The Cold water Sandwich
Mar 23rd
What is the cold water sandwich?
|
This sandwich happens when there is warm water for a few minutes then a burst of cold and then rapidly back to warm. This occurs in homes with tankless water heaters as the residual water in the pipes going to a faucet or shower can still be hot. The user in the household will then turn the tap on and feel warm water almost instantly. A tankless water heater takes a few seconds to heat up the heat exchanger and start 
transferring that heat to the water. The result is that a small amount of cold water can make it through the heat exchanger without warming up. When this cold water reaches the end user it may not even be noticed or if the person is in the shower it may be quite evident. After a second or two the heat exchanger is working and hot water is being produced and sent though the hot water pipes bring the desired water temperature again. This does occur more frequently in electric tankless water heaters over gas powered tankless systems. Gas is at full temperature almost immediately where an electric element can take a minute to fully reach its operating temperature.
Now you know what a hot water sandwich is in reference to plumbing and tankless hot water heaters, ask your contractor or installer as there are ways to mitigate this sandwich.

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.
Electric VS Gas Tankless
Dec 5th
Gas VS Electric Tankless |
|
| Gas Tankless Water Heaters | Electric Tankless Water Heaters |
 |
 |
| LP or Natural Gas Prices Significantly Lower | Operating Cost Tends To Be Higher Long Term |
| More Powerful…Continuous Hot Water On Demand | Less Hot Water Due To Amount Of Electrical Current Needed to Produce Significant Amounts Of Hot Water |
| Low Amperage Needed For Operation | Needs at Least 120 Amps to Operate Which Is 5 Times That of a Typical Central Air Conditioning Systems |
| Note: The Comparison Made Between Gas & Electric is Based on several factors. Electic Tankless Water Heaters Can Be Used Efficiently In A One Family Home and Become Competitive To Gas Tankless Heaters.It should also be noted that electric Tankless Systems are IDEAL for cottages and Ontario has a huge vacation property industry. | |
