Renting a Tankless Water Heater
|
For a lot of people in Ontario renting your water heater is something you have always done, the charge is roughly between 10$ and 20$ a month. Companies that provide this service (for the most part) 
put in low end tanks so that their return on investment is only a few years. The problem is that low end tanks are energy hogs and consume copious amount of power. The company you rent it off of doesn’t care about efficiency as they are not paying the bills, thus the problem.
Renting a Tankless Water heater is going to be more expensive on a monthly basis but the savings it 
produces more than outweigh the additional cost. Remember a Tankless water heater is the top of the line water heating system, if it’s a Navien (or Navian which is often spelled incorrectly) you will be getting 98% efficiency. A Rinnai will produce great savings with lots of hot water and very reliable service. These units are the best there is for residential hot water demands.
The rental fees are almost identical from all companies that are offering rental tankless systems in Ontario and the greater Toronto area. On average you will be looking at between 32$ and 40$ per month for the rental water heater. You will also be getting the peace of mind that if anything goes wrong the unit will be replace or fixed.

Navien Tankless Water Tank

Navien Tankless Water Tank

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.

UPDATE
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).

Tankless Facts
|
- 25% of every household energy dollar is spent making domestic hot water. Heating water with a conventional tank is the third largest energy consumer in your home (behind furnace and A/C).
- Electricity is the WORST way to heat hot water while natural gas and propane gas are much more efficient. Based on national fuel price averages of $1.46/ccf and $0.09/kwh, the cost/100,000 BTU’s is $1.46 for natural gas and $2.64 for electricity. Just under 60% of North American households have access to natural gas, and if you don’t, propane gas is available to almost everyone and is still a better value than electricity. In addition electric water heaters have only a small fraction of the capacity of gas water heaters. So if you like expensive, short showers, with cold water at the end, use electric; otherwise gas would be a better choice.
- Modern gas fired tankless water heaters are the best alternative available to today’s homeowners to reduce their residential energy consumption. A typical gas fired tankless water heater cost about 2-1/2 times as much as a standard tank water heater. However it will pay for itself in just a few years or less, and will last twice as long as a tank.
- If you are considering a tankless water heater Rinnai is likely the best choice. On average a new Rinnai is installed somewhere in North America every 3.75 minutes. Rinnai has shipped over 30 million tankless water heaters world wide.
Greatest Tankless Penetration

Most Popular Areas

2008 was a great year with many people switching over to tankless systems, it sure has keep us busy around here. Going over some of the results have yielded some surprising stats.
Most Popular Brand
Rinnai
This was not that surprising to us as we had a hard time maintain an adequate amount of stock for customer installations. Hands down the Rinnai tankless is the best unit out there.
Navian
This units efficiency rating was through the roof and thus made it an easy choice for a lot of consumers, we have stopped selling it due to system flaws. 2009 should be a much better year for the Navien.
Location
Toronto Core
This location has one of the highest densities of homes and so it is to be expected that it had the greatest density of tankless installs.
Mississauga
We didn’t expect this but Mississauga came in second with numerous installs of tankless systems.
Brampton
Brampton came in third for the city with the most tankless installs. They also had the highest penetration of Rinnai’s verses other brands, 94 percent were installed Rinnai’s. That topped all the other cities by a slight margin.
Oakville
There is really nothing too exciting about Oakville but they achieved the fourth highest number of tankless installs.
Markham
This city has achieved a fifth place ranking on total tankless installations but they also have the highest number of rented tankless systems.
Burlington
Not the greatest claim to fame but Burlington had the highest percentage of Navian’s installed, and the city with the sixth greatest tankless installations
Other
We installed tankless systems in many other location, nearly 50% were installed outside the six cities listed above. Here is a list of 9 more make this a list of 15 top tankless installs per city in Ontario.
- Hamilton
- Etobicoke
- Richmond Hill
- Scarborough
- Vaughan
- Kitchener
- Guelph

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.
