Tankless Systems in Toronto Winter
Jan 13th
Problems can arise with a tankless water heater in a Toronto winter as the high efficient models (condensing tankless systems) emit a lot of moisture in their exhaust. When the temperature is extremely cold this moisture can freeze and start to plug up the exhaust vent causing your tankless to shut down. Its important to periodically take a quick look at the exhaust vent of your tankless (and furnace/dryer for that matter) just to make sure there isn’t any buildup.
Tankless Issue
- Ice buildup in exhaust vent
- Buildup blocks flow and potentially causes a dangerous carbon monoxide flow into your home
- Tankless should shut down and produce an error code when the exhaust is blocked
Resolution
- If the tankless was just running the warm exhaust gasses should have melted the buildup enough for you to pull it free.
- A blow dryer can work wonders at melting the buildup, but be cautious as the dripping water and electricity can be very dangerous
- Call a service technician if all else fails
This condition is rare and can occur with your dryer or furnace so its important that you as a home owner in Toronto experiencing winter are aware of it.
Noritz NRC111
Nov 9th
The Noritz NRC111 is a condensing tankless water heater. This is the only condensing tankless that Noritz makes and it produces 11.1 gallons of hot water per minute.
The Noritz NRC111 utilizes a dual heat exchanger, which is made from a fusion of stainless steel and copper exchangers. The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger. This results in dramatic reduction of carbon dioxide and increases the tankless heater’s efficiency level to over 93%! Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting. A PVC adapter is built into the Noritz heater for easy installation.

Microwave Tankless Water Heaters….

Microwave Tankless

Giant microwaves to heat water instantly? Is this real? And can it actually work?
A microwave (like in a microwave oven) is generated by a magnetron at a frequency of 2.45 gigahertz, this is the 
exact frequency that targets water molecules and gets them vibrating faster and faster, thus heating up.
The principal behind a microwave tankless water heater is basically the same as your microwave oven at home just on a larger scale. Cold water will simply pass through the unit where it will be bombarded by microwaves actively exciting the molecules to the required temperature. The warm or hot water will then pass through the pluming system to the source of demand.
Effectively this is making hot water produced by electricity actually a reality. There are electric tankless water heaters, sure, but they require massive amounts of power and don’t reliably produce enough water to supply a modern home. Wanderport, a manufacturer of these systems is claiming upwards of 6-7 gallons per minute which is directly on par with conventional tankless systems.
What’s potentially so great about these systems?
First off there is no venting needed, no holes in the walls, no venting proximity restrictions; these are huge barriers that gas or propane tankless systems face. On that same note, the conventional tankless systems sometimes require home owners to upgrade supply lines as units can consume upwards of 199,000 Btu’s.
Secondly a microwave unit has an efficiency of 99% and emits no pollution. The unit also doesn’t degrade over time as a conventional tankless does with calcium deposits and buildups in the various heat exchangers that they need.
So what’s the chances of you getting a microwave water heater in your home in the near future?
According to Wanderport, quite realistic. In fact they have a product on the verge of being released. Its already won an advanced technology award from the
Toronto Construction Association.

T-K3 – $1495.00
|
The T-K3 model, also known as the “Revolutionary T-K3,” is one of Takagi’s most versatile and powerful residential units. The T-K3 offers Easy-Link capability, which allows you to connect up to four units without the use of a controller unit. The T-K3 can also be converted to a direct vent model.
Compact Size:
Only 13.8 inches wide, the T-K3 can be recessed between wall studs for even more space savings! A special recess box is available for outdoor installations.
Lower Activating Flow Rate:
The T-K3 activates at only 0.5 GPM, which allows the use of smaller water flows in bathroom sinks and showers. This reduces water waste and allows for stable temperatures.
Parallel Installation:
Using Takagi’s Easy Link technology, the T-K3 can be installed in parallel with up to three other units without the use of an additional control box, generating more flow while saving money, space and installation time. Four T-K3 unites will deliver a total of 21.6 GPM at 60 degrees F delta T; or 26 GPM at a 50 degree F delta T.
Direct-Vent Conversion:
The T-K3 can be easily converted into a direct vent model for inside installations that need to import combustion air from outside.
Eight Temperature Settings:
Instead of the usual four settings, the T-K3 offers eight separate temperatures, set by dip-switch: 104 degree F, 113 degree F, 122 degree F, 131 degree F, 140 degree F, 158 degree F, 176 degree F, and 185 degree F. This versatility reduces the need for a separate remote control. However, setting temperatures other than the eight presets requires the TM-RE10 temperature controller.
Longer vent runs:
The T-K3 can have a vent pipe run up to 50 feet with five elbows, instead of the normal 35 with three elbows.
As you can see, the T-K3 incorporates all those “why-don’t-you-have-this?” features into this one new product. Its larger flow capacity through parallel connections will meet the hot-water needs of most high-volume residential applications and many commercial projects, too. In short, the T-K3 fills the gap between the single residential heater and multiple commercial T-M1 units. Performance depends on the temperature of the ground water of course: At a delta T of 60 degrees F in warmer areas – for example, where the winter ground water is 60 degrees F and with the output set at 122 degrees F – the T-K3 will provide a 5.4 GPM, or 324 GPH. In colder areas where the input temperature may be 40 degrees F or less, expect a flow rate about 4.1 GPM, or 246 GPH.
