Storage Tank vs. Navien Tankless Water Heater: What’s the Ideal Water Heater for Your Home
Whether you’re remodeling your home or you’re building your first home, your choice of water heater greatly impacts you and your family. Since 19% of the energy used in the average Canadian home goes to water heaters, your decision on what type of water heater to buy will have a lasting impact on your family’s finances, as well as the quality of life for your family.
What Is a Storage Water Heater & How Does It Work
A storage water heater is a big, cylindrical tank with pipes attached to it. It has 2 functions: it heats water and stores water until its needed.
A storage water heater that is meant for a single family offers a standby supply of 75 to 302 liters of hot water. When you turn on the hot water tap, hot water is released from the top of the storage tank. To replenish the hot water, cold water enters at the bottom of the storage tank.
In order for the water inside of the storage tank to remain warm, the water is constantly being heated even though there isn’t a hot water tap turned on. This constant heating of the water in the storage tank, called “standby heat loss”, wastes energy.
In order to extend the life of the storage tank and to lessen the loss of efficiency of this type of water heater, the following periodic water heater upkeeps are required:
- Flush a quart of water from the storage tank every 3 months.
- Check the pressure valve and temperature every 6 months.
As a safety measure, all storage water heaters are fitted with temperature-and-pressure relief valve. In the even that either the pressure or temperature goes beyond a safe limit, this valve opens.
- Inspect the anode rod every 3 to 4 years.
All storage water heaters have an anode rod. The purpose of this rod is to control corrosion – the primary reason to storage tank fails. The rod is specifically designed to corrode. As such, it’s important to inspect the anode rod every 3 to 4 years and replace it when necessary.
What Is a Navien Tankless Water Heater & How It Works
A Navien tankless water heater is a specific type of tankless water heater that offers a continuous flow of hot water, without the large, cylindrical tank.
Navien tankless water heaters, specifically the Navien NPE tankless water heater series, can be mounted on the wall and occupy 80% less space in comparison to the 302 liter storage-type water heater. The biggest model of the Navien NPE tankless water heater series is only 17.3”W x 27.4”H x 13.2”D.
The Navien tankless water heater don’t waste energy as the storage-type water heaters do. Tankless water heaters only heat water when it is in use; therefore, there’s no cost for maintaining heat.
According to the U.S. Department of Energy (DOE), for a household that uses 155 liters or less of hot water every day, a tankless water heater can be 24% to 34% more energy efficient than a storage-type water heater tank. The U.S. DOE added that a tankless water heater can be 8% to 14% more energy efficient for a household that uses a lot of hot water – approximately 325 liters each day.
According to Natural Resources Canada, a typical Canadian household uses an average of 75 liters of hot water every day for showering, cleaning, washing dishes and clothing.
ENERGY STAR estimates that the average family can save up to $100 or more each year with an ENERGY STAR qualified tankless water heater; the Navien tankless water heater is an ENERGY STAR tankless water heater.
The purchase price of the Navien tankless water heater can be higher than the storage-type water heater; however the long life span, low operating costs and low energy costs can offset the initial rate.
The Navien tankless water heater has parts that ensure years of trouble-free service. The heat exchanger in the Navien is made of stainless steel, not copper, extending the life of the heater by resisting corrosion. It also has the industry’s longest warranty, including 15 years on the heat exchanger.
The operating cost of a 189 gallon storage-type water heater (based on the annual estimated residential use per U.S. DOE test criteria) is $293 and other tankless water heater brands are $228, while the Navien tankless water heater’s annual operating cost is only $191. Depending on your location, you can also avail for a variety of energy efficiency credits and rebates.
“It’s important to remember the cost of energy to operate a product over its lifetime is just as important as its purchase price. For water heaters, the operating costs are calculated by factoring in the size and type of unit, the energy source, and the equipment’s energy efficiency,” Natural Resources Canada said.

Why Choose a Navien Tankless Water Heater?
You don’t normally think about your water heater – not until you run out of water or your water runs cold.
According to Natural Resources Canada, an average Canadian home uses 75 litres of hot water every day for bathing, cleaning, washing clothes and dishes. Water heaters account for 19% of the energy used in the average Canadian household. It is the second largest portion of the energy utility bill after space heating.
More and more environmentally-friendly, internet-connected, budget conscious and convenience conscious homeowners are turning to Navien tankless water heaters.
What is a Tankless Water Heater?
A tankless water heater, also known as an instantaneous or on-demand water heater, provides hot water only when it is needed. A tankless water heater is just one type; the other types of water heaters include storage tanks, heat pumps and solar domestic hot water systems. These different types of water heaters can be powered by either oil, gas, propane or by electricity.
How a Navien Tankless Water Heater Works
The Navien tankless water heater is powered by natural gas and it works in the following manner:
Step 1: When a water tap opens, the Navien tankless water heater detects the flow.
Step 2: The unit’s flow sensor activates to establish the amount of hot water needed.
Step 3: The igniter activates.
Step 4: The gas control valve opens to supply the right amount of gas.
Step 5: The fan and venturi activate to provide the right amount of gas and fuel.
Step 6: The premix burner ignites, providing a flame to heat the water.
Step 7: The tap water begins to pre-heat in the secondary heat exchanger.
Step 8: The pre-heated water moves to the primary heat exchanger from the secondary.
Step 9: The Navien tankless water heater determines outgoing set temperature and adjusts the flame that heats the water.
