost that a tankless system costs over a conventional tank.
If your interested in a tankless water and live in Richmond Hill then fill out the quick form here and we will get back to you as soon as possible to answer any questions you may have.

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.

| Water Pressure | Min. 15psi | Max. 150psi |
| T-H2DV Manifold Pressure | Natural: 3.15″WC | Propane:4.6″WC |
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.

Cleaning your Tankless

Cleaning Your Tankless
|
We get a lot of questions regarding the cleaning procedures on a tankless water heater, we have come up with a thorough document for you to follow. This document is in PDF format so you will need a PDF reader (they are free). You can download the document here DOWNLOAD – Download instructions to clean a tankless water heater.
Here is a little excerpt taken from the document in step 5.
“When flushing is complete and before the lines are removed, verify that the purge port valves are closed and remain in this position. You can now remove the lines and reinstall the purge port valve caps, ensuring that the rubber washer is in the cap, and tighten. (NOTE: To prevent damage to the rubber sealing discs (washers), do not over tighten these caps.) ”
Remember that Ontario and even Toronto for that matter has quite varying degrees of water hardness, owners of Tankless systes should be aware their particular situations and develop a schedule that reduces the amount of buildup in their tankless hot water heaters.
