Water Heaters and Models
Q7: How do tankless water heaters from Noritz work?
A7: Noritz water heaters only heat up water that is demanded – on demand hot water. When hot water is required, by a device or person, the Noritz tankless water heater instantly senses water flow. This triggers the Noritz boiler to instantly heat the water. The Noritz heat exchanger heats the water continuously while there is a need for hot water. Once hot water is not needed, the Noritz tankless water heater will turn off and conserve the gas that it is running on. Similarly, the Noritz tankless hot water heaters will continually heat the water, indefinitely if there is no drop in demand, thus having an never ending supply of hot water, an advantage over tank storage water heaters.
Q8: Is there any difference between a tankless water heater and a tank storage water heater?
A8: Tank storage water heater have a limited amount of hot water that can be supplied. Once the tank runs out of hot water, it will take a while for more water to heat up again. Also, the tank storage water heater heats water, even when you do not use it. This raises the operating cost of heating water.
The tankless hot water heater only heats the water that is needed and has the ability to run indefinitely
The residential tank storage takes up a large footprint in a home. Whereas, the tankless water heater only takes up a small footprint and can be installed indoors or outdoors.
Q10: Which Hot Water Heater from Noritz will match my needs?
A10: The ideal way to estimate your hot water usage is by estimating the peak flow capacity of hot water that you will require at any one point in time. For households, this might mean how many showers will be running at one time. You multiply the flow rate of each shower by the number of showers. This calculation should be done by a certified Canadian plumber or contractor. When the maximum flow rate is calculated, you can reference the specifications for the tankless water heaters. You can also call Noritz any time for support. 1-888-382-6568.
Q11: How long do tankless water heaters last?
A11: Tankless water heaters in general last longer than Storage tank gas water heaters. Noritz tankless hot water heaters are made with the highest quality parts are tested thoroughly for high quality. Also, Noritz tankless hot water heaters also have replaceable parts, to increase the life of the best tankless hot water heater.
Q12: Will hot water instantly come out of my faucet?
A12: No, in fact this is a common misconception. A tanless water heater instantly heats the water at the source. The hot water will still need to flow from the Noritz hot water heater, to the faucet. If you are searching for an instant hot water solution, you can install a recirculation pump. Ask your installer to see what options you may have for instant hot water. Noritz recommends you use one of these brands to keep your warranty valid: An on-demand system, such as ACT/Metlund® Hot Water D’MAND® and the Taco D’MAND.
Q13: Do I need to upgrade my gas line?
A13: Depending on your model, the minimum gas line size that is required is ¾”. Tankless heaters usually require a bigger gas line because it requires higher BTUs. It requires more, because unlike the tank water heater, gas is only required in short bursts when it is needed. Talk to your installer to see what size gas line you may need.
Q14: If a tankless heater requires higher Btus, doesn’t this mean it uses more gas?
A14: No. The amount of gas you use to heat up water is the same amount. The only difference is the time you take to heat it up. For example, if you boil two pots of water but one was on high and one was on low, the amount of BTUs required would be the exact same. The only difference is the amount of time it will take to boil. The energy savings comes when you are not using it, it does not use any gas.
Q16: Can I use my existing venting for my tankless water heater?
A16: No. Tankless water heaters require a Category III gas tight and corrosion resistant. The exhaust is slightly acidic and may corrode the standard vent piping. The vents must be gas tight in order to avoid carbon dioxide leakage. The Noritz tankless water heaters use a powered exhaust fan to push the gas out. Note: Schedule 40 PVC or CPVC can be used for venting on our condensing technology tankless heaters only.
Q17: Are there any electric tankless water heaters from Noritz.
A17: No. Noritz only makes Natural Gas and Propane tankless water heaters. This is because electric tankless water heaters usually are only for the point of use. The electric tankless heaters are not intended for the whole house and does not qualify for the energy star program because they are inefficient. It has been reported that some gas companies will offer a gas line for free if it is in their territory.
