Renting a Tankless System
|
Is a tankless rental the right option?
I hate to get in to this and fuel the recession right now but if money is tight then renting a tankless water heater might be the right thing to do.
A tankless rental works out to be a cheap investment for your home as as the cost for the unit is fixed every
month and the amount of natural gas, propane or even electricity consumed is reduced significantly. On top of that a rental system has the installation cost, and the venting kit built into the rental price. Currently systems are renting from around 35 to 50 dollars per month. The price does vary according to the size of the unit required for the house. If you live in a 4000 sq foot home you will need a larger tankless than a 2000 sq foot duplex. Is renting a tankless the right option for you? This is really up to your financial situation, the cost of outright purchasing a system is between $1500 and $3500, renting might work out more cost effective in many cases.

Which Tankless System Is The Most Efficient?

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.
The Tankless Hot Water Myth
Dec 17th
The Tankless Myth |
We have heard this SO many times that I have to try and explain why its completely just a misunderstanding.
Here is a version of the myth “because the water is heated instantly at the unit you will always have to wait for hot water at your tap” or “you have to run the water for a minute or so to get the hot water so its not really instantly hot”.
For some reason many people seem to think that these tankless systems are able to provide hot water at the tap instantly. We have even heard people claim that tankless hot water heaters are not environmentally friendly because you have to run the water for a period of time before the hot arrives.
Figure one.
From this image you can you can see the flow that water takes from a tankless to a tap. The black bar represents insulation, when no one is using hot water the insulation works to keep the existing water in the pipe hot. Over time this water does get cold, by morning the pipe will contain nothing but room temperature water. When you turn the hot water tap on it has to push all the cold water out of the tap, once its gone then you can get the warm water.
Figure Two.
From this image you can see that hot water needs to take the exact same route that hot water from the tankless must take. Therefor it has to push out all the cold water currently contained in the hot water pipe before the user will get hot water and thus there is really no difference between the two systems. Well one is much more economical and energy efficient then the other.
No one keeps there car running all night so that it hot in the morning why keep water in your house hot 24 hours/day? Tankless water heaters solve this problem, and there is practically no noticeable difference between the systems, well that’s not true there is a numerical one on your gas or electric bill.
Tankless Installation Time
Dec 14th
How Long Will A Tankless Take to Install?
This can be a difficult question to answer as there are a number of factors that need to be taken into account. They range from
- Relocation – Does it make sense to move the tankless closer to hot water demands? does this involve moving the gas lines? Is there a venting issue that requires it moved?
- Size / Mounting - The Tankless is significant smaller then a full sized convential tank, this allows it to be mounted numerous locations.
- Venting – All tankless systems have unique venting requirements this may play a factor in its positioning, get a free evaluation here.
- Type – Do you want a propane, natural gas or electric tankless system? These factors can all play a part in tankless installation times.
The installation crews are scheduled to do 2 tankless installs per day, so most installs rarely go past 4 hours (quite a few have been installed in less than an hour). If you decide to go ahead with the tankless system, be that rental or purchase its a safe bet to allocate 4 hours for the install.
Tankless Rental
Dec 9th
You are probably paying $50.00 or more per month to just maintain the heat in a tank type water heater. WHY? Because the tank system looses its heat up the flue and then reheats, even while you sleep or are at work. This is called standby heat loss. 
The payback period for tankless water heaters is 3 to 7 years depending on how much hot water you use and the cost of energy. The smaller the amount of hot water that you use, the faster the payoff. If you are single and are seldom at home using hot water, your energy bill reflects the low consumption because tankless water heaters do not experience standby heat loss. Rewarding conservation is a key toward protecting future fresh water supplies.
Switching to a tankless water heater is easy. You can rent a Rinnai tankless water heater for about $35 per month. If you live in Anywhere in Toronto, Bramton, Hamilton or all of the GTA, all you need to do is send us your information and we’ll give you a free assessment. You can get started today.