Step 10: The heated water moves to the buffer tank.
Step 11: The desired hot water amount is then delivered to the faucet.
Top 5 Reasons for Choosing the Navien Tankless Water Heater
Here are the top 5 reasons for choosing this water heater:
- Saves Money
When purchasing a water heater, two price tags have to be considered: the purchase price and the operating cost. What good is a cheap, brand new water heater if the long-term operation cost can ruin your family’s regular budget?
“Every energy-using appliance has two price tags” according to Natural Resources of Canada. “We know the first – the purchase price. The second price tag is considered less in the purchasing decision, but is just as real; it is the operating cost of the appliance. The purchase price is like a down payment. You can think of the second price – the cost of operation – as a series of monthly payments that last as long as the appliance operates.”
Based on the annual estimated residential use per the US Department of Energy (DOE) test criteria of $1.09 per therm of natural gas, the annual operating cost of a Navien tankless is $191; the annual operating cost of other tankless water heaters is $228 and $293 for a 50-gallon tank water heater.

7 Facts about Navien Tankless Water Heater
If you’ve run out of hot water or your water heater simply stops working,
then you understand the importance of choosing the right water heater for
For your next water heater, here are 7 facts about Navien tankless water
heater for you to consider:
1. It provides hot water only when it’s needed.
Navien tankless water heater is a type of water heating system that
provides hot water only when you need it. The traditional tank-type water
heaters, on the other hand, produce hot water 24/7 – even in instances when
it isn’t needed. Tankless water heater is also called demand-type or
instantaneous water heater.
By heating your water only when it’s needed, your Navien tankless water
heater doesn’t produce the unnecessary standby energy associated with the
storage type water heating system. This by-demand water heater saves you
2. It delivers quick and endless water.
Navien’s “ComfortFlow” technology delivers you fast and continuous flow of
hot water. No more cold showers. No more running out of hot water and no
more waiting time for the water to heat up. A tankless water heater heats
water without the need of a storage tank. When you turn on your hot water
tap, a gas burner is fired up and heats the water. Because of this, a
tankless heater delivers instant and constant supply of hot water.
The company’s ComfortFlow technology eliminates the “cold water sandwich” –
a phenomenon associated with other conventional tankless systems where the
water that comes out of the heater for the first few minutes is warm,
followed by cold water and then followed by warm water.
3. It saves money.
According to Natural Resources Canada, every day, Canadians use an average of 75 liters of hot water each at
home. Hot water is typically used for washing dishes and clothing,
showering and cleaning. Based on the 2013 report of the Natural Resources
Canada, space heating accounted for 63% of the energy used in the average
Canadian household, followed by water heating (19%), appliances (12%),
Lighting (4%) and space cooling (1%).
“Make the switch to an ENERGY STAR certified water heater to cut your
electricity bill and reduce your carbon footprint,” the Natural Resources
A. Energy Factor
Navien’s NPE-A series received a 0.97 energy factor from ENERGY STAR – an
international program that provides certification for consumer products
which meet certain standards of energy efficiency.
Energy.gov, which is run by the US Energy Department, defines energy factor as “the amount of hot water produced per unit of fuel consumed over a typical day”. According to the department, the higher the energy factor, the more efficient the water heater is.
B. Operating Cost
A high energy factor, however, doesn’t equate to lower annual operating
cost, the department said. In calculating the annual operating cost, the
following elements have to be considered: energy factor and fuel cost. The
estimated annual operating cost of the Navien tankless water heater, based
on the annual estimated residential use per US Energy Department test
criteria, is $191.
This $191 estimated annual operating cost is lower compared to the
estimated annual cost of a 50-gallon tank-type water heater, which is $293.
That’s a saving of more than $100 per year.
C. Product Lifespan
For its heating system, Navien used stainless steel heat exchangers instead
of copper – a metal that’s susceptible to corrosion. Stainless steel, on
the other, is corrosion resistant, extending the lifespan of the Navien
heating system. According to Energy.gov, most tankless water heaters have a life expectancy of over 20 years. In contrast, tank-type water heaters last for 10 to 15 years.
Navien offers the strongest warranty in the industry, including the 15-year
warranty on the heat exchanger. Energy efficiency credits and rebates are
also available depending on your location if you purchase a Navien water
If you calculate your yearly savings, added lifespan, credits and rebates,
this product essentially pays for itself. “It’s important to remember the
cost of energy to operate a product over its lifetime is just as important
as its purchase price,” Natural Resources Canada said.
4. It lowers impact on the environment.
Because the Navien tankless heater only fires up when hot water is needed,
this lowers the impact on the environment. Navien’s premixed burner
releases the shortest flame, significantly reducing the water heater’s
carbon footprint. The Navien water heater reduces harmful Nitrogen by about
Compared to tank-type heaters, the Navien tankless heater reduces your
annual carbon footprint by 1,216.8 lbs. – equivalent to a saving of 62
gallons of gasoline in your car or photosynthesis of about 31 mature
cypress trees. Installing the Navien water heater, therefore, effectively
contributes to reducing carbon footprint, a primary cause of global
5. It saves space.
The Navien heating system can be mounted on the wall. This gives extra
space in your basement, laundry room or garage – areas where heating
systems are typically placed. If you live in a tiny home or even if your
home is big enough, if you’ve lived there for few years, you’ll value an
One Navien NPE-A series unit occupies 80% less space compared to a
conventional 50-gallon tank-type heater. The company’s largest unit is only
