Heat Exchanger
Navien tankless water heaters utilizes dual stainless steel heat exchangers, providing 3.8 to 4.5 times longer life-expectancy and erosion resistance over the copper heat exchangers used in other tankless brands. Navien’s heat exchangers operate with relatively low water temperature, minimizing damage from hard water conditions and maintains efficiency levels. Its always important to have your tankless flushed once every 2 years or so to remove any buildup from within the heat exchangers.
Efficiency
Because of Naviens high efficiency the tankless can be vented in PVC piping. Basically excess heat is exhausted with all the combustion gasses in conventional tank systems but a Navien uses this to further heat the water. This results in significantly lower exhaust temperatures and allows for the use of PVC exhaust vent piping.

Takagi T-H2S
Nov 14th
The Takagi T-H2S is a new tankless model that Takagi has developed and is now offering. It is available in either Direct Vent or Outdoor models. Takagi’s T-H2S is a condensing tankless that is
very energy efficient (up to 90% EF). The T-H2S was designed for residential applications and is a candidate for the ECOenergy audit rebate program and its $375 tankless rebate program.
The T-H2S Flow
Seeing as the T-H2S is one of Takagi’s greenest tankless models offering an average efficiency of 90% with natural gas and 90% with propane. If you choose this tankless model here in Ontario, Toronto, Barrie, or any of the surrounding cities expect a flow rate of about 4.1 GPM or 246 GPH with an input temperature at 40ºF or less.
Takagi states that the T-H2S tankless can provide at least two showers worth of water simultaneously in addition to one appliance.
Features
The T-H2S can be vented with PVC providing zero clearance for direct vent installations.
PVC venting can be used in all applications and a 3″ exhaust venting option is coming soon.
The TH2S utilizes dual exchangers to maximize the unit’s energy efficiency.
The primary heat exchanger is made of copper while the secondary is stainless steel.
This secondary heat exchanger is used to recover waste heat from the vent stack to preheat
the incoming ground water. This is in fact what classifies the TH2S as a condensing
tankless water heater.

Solar Hot Water and a Tankless
Oct 31st
To really reduce your hot water heating charges you could look at adding an active solar water heater in conjunction with a tankless water heater. The rays from the sun would pre-heat the incoming water and then the tankless would simply finish the job. It’s difficult to get a solar water heater to produce water hot enough for today’s household demands, but with the technology in a tankless system it’s a perfect fit. 
Tankless water heaters are smart no, they check incoming water temperature and vary their burners to adapt. So if you have relatively hot water coming in to a tankless it will scale down its natural gas injection to ensure that water out temperature is at your set level. If the burner is scaled down so is your gas bill as only a fraction of fuel is needed.
This is a complicated system and it will be costly, if you are doing this to save money you probably won’t see a breakeven point for a long time. If you’re interested and looking at installing a Frankenstein system you are probable doing it for the environment.
What’s required?
If your installing somewhere in the southern states this will be a lot easier as you don’t have to worry about sub-zero temperatures. Up here in Ontario it’s a definite issue and there are a few systems that can be installed. There is the Active Glycol-based system that circulates food grade glycol and transfers the heat via a heat exchanger to the potable water; this is less efficient but the safest and most popular system in Ontario. The other way is though a drain back system, potable water is forced though the solar collector and drains instantly when the water is shut off. Both these systems work to preheat a tankless systems incoming water supply ultimately reducing the heat and gas needed to raise water temperature to the desired warmth.
These dual systems are not very popular due to the increased expense but a tankless is well suited and designed for a hybrid system. If the idea seems interesting but the price too high you should note that they can be installed in stages, tankless first and then the flat plate solar collector.
Periodic Maintenance of a Tankless
Oct 27th
There areonly a few things that need to be maintained on a tankless water heater. If these steps are preformed regularly you can expect your unit to last much longer (20 plus years) than a conventional tank type water heater.
First there is a inline screen filter that is installed to insure that incoming water is clean and free of debris before running through the heat exchanger. This little filter should be checked every so often, (dependent on water quality) and is a circular mesh screen. Incoming water needs to be shut off and then the screen can be cleaned.
Secondly a tankless needs to be flushed to remove calcium and scale build up in the heat exchanger. If your tankless was installed by a reputable company they will have included a pair of flush valves which make this process quite easy. It’s probably best this be done by your installer but here is a brief rundown of what occurs. Water and gas are shut off and the unit is drained. Then two hoses and a small pump are hooked up to the flush valves and fresh vinegar is pumped through the systems heat exchanger for roughly 30 minutes. This cleans out all the buildup and scale that severely reduces a water heaters efficiency.
Those are basically the two things that a tankless owner needs to perform to ensure maximum efficiency and a prolonged lifespan. Barrie through to Toronto and basically all of southern Ontario have significant concentrations of limestone and thus relatively hard water conditions. A conventional tank can’t be cleaned whereas a tankless can and hot water accelerates the rate of scale deposits.
Barrie Tankless
Oct 27th
Barrie draws all its water from wells located stategically around the city. This has a few benefits for homeowners looking to switch over to a tankless system, firstly its warmer in the winter than it would be if drawn from Lake Simcoe and thus uses less energy to heat up. Secondly the water is purer and has less dissolved mineral content reducing the buildup of scale in a tankless heat exchanger. Thus if your a Barrie resident a tankless is a good system to invest in.
We can service and install tankless systems in a number of areas in and around the Barrie area (Essa, Bradford, Nottawasaga, Innisfil, Alliston, Stayner, Keswick, Wassaga, etc). It never hurts to ask, so if you’re at all interested Get More Information Now
Tankless system provide instant hot water and can provide an endless supply, they can reduce water heating bills by up to 50 percent, and have a significantly loger lifespan than a conventioanl tank type water heater.
Don’t forget Barrie and the Province of Ontario are still offering grants and rebates to home owners who make the switch over to a tankless system. So if you live in Barrie or area you can get a Government rebate with an energy audit to help offset the additional cost.

