Bosch vs Rinnai Tankless
|
There has been quite the buzz regarding tankless water heaters lately. Claims of their superior energy savings and efficiency have been touted by every company pushing the units. Yes they do reduce the amount of gas or propane you use but they also provide endless hot water. If you take a 45 minute shower your more than likely using more energy than you would with a conventional tank that simply runs out of hot water after 20. Yet if you are reasonable and shower for the same duration, you have great potential to see some real energy (and money) savings with a tankless water heater.
Now that you know you want a tankless you have two options…
Option 1 – Go to your nearest Home Depot and purchase one from there, then hire a gas fitter and a plumber to install it
or
Option 2 – Look for a professional tankless installer who has the specialty to preform a stand-up job.
Being the person purchasing the system cost will obviously be a factor and I guarantee Home Depot will be the cheapest option (If cost is your only driving force you should click the link and head to Home Depot now).
For those of you that stuck around I will explain why the second choice is probably the best choice.
Firstly if you call around to a few tankless installers you will quickly realize that none of them sell Bosch tankless heaters (Bosch is the only tankless brand Home Depot sells). The reason why these companies don’t offer this brand is due to the fact they offer extended warranties and guarantees. They are on the line for the products they sell and thus they go with quality products they know will stand up and remain reliable.
Enter Rinnai.
Ask these same tankless installation companies if they sell the Rinnai brand tankless water heater and I bet you find that 99% of them do. Rinnai tankless water heaters are built to last and this is why industry professionals install this brand. Lets compare the Bosch and Rinnai tankless models and see some of the differences.
Bosch Aquastar Tankless Water Heater 1600H compared with Rinnai R75LSi Tankless
Bosch Tankless Verses a Rinnai Tankless
| Bosch 1600H | Rinnai R75LSi | |
|---|---|---|
| Tankless Weight | 33 Pounds | 50 Pounds |
| Power Input (NG) | 30,735-117,000 Btu | 15,000-180,000 Btu |
| CSA Certified | Yes | Yes |
| GPM | 0.6 – 3.5 GPM | 0.6 – 7.5 GPM |
| Energy Factor | 0.8 or 80% | 0.82 or 82% |
| Heat Exchanger | Residential Grade | Commercial Grade |
| Cost or Price | $939 + installation and Vent | $2850 or $39.95 rental |
As you can see there are some definite differences, probably the most glaring is the amount of hotwater that can be provided. The Rinnai is able to produce more than twice as much, meaning you won’t run into problems when running more than one appliance or faucet..
Of course this doesn’t take into account all the benefits that you get from a professional install like:
- Proper venting, tankless systems have very specific code requirements
- Correct sizing so that you always have enough hot water
- Additional warranty and workmanship guarantees
- Maintenance guarantees, service plans, and emergency tech service.
Sure any Ontario Home Depot has the cheapest system but I hope I clarified why they’re some much cheaper. Now those of you still left reading option 2 and didn’t click on the Home Depot link you are obviously interested in a tankless. These systems can’t go in every home due to venting issues so we send out a technician to make sure everything will work and what size tankless your home would need. This is a free service, so just fill out the form below and we will call you to schedule a time for someone to come by. Typically only 15-20 minutes.
Technicians are fitting and sizing tankless water heaters in all of the greater Toronto area as well as, Hamilton, Burlington, Oakville, Etobicoke, Mississauga, Rexdale, Richmond Hill, Vaughan, Markham, North York, Scarborough, Im sure I have missed some cities but you get the idea, if in question just send us an email.

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.

If you’re searching for an endless supply of hot water for your home or business, Rinnai tankless water heaters offer you hot water on demand,
so you are not stuck with a fixed and pre-heated supply. You can enjoy hot water when you want it and for as long as you want it, so go ahead and do the dishes, run the washing machine and take a long and luxurious bath at the same time. No more worrying about running out of hot water with a Rinnai tankless water heater.
As a Rinnai tankless owner you will enjoy up to 40% energy savings. These units are highly efficient and only heat the water when it is needed. When the demand ceases, the unit shuts down and uses zero energy-a revolutionary advantage over the big and bulky inefficient conventional tanks heaters.
Purchasing a Rinnai tankless water heater, gets you will a reliable and durable copper heat exchanger with a typical life span of 20 or more years (that is twice as long as the old tank water heater’s life span). In addition, the traditional tank water heat accumulates a buildup of rust and sediments that collect in the tank-where the water you drink and bathe is stored. With the Rinnai tankless heaters, no water is stored, so you only get fresh and clean hot water because the water is heated as it passes through the unit.
Being about the size of a small suitcase, the Rinnai tankless unit can be installed on virtually any wall on the inside or outside of your home. Rinnai offers you a line of controllers that makes it very easy to set the hot water temperatures for multiple locations in your house.
(update)
Rinnai Condensing Tankless
Rinnai has a condensing unit out in the market now. This tankless has an efficiency of around 95% and utilizes two heat exchangers to attain the high efficiency rating. Rinnai has maintained the single exhaust vent or concentric piping. This unit will get you the full $375 in available grant money from the Ontario Government.

Rinnai Concentric Venting

Rinnai Venting
|
Rinnai tankless water heaters use a single tube for their venting, how do they do this? It’s quite a simple process that prevents two holes from being drilled in your wall. As you can see in the picture of the elbow, the vent pipe has two distinct sections. This type of venting piping is called concentric venting.
The tankless concentric vent pipe handles both the incoming supply air as well as ejecting the toxic exhaust gases. This form of tankless venting can save an extra hole in your wall and thus reduced risk of air leakage.
Concentric venting is really quite expensive as the pipe is made from stainless steel. On average you are looking at about 60 dollars per foot plus installation. This is why it important to position a Rinnai tankless water heater as close as possible to its venting termination point.
Solar Water Heater and Tankless Update

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.
