Instant or Tankless Water Heaters?
Apr 29th
Things to Know.
|
Most of us have grown up with a standard tank type water heater. As such we are used to the way our hot water system works. Switching to a tankless water heater will have an affect on the way your hot water system works.
With a tank type heater, when you turn on a hot water faucet, the hot water, typically 140 degrees, immediately begins flowing through the pipe to get to your faucet. As the water travels through the cold pi pe, it cools off until the piping material warms up. That is why your hot water doesn’t instantly go from cold to hot; it has to warm up the pipes first.
Some homes have hot water circulating systems that circulate the hot water through the pipes to obtain instant hot water at every sink. Circulating systems can save a lot of water. They are wasteful of energy though, since the water heater will fire up more often to replace the heat being lost through the piping which acts like a big radiator even if the pipes are well insulated.
There are also pumping systems that pump the hot water to the fixture from the heater only when you want to use hot water and you don’t run any water down the drain. You still save the water and time, but you don’t waste water.
Tankless Systems
Tankless water heaters are being promoted as providing endless hot water and as being energy saving over traditional water heaters. While both of these facts are true, there are other things to consider.
If you are considering replacing your tank type water heater with a tankless unit, and you have a typical house, make sure you get one large enough to do the job. Since you are heating water as you use it, you must heat it much more quickly than a tank type heater so you need to add heat much more quickly.
For a gas type heater this means you will be using a lot more gas volume/ minute than with a tank type heater. Your exhaust flue may need to be larger and the gas line might need to be upgraded. For electric units you might have to have special wiring put in to handle the high amperage loads created by an electric tankless water heater.
Tankless water heaters are typically much smaller than conventional tanks and are hung on the wall, resulting in a significant space savings.
Tankless water heaters can save you a modest amount of energy, typically around $20.00 – $40.00 a month. They are also eligible for home energy Grants and Rebates provided by the Government to aid in a speedy transition from the old energy consuming conventional tank to this new efficient technology.
The Best Tankless Water Heater

The best Tankless ?

This is a controversial question as some tankless water heaters result in a much better fit than others and thus they may be considered better by some users on different situations.
We have facilitated the installation of thousands of tankless systems and ensured that additional warranty and extended service is provided on all of the installed systems. In terms or reliability the Rinnai tankless heater is by far ahead of all the competition. Service records are able to prove this statement, emergency maintenance personnel are rarely called to fix the unit.
The Rinnai R75 is one of our biggest sellers.
- 12 year heat exchanger warranty
- Max input of 180,000 BTU
- EZ connect (2 unit connection)
- 7.5 GPM
- Energy factor of 0.82
- Concentric venting
- Reliable
It should be noted that Rinnai has very particular venting requirements that make it a bit more difficult to install. The specialized vent pipe is concentric meaning that the exhaust pipe is inside the intake pipe. This means that the hole drilled in the wall is at minimum 5″ in diameter. What makes it such a great unit is its reliability, Rinnai systems rarely break down.
The Navien tankless is a big seller as well; it has the condensing aspect of the market cornered. This condensing technology brings the efficiency of the unit up into the high 90’s and makes it the most efficient tankless. Do note – There have been issues and we are servicing this tankless more than any other we have installed.
The Navien CR210A is the primary tank installed.
- Max input 175,000 BTU/h
- Energy factor of 0.95
- 7.6 GPM
- Buffer tank and circulation pump
- PVC venting
- Cheap and Reliable (2011 models and newer)
The water quality in Toronto and surrounding areas like Mississauga, Brampton, and Caledon (Peel region) is considered moderately hard. Vaughan, Markham, Richmond Hill, or York Region has hard water due to the Oak ridges moraine and deposits within it. City of Toronto, Pickering, Ajax, and all cities along the shore of Lake Ontario that rely on the lake for water have moderately hard water. This is important to know as a tankless water heater can collect deposits causing the systems efficiency to be reduced. It is important to clean your Tankless water heater on a yearly basis.
There are a number of great tankless water heater brands available in the market place currently. The new version of the Navien condensing tankless seems to have far fewer issues. Also most of the manufactures have developed and now sell condensing units.
Takagi TH-2 is a great condensing tankless
Rinnai has condensing unit available that works amazing as well — RC98 Brochure
Noritz also make a very good condensing tankless.
All of the units mentioned above have very similar stats and performance, thus its boils down to the situation. Get a few quotes and go with an installer that’s not quoting you the bottom of the barrel price, you will get what you pay for. The brand of tankless that you choose will be determined in part by you and the layout of your home with regards to venting and code requirements.

