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.

Solar and a Tankless

Solar And A Tankless Heater
|
There is starting to become a buzz around solar hot water systems. If you have a good, knowledgeable contractor a solar water system can work quite well with a tankless hot water heater. 
Here are a few of the advantages that you can expect when combining the two systems.
1. The preheated water coming from the solar water heating system will increase the flow of hot water out of a tankless unit. The reason is due to the fact the tankless has to heat pre-warmed water reducing the necessary temperature rise. The amount of hot water a tankless can provide depends on the input temperature. The greater the temperature rise necessary the slower the water can travel through the heat exchanger and the slower the output flow. Incoming water at 45F vs. 70F vs. 100F will have very different results on the output of a tankless system.
2. The water is already warm or even hot from the solar rays before entering the tankless unit and therefore the added wait time associated with a tankless unit can be reduced or even eliminated.

3. Its important when combining a tankless and solar water heater to consider a tankless unit that recognizes incoming temperature as well as outgoing and is able to fully modulate its burner (therefore only burning the necessary amount of gas to raise the temperature to the appropriate amount).
4. With the right tankless unit and an appropriately sized solar system you may find that your tankless rarely need to run. In fact some people have found that their gas bills are now costing only a few dollars as opposed to a few hundred dollars.
These Solar systems can be a little tricky in Ontario and Toronto as we have winter and the solar system (if it fails) could experience freezing. This would rupture the thermal cells in the collector rendering it ineffective. It may be necessary to use a glycol system to prevent freezing if electricity goes out. Your contractor should be able to provide all necessary info, or fill out the contact form and we can help.

Rheem Tankless water heaters
Follow this company back and it is basically leads you to the founder of the modern day water heater “Edwin Ruud”. There is definitely a lot of history here and the company has several locations throughout the world. Rheem is the largest manufacturer of water heating units in North America. Rheem has a number of residential tankless hot water units to suit the various home water demands
Rheem RTG2-42
This system is rated at 4.2 gallons with a 45 degree Fahrenheit temperature rise, it would best suited for smaller applications. Rheem suggests that this tankless be installed in homes with only one bathroom.

Rheem RTG-53 Series
There are 3 tankless systems in the 53 series but they’re all able to provide the same amount of hot water. Should you have a 45 Fahrenheit temperature rise this tankless would provide 5.3 gallons of hot water per minute. The difference in the three systems is the way they are vented; indoor direct vent, outdoor, and indoor power vent.

Rheem RTG-66 Series
There are 2 tankless systems in the 66 series, you can select either an outdoor model or the indoor direct vent. This tankless hot water heater is able to provide 6.6 gallons per minute at the standard 45 degree Fahrenheit temperature rise. This a new tankless series introduced by Rheem, they recommend these units for 2-3 bathroom homes.

Notes
All of the aforementioned models can be equipped with up to 3 remote temperature controllers enabling you to change water temperature from any room.
These units are also expandable; Rheem offers what they call an easy link cable enabling two units to be connected together doubling the amount of hot water produced.
Rheem also has several commercial Tankless water heaters but that’s for another post.

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.

Navien UPDATE-2010
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).

If your interested in a Navien tankless water heater fill out the form below and we will contact you, there’s no obligation and at the very least you will be more informed on whether a tankless is right for you or not.
Navien UPDATE – Feb 2012
Navien has spent a lot of time reworking their tankless water heaters and removing all the bugs and issues that have plagued them in the past. I feel more than confident in 2012 to recommend their new tankless water heaters.

Tankless Purchasing Guide

Guide For Tankless Purchase
|
Did you know that in your home you are probably paying $60.00 or more per month to simply maintain the heat in a conventional tank type heater? How is this possible? Its simple, your regular tank loses its heat up the flue, or out the chimney, then when the water cools it reheats, and send more money and heat out the chimney. This is occurring even while you’re sleeping or at work.
You likely use most of your hot water in the evenings and morning, do you ever run out? Tankless water heaters are able to overcome these problems. A tankless never runs out of water and can have efficiencies in the high 90’s, you will never run out of hot water in your shower with a tankless.
All of the Earths resources are finite and thus as supplies become scarcer prices will continue to increase, minimizing your consumption reduces your bills. A tankless uses energy only when you ask it to provide hot water, a conventional take keeps water hot even when you’re not there, costing you money. Tankless water heaters will save you more money over their lifespan (20 plus years) than it will cost for the new unit. Plus a Tankless water heater takes up limited amounts of space, is easy to clean, and is easily operated.
Tankless Brand and Venting. With all the different brands available to consumers there is a plethora of venting options to vent the various units. Some tankless water heaters can be vented horizontally and others can vent vertically. The majority of tankless water heaters also have computerized safety devices to protect consumers. Most conventional tanks don’t have these advanced safety features.
Applications and Uses. Some applications of tankless water heaters are: boats, mobile homes, RV’s, and radiant heating systems.
Return on investment. The payback period for tankless water heater is between 3 to 7 years, this is dependent on both energy cost and personal use. If you are a high hot water consumer it will speed up the payback process, if you normally use very little hot water then the payback takes a little longer. Remember though, tankless hot water heaters experience zero standby heat loss and this are much more efficient than conventional tanks.
Energy Audits. Currently the Ontario Government has an incentive program that promotes home energy efficiency. It starts with a home energy audit that assesses the current efficiency of your home, after it is completed a report outlining the current state is sent to the home owner. There is an 18 month period for any renovations to take place; once they are completed a follow up audit is preformed to confirm that all retrofits have been accomplished. At this point grants and incentives are sent from the government to the retrofitted home owner to offset some of the costs.Just installing a tankless water heater qualifies you for $500. Check out the Audit page HERE.
Tankless Lifespan. The expected life of a tankless water heater is roughly 20 years. We have customers who still have their tankless water heaters and it has been in service for more than 20 years. A major reason for this is that tankless water heaters are serviceable, unlike conventional (disposable) tank type water heaters.

Frequently Asked Questions

A Few FAQ
|
Can a home owner install a tankless hot water heater?
We would not recommend a home owner to install their own tankless hot water heater. Tankless water
heaters have strict venting codes that really need to be installed by a professional H.V.A.C company with certified technicians. Most of these units require direct (through the wall) venting with clearance regulations. Unit efficiency can greatly be decreased by insufficient/improper venting. With on demand gas units, gas piping and water pipes may need to be upgraded as well.
Should I buy my tankless hot water heater, then call an installer?
If you decide to purchase a hot water heater from a source other than your installer, you may be faced with warranty issues. Also, all required parts for a full installation, sufficient venting, pipe upgrading and safeties are not usually included when purchasing a unit. Most installers insist on supplying dealer brand units with their installations. This will benefit you, the homeowner, as installers are specifically trained for the brand they install and if required, there will be no warranty issues with parts under manufacturers’ warranty.
