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.

Hot water heater grants for your home
Take advantage of Government of Canada grants for replacement hot water heater systems:
- Canada ecoENERGY — Homeowners can get up to $1,250 in grants from the Canadian government for a new hot water system. The Government of Canada grants up to $5,000 for home energy renovations through the ecoENERGY Retrofit – Homes program, which is in effect until March 31, 2012. Click here for more
Remember not to long ago I talked about how a tankless could be combined with a solar thermal water heater? Well BAM! here are some rebates the Government is offereing that reduce the cost for both the tankless and the solar heater. I wouldn’t expect these to last too long (in fact, around April 2012 is when I would expect to offer to be removed).
ecoENERGY Grants and Rebates
Nov 2nd
The ecoENERGY Retrofit for residential homes is creating jobs and helping Ontario residents save money. These changes help to reduce energy bills now and in the
future. BUT you need to act quickly, funding for the grant program is limited and everyones evaluations and retrofits need to be completed before March 31, 2012 or you will missout.
This ecoENERGY retrofit program has a specific section for tankless water heaters as they’re very high efficiency systems compared to what has conventionally been installed in homes. In Ontario you can expect a $375 rebate from the Government if you decided to switch over to a high efficiency tankless.
Several tankless brands are able to deliver the required efficiency and all bring in the full rebate value. If your interested you can read more about the different tankless brands and their specifications below.
Eligibility for the ecoENERGY retrofit program in Ontario

Mike Holmes on Tankless Water Heaters
Aug 16th
Still doubting the validity of a tankless water heaters for your home? Famed home renovation TV star Mike Holmes goes on record saying that the systems just plainly “make Sense”.
Below is a excerpt from the article.
“Environmentally responsible building is opening our eyes to some great, new technologies. But it’s also getting us to take another look at really smart old ideas — such as tankless water heaters.
These have been used in Europe and Asia since the Second World War, but are only now coming into common use in North America. I’m a huge fan of these in-line hot water heaters. They are super efficient, space-saving products that — when installed properly — will last almost forever, cut your energy bill and supply unlimited hot water to your home. You can literally open up your tap, walk away, and still have hot water coming out a month later.
Yes, they cost more initially, and you have to have them installed and calibrated to your household’s use by an expert, but there is no doubt in my mind that you will get your money’s worth.
Tankless water heaters are small — usually not much bigger than an electrical panel. When you turn on a hot water tap, a burner in the unit lights up and instantly heats water in a maze of copper pipe. With the tap open, the water flows through the heated pipes, and within seconds, you have continuous hot water. When you turn off the tap, the burner goes off. The result is you don’t have to heat and store 40 gallons of water in your basement any more. You only heat the water you use, and you have hot water for as
long as you need it.”

Paloma Tankless Hot Water Heater

Paloma Tankless Water Heater

Andy talks about the remote control option on the Paloma branded tank, its important to know that these systems are able to support multiple remote control points at various locations in the home. This makes it convenient for adjusting water temperature right at the source, say a shower or bathtub. This is a feature that most manufactures are supplying with their tankless units.
Solar Water Heater and Tankless Update
Apr 21st
Solar Water Heater and Tankless
|
One of our readers is working on installing a domestic solar hot water heater in conjunction with a tankless. They were going to go with a Rheem tankless to offset any additinonal temperature increase that was needed over the solar gains. Unfortunately they found out that the particular unit that they were planning on using senses the incoming water temperature, buy ‘ignores’ water that is within 40F of the target temp (ie. the unit won’t cut on to work). This has caused them some problems because:
1) The max output on any residential line is 120F (49C) (this is canadian law it cant be any hotter than this in a residential home).
2) If the solar heated water comes in at 100F (37C) or warmer, the unit will not kick on. This means the output is 37C, a cold shower to be sure.
3) If you go to the commerical unit, the max temp is 180F. This much too hot for residential use (think of someone turning on the hot water at the sink to do dishes), but it would work from the 40F differential standpoint (ie. if the water is 60C or colder, then the unit will fire, anything warmer than 60C doesn’t matter as it would be warm enough for a shower). Again this is illegal in Canada as the Max allowed Temperature is 120F.
The best solution is to more to a Rinnai Tankless water heater as this unit only requires there to be a 20 degree farenheight differentiation between water to be heated and heated water. Therfor your shower will at the very least be 100 degrees farenheight which is plenty warm enough.
These co-heating water heating systems are quite complicated so its important that you talk to a prefessional regarding any plans that you have for your home or cottage. Feel free to send us an email if you have any questions.
Which Tankless System Is The Most Efficient?
Jan 8th
Tankless Efficiency Ratings
|
All current tankless units have different efficiency ratings. They can range anywhere from 60 to an amazing 
98 percent. This can of course come with some positives and Negatives. The highest rated efficiency of a tankless system is called the Navien which is 98% efficient. Since the unit uses the heat so effectively it can actually be vented with plastic pipe as the exhaust gases are at a very low temperatures. This unit is one of the first to utilize a condensing heat exchanger giving the unit its amazing efficiency rating.
It has been approved by CSA and thus can be used and sold in Canada and Ontario, which it has been for more than a year now. Before you settle on this unit there are some negatives of this hot water heater. This system has the highest failure rate of all other systems, motherboards are constantly failing causing no heat situations for customers. There has also been been reported a failure with a rubber gas hose off the valve which needs to be replaced. This in turn could possible remove the Ontario TSSA approval and the Canadian wide CSA stamp. 2009 should be an interesting year for Navien.
Currently the best tankless system is the Rinnai it doesn’t have the greatest efficiency rating but it still stands at 84%. If efficiency was a test and that was your mark you would be bringing home an A and that’s something I wish I received more often.