Debunking Some Common Tanklesss Beliefs
Oct 18th
I have read a few articles lately regarding a number of beliefs, ideas, and thoughts on the benefits and opinions of tankless water heaters. I would like to take a few minutes here to verify and nullify some of them.
A tankless water heater will not save you money.
This depends so much on the situation it’s impossible to make any claim that a tankless will not save you money. Here are a few variables that factor in.
- The price of natural gas varies by Province, City, Country, and even supplier and on top of that there is delivery charges, taxes, and additional fees. A tankless can significantly influence these costs instigating either an increase or a decrease (more often than not its a decrease).
- The price of the tankless… this varies again with the size of unit, the brand etc etc. Also be careful of door to door conventional tank type water heater sales people, more often than not those contracts are much higher than the actual cost of a tankless.
- Tankless warranties are pretty similar to a conventional tank type water heater, but…. a tankless is designed to be serviced and have a lifespan of over 20 years. Their heat exchangers are designed to be cleaned of all calcification, whereas you tank type heater is simply designed to be replaced
So take the what you hear about the advantages and disadvantages of a tankless with a grain of salt. If someone has decided it’s not for them and feels it important to rhyme off a few common misconceptions take the time to investigate and see if its right for your home.
Tankless Flushing Service
Dec 10th
We have been receiving numerous requests for tankless cleaning, help, and advice, so in response we’re starting a new service…. Tankless Flushing! Thousands of tankless water heaters have been installed in Toronto and surrounding areas with sales people promoting a lifespan of 20-25 years….. Sure a tankless can last a long time, but not without some regular maintenance. Right? RIGHT!
First and most important, de-scaling your tankless water heater.
If the installer was good you will likely have isolation or flush valves installed. These valves allow you to push vinegar or a scale removal agent through the tankless effectively cleaning the buildup off the wall of the inside of the heat exchanger. As we wrote in “Lime Scale The Energy Thief” it really doesn’t take much buildup to decrease efficiency significantly (and isn’t that what you bought the tankless for in the first place?).
The Process
At the Tankless Hot Water Guide were here to help people first and foremost, if you are hand this is something that you can do yourself. Here are a brief outline of the steps necessary to flush your tankless heater.
- Unplug your tankless.
- On the blue isolation (flush) valve shut the Cold water supply off.
- On the red isolation (flush) valve shut the hot water exit off.
- Now you will need two short hoses, a bucket and a pump of some sort.
- Attache the two hoses to the isolation valves (flush valves).
- Attach the other end of the hose running from the blue isolation valves to your pump.
- Fill the bucket with your de-scaling agent (vinegar).
- Turn the pump on and make sure that the red isolation valve hose is running back into the bucket.
- Let this run for at least 30 minutes.
- –If the system hasn’t been flushed in a long time and you see a lot of grime, unplug the pump, dump and refill the bucket with new vinegar. Let run for an additional 30 minutes.
- After you are finished dump the bucket and fill with clean water, start the pumping again to flush the vinegar out of the system. If you use a chemical de-scaling solution make sure to rinse your tankless thoroughly.
- Almost done!
- Disconnect all the hoses, replace caps, double check everything is back to normal.
- Turn the two valves back to the on or flow position and plug the tankless back in.
- Run the hot water at a few taps to push any air in the system out and confirm hot water is being produced.
- Repeat once every year or so.
