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.

Tankless Issues – The Facts and the Fiction

Some people are very resistant to change, I don’t know what it is but some will fight it until the end of time. A recent Toronto HVAC company posted a large article on their website outlining all the negative aspects of a tankless system and how they would never recommend it nor install one. We install both systems and you know what, they both have their positives and negatives. I hope to detail the issues a little further here and let you decide which system you want for your home.
There is no big savings – This is very subjective, here are the facts.

Tankless

• A tankless will cost you more money upfront than a conventional tank system. True.
• A tankless will last longer -20 plus years.
• Unit and Installation costs are more expensive. True.
• Efficiency of a tankless remains at or just below initial claims for lifespan.
• Much higher efficiency, 82% regular tankless, 98% condensing tankless.
• A tankless does require cleaning to maintain such high efficiency (vinegar rinse).
• Tankless systems do need and use electricity.
• $375 Government grant available for new tankless.

Conventional Tank Water Heater

• Conventional tanks loose 2-3% efficiency per year (scale build-up)
• Cheaper to purchase and install
• Conventional tank lifespan – 12 plus years
• Some tank systems need zero electricity
• Conventional tank heaters start at between 58% and 68% efficiency

Which system is better on your pocket book? It’s going to be up to you as there is a number of factors, including the price of natural gas, which will likely only rise over time.

Upfront costs are high - Yes, it will cost you more for a tankless than a conventional tank, your homes particular usage will significantly affect a breakeven point and whether a tankless is a good idea or if you should stick with a conventional tank system.

High Tankless Maintenance Costs – Your conventional tank has basically zero maintenance barring anything breaks but it loses 2-3 percent efficiency a year. You can flush a conventional tank and regain some of its efficiency with the removal of scale build-up. A tankless is usually flushed once every year or two, which consists of simply pumping vinegar through the system for 30 minutes or so. All tankless systems should have flush valves already installed and this will maintain the extremely high efficiency ratings. I wouldn’t say that a tankless has higher maintenance costs, its just that no one does it for a conventional tank.

Electricity Use - A tankless does need electricity to run sensors, a vent fan, and a starter, this is true. Some tank type water heaters need zero electricity, but if you have a power vented conventional tank system your water heater is using just as much electricity as a tankless would.

The fact of the matter is that a home really needs to be analyzed to see whether a tankless makes sense or if the home owner would continue to benefit from a conventional tank water heater. I won’t make claims on how much can or can’t be saved because any number would be a wild generalizations and any company that does, shouldn’t be trusted.

The 3 primary Navien models

NR-180

NR-210

NR-240

These three are Natural gas systems, but you should note that they come in propane versions as well.  In fact as propane burns hotter than natural gas the propane versions are a bit more efficient.

Navien tankless water heaters utilizes dual stainless steel heat exchangers, providing a longer life-expectancy and more resistance to erosion than copper heat exchangers. All tankless systems are designed to be cleaned and de-scaled, improving life span and durability.

Hot Water Flow Chart.

This chart shows the corrected values for hotwater production of each Navien water heater in relation to ground water temperature.  Here in Ontario, Toronto, Mississauga, Hamilton, and the surrounding cities we should assume a ground water temperature of 35F.

 Intelligent Remote Control For the Navien Tankless

NR-10DU (Included with every Navien Tankless Water Heater)
. Temperature adjustment in 1¡ÆF increments between 98-120¡ÆF
. Touch activated backlight function
. Easy-to-Use button type control
. Built-in recirculation timer for water and energy savings
. Key-pad lock button prevents inadvertent temperature changes
. Advanced water heater diagnosis capability and error feedback

 Endless Hot Water Supply

Navien’s (and all tankless systems) offer an unlimited supply of hot water to meet a home’s unending demand
for hot water. With body showeres becoming much more common place now, it is imperative that you install a tankless.  These new shower systems can
run a conventional tank type water heater dry in very short period.

Navien Venting Benefits

The high effciency of Navien’s Condensing Tankless Water Heater results in lower exhaust
temperatures, allowing for the use of 3” PVC venting.
• PVC venting offers a significant cost savings when compared with other venting materials.
• PVC venting is lightweight and easily slides together, reducing installation time
and makes it easy to run long distances.

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.