Tankless Systems Installed in Etobicoke
Apr 23rd
Tankless Sytems Etobicoke
|
We have install thousands of tankless water heaters in Toronto and surrounding areas. Etobicoke has proven to be one of those locations where the system will usually go in without a hitch. The water in Etobicoke is well
suited for a tankless system as there is not much buildup or scaling produced by it. Most homes are serviced by natural gas and provided at a reasonable cost to home owners. Venting has proven to be quite easy as homes seem to all meet requirements set out by Canadian Governments and the Tankless manufactures.
Now that the Ontario Government has reactivated the grants that were available to home owners its a great time to send us a message and have someone out to your home and make sure that a tankless water heater can be installed in your home.
If your interested in having a home energy audit done first please go here to book one.
New Tankless Grants in Ontario
Apr 21st
Ontario Tankless Grants
|
Its still early but I think its safe to say that the Ontario Government is maintaining its side of the grant money 
available to home owners. It has been a relatively convoluted situation as some people have received official continuation press releases while others haven’t. Currently we haven’t here at Tankless Water Heaters but today a service provider brought one in for us to view. We will try and have a copy posted up soon.
Grants are back and available to Home owners for tankless water heaters.
If you were kicking yourself for not getting a tankless when the government grants were available then your certainly in luck today.
Does a Tankless Water Heater Save Money?
Apr 7th
Tankless Systems Save
|
Tankless systems are very effective at saving you money. This only makes sense as they only provide hot water on demand. They don’t heat water and then hold it, continually maintaining that temperature.
You wouldn’t leave your car running all night so that it was warm in the morning would you? Well that’s what your hot water tank does day in and day out.
Our tankless water rental tanks have been unaffected by the drop of the government grants. If your living in the greater Toronto area, and place like Brampton, Mississauga, North York, Hamilton, Richmond Hill, Thornhill, and Markham. You are very likely renting your conventional tank and paying upwards of $20-$30 a month for a system worth $700 at most. Upgrading to a tankless and we take care of returning your old tank, and installing a tankless. All for roughly $10 more a month and you have a system valued at nearly $4000 providing your hot water.
- Tankless systems are more reliable
- Tankless water heaters are more energy efficient
- They provide endless hot water
- You get unlimited tech support
- Unlimited emergency service and repairs
These systems are proven energy and money savers, sure they cost a little bit more a month to rent but you easily make that up in the natural gas or electricity reduction savings.

End of Government Grants for Tankless
Apr 4th
Grants End
|
In a surprise announcement on Thursday April 1 2010, the Federal government suspended the Ecoenergy retrofit program. This program aided homeowners in upgrading their existing HVAC equipment to more energy efficient models, thus reducing greenhouse gases that homes emitted substantially. The program was axed due to its popularity, more than 3 times more Canadians participated than the Government had anticipated. Typical government fashion, lets end anything that is actually working and making a change. This puts more than 2000 energy auditors and countless other support staff out of jobs, and that’s only in Ontario.
Can I Still Get An Audit?
Unfortunately, you can not get an audit anymore. There are no more grants available for tankless water heaters from Federal or Provincial governments.
- The Ontario provincial government was matching all grants, this has also ended.
- This isnt the end, there will be incentives from companies and manufactures to try and maintain the low entry cost for a tankless water heater.
- Check back here as we will be following the situation and posting any updates.
I Have Had My D-Audit, Will I Not Get My Grants?
- If you have had your D-Audit but nit your final E-Audit then you are lucky. The Government will still honour all rebates and upgrades that you do. You have until April 1 2011 to perform any upgrades and have your final E-Audit. I would recommend that you look into upgrading as much as you can over the next year, you can get $1500 back on a new furnace and $750 on a tankless water heater, and even more on roof and wall insulation. Your in a good situation, I would definitely take advantage of it.
Is a Tankless Water Heater Even Worth It Now?
- Even though you are not able to get the grants for a tankless water heater the cost to benefit is still greater than having and maintaining you conventional tank water heater.
- Natural Gas and Electricity prices are only on the rise, any system that can cut their use by over 40% will net you savings.
- If you need a loan to purchase a tankless rates are still exceptionally low
- Our rental rates haven’t changed, you can still rent a tankless for $39.95 a month
