Takagi Condensing Tankless Review
Mar 16th
Takagi Condensing Tankless
|
Here is the Takagi T-H2 Condensing Tankless hot water heater, there’s a lot to cover so lets get started.
Takagi Tankless Benefits
- PVC venting
- 95% efficient
- 4.6 GPM in dead of winter
- 8.5 GPM in the summer
- Direct vent capability
Info
The T-H2 model is available as a direct vent or an Outdoor model only. Takagi’s T-H2 “2nd Generation High Efficiency Tankless” unit, is a very energy efficient tankless unit (up to 95% in thermal efficiency) in the Tankless industry. The T-H2 was apparently designed for residential and light commercial use and offers Takagi’s Easy-Link to join multiple units.
The T-H2 can provide upwards of three showers’ worth of water simultaneously in colder climates.
The T-H2 can be vented with PVC, providing 0 clearance for DV installations. PVC venting can be used in all applications and apparently Takagi says that 3″ exhaust venting is now available (previously it required a 3″ intake and a 4″ exhaust).
The primary heat exchanger is made of “Heat Resistant Alloy” HRS35 Copper, Takagi has also added a “High Corrosion Resistant Stainless Steel” #316L secondary heat exchanger to recover waste heat from the vent stack before it leaves the unit to preheat the incoming ground water. This second heat exchanger and the resulting condensation that forms from the high efficiency operation, classify it as a “Condensing” Water Heater.

As we all know Canada can has winter, and this affects our ground water temperature. The higher the tankless has to heat ground water up the lower the output flow of hot water is. Ontario’s ground water fluctuates with the coldest temperatures occurring in February and the warmest is September. Toronto, Hamilton, Brampton, Scarborough, Mississauga for example are places that rarely see ground water temperatures dip below 40 degrees Fahrenheit. Thus its safe to assume a minimum of 4.6GPM in the worst of conditions.

How Loud Is A Tankless Water Heater
Jul 7th
Tankless Sounds
|
We have had a number of inquiries about how loud a tankless water heater is, how it compares to conventional water heaters and what appliance would it be on par with. 
First, tankless water heaters have basically a blower motor and a burner, nothing else would really make any noise. A power vented conventional tank water heater would have exactly the same components. We asked a few of our customers how they felt the noise level was and they all said that they didn’t notice a difference.
As mentioned above if your old tank was power vented its very unlikely that a tankless is any louder than the system 
you had. If it was not power vented than the tankless would be a bit more noticeable in terms of volume.
I would say in my opinion that a tankless would maybe be about as loud as a computer fan or maybe an electric can opener. Somewhere along that lines.

GE Hybrid Electric Water Heater

GE Hybrid Electric Water Heater

Heating water for showers, laundry, dishwashers and other household needs can account for up to 25 percent of a home’s total energy cost. General Electric hopes that they figured out a way to persuade
homeowners to upgrade from a conventional electric storage-tank water heater to its new heat-pump water heater, expected out in the fourth quarter of 2009. A heat-pump water heater is quite common in Japan, but GE’s 50-gallon Hybrid Electric Water Heater represents the only U.S. version from a major manufacturer. This is an electric conventional style tank that holds between 40 and 60 gallons.
This heat-pump technology being used works be allowing heat to transfer from the air to the water stored in the insulated tank. (The conventional style tank will also retain some traditional electrical heating elements, which will kick in when needed.) GE claims this new water heater will use 2,300 kilowatt hours annually, about half that of a standard electric water heater. Those savings could help defray its cost, which at $1,200 to $1,500 American is higher than purchasing a conventional tank.
Realistically if you have gas or propane service at your home it would be much more efficient and cost effective to go with the new tankless water heaters that are available. Additionally since the unit is absorbing heat from the surrounding air it has to give off cool air which in Toronto and surrounding area means that your furnace will have to then work to heat that new cool air.
This may be an interesting product for any cottages or homes with electrical service only.

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. | |