We do not offer any electric tankless heater models for homeowners that only have electricity. We only offer natural gas and propane models. Our tankless water heaters are designed for the whole-house, meaning our units can provide enough hot water for an entire home. There are electric tankless water heaters available on the market, but typically a single unit’s output is usually not enough for an entire home and do not qualify for the Energy Star program. Other disadvantages include the large amount of energy consumption that is required to heat the water and it usually takes longer to reach the hot water temperature level at start-up. In areas where there is no gas available, some gas companies do offer gas lines to be installed to your home. We have heard of gas companies in certain areas to offer free gas line installation to homeowners in their service regions.
Q18:Do I need to install a water softener for my tankless unit?
A18: No. It is not required to install a water softener, but if you do live in an area that has very hard water it will eventually harm the performance of your tankless water heater. Some things you can do is to add a water treatment system such as our ScaleShield which prevents scale from forming inside the heater’s copper piping, a whole-house water softener system, or do a routine flush maintenance (frequency depends on your water hardness level). It is recommended to have your installer test your water hardness or contact your city’s water department for the water test report. Water hardness levels in excess of 12 grains per gallon entering the heater will significantly affect its performance and void your warranty.
Q19: How many tankless heaters do I need for my home?
A19: Our tankless heaters are designed for an entire home. Our smallest unit can provide up to 6.6 gallons per minute and our largest unit can provide up to 13.2 gallons per minute. Some heaters have the Quick-Connect feature which allows identical heaters to be linked to double its output. So how do you figure out how many gallons of hot water you need for your home? Here are some helpful tips:
1. How much hot water do you use at the same time? A standard shower head, dishwasher, washing machine is about 2.5 gallons per minute each. If you typically use all three of these at the same time, that would require 7.5 gallons per minute or the NR98 series. Bath tubs are usually 6-8 gallons per minute, and rain head showers and body sprays definitely requires more hot water than a standard shower head. So if you demand more hot water you will need a larger sized unit or another identical unit with the Quick-Connect feature.
2. Remember to pick the right size unit for realistic situations rather than for your current situation. For example if you have 3 showers in your home, but you only use one shower, you might think the smallest unit is plenty for your situation. The problem is if you have visiting guests over or if ever sell your home, the hot water demand may be different and the heater may be undersized, possibly causing difficulty in selling your home.
3. Here’s the most important tip to understand. Tankless water heater’s gallons per minute output depend on your tap water’s temperature. Simply put, the colder the water the less output you will get from the heater. This is because the colder tap water temperature requires the heater to heat the water more than if it was heating water that is warmer. So we recommend choosing your heater based on your winter season’s tap water temperature. This way you are covering the worst case scenario for your area (consult with your plumber or contractor for final application sizing).

Q21: Where can I purchase a Noritz heater?
A21: Our units are not sold through retailers. They are only available at professional wholesale distributors. Tankless water heaters require gas line upgrades, stainless steel vent runs as well as local code requirements. Therefore our heaters should only be installed by a licensed professional. Warranty will be void if our units are not installed by a licensed installer.
Controlling the Heater
Q23: Why are there no prices listed for the products?

Q25: Do I need a remote controller?
A25: Noritz tankless water heater comes standard with a remote digital temperature controller, which allows you to adjust the water temperature. The controller is optional only on the NR-50, NR-66 & NR-71 models. For other models, the control panel can be wired and installed in a remote location; up to 300 feet away from the unit. The water temperature is displayed on the easy-to-use control panel, and can be adjusted using the up and down buttons.
New safety lock-out feature requires the user to follow these steps to go above 120°F:
1. To go above 120°F you must first turn off the power on the remote.
2. Press and hold the flow meter alarm set button until a sound is heard (2 sec.).
3. Change the temperature using the setting buttons to go up to 140°F (WARNING: temperatures above 125°F are scalding!).
4. Set the power button back to on.
Note: If you want to go above 140°F, please contact your installer.
