Factors to Consider while Buying Noritz Tankless Water Heater

1. Installation

Before you opt to buy any product, the first thing that you need to consider is the installation. You can consider it with the size and the space available and also the cost that you have to pay for the installation. It is evident that the lower complications this heater will have, the better it will be for installation.

Honestly, it takes up a lot of time to purchase a new product, getting the plumbing done, and finally installing it. But if you get an easy mounting option, things can get better for you. If you have space inside, try to look for the indoor models. They are more eco-friendly.

2. Build up

The next important factor that you need to consider is the durability and the build-up of the product. Check for the quality of materials that have been used to build the internal components as well as the heating element of the product.

If it is made up of stainless steel or rust-proof materials, they are far more durable than others available. Because of this, the Noritz heater will have the chance to deter a better result.

3. Technology

Most of the products from Noritz come with a safe technology and operation mechanism. But at the same time, you need to evaluate how convenient it is to use this product for your home. You need to understand what type of indoor or outdoor unit you want to install.

The best part is that in any product you choose, the thermal efficiency is always slightly over 90%. This makes the product much more convenient to use.

4. Safety

Once you are one by selecting the type of models available, you can always use the product safely and with the help of the NRCP models. This is mainly because they are specifically designed to be safe.

But you still need to check a few things like the thermal cut-off, the temperature sensors, and the adjustable thermostat present with the product. With the help of such features, it becomes easy to keep the product safe and stable to use.

5. Rate of Flow

The rate of flow is another big factor that comes into play when you are in a hurry or even using the heater for multiple faucets. When the pressure is high or there is a rush hour, the heater splits the flow into multiple faucets.

Thus having a higher rate of flow means that it will not interrupt the shower anymore. The flow rate can range from 3 GPM to an upper limit of 11 GPM depending upon the water pressure in your locality.

6. Size

The one factor that you must consider while purchasing the unit is the size variations available. The heater is specifically designed to fulfill the entire household requirements. But the size will mainly depend on what your necessities are.

This size varies from a range of factors like the capacity and the dimensions along with the accessories. You will also have to make sure that there is adequate space available for indoor installation.

7. Troubleshooting

Though it would be fair to say that you won’t have multiple problems with the product, at the same time, it is also fair to have a troubleshooting guide. You may face some technical issues or faults after the warranty period is over.

But with a proper troubleshooting option, it will be much easier to diagnose where the problem is so that you can ask any professional to help you fix this. So this will always be helpful if you get a troubleshooting guide.

8. TurboFlow

The TurboFlow system is a great way of upscale technology that the product has. The TurboFlow technology is an advanced mechanism that allows the heater to meet higher demands in the quickest time.

Since the transition takes place in a very short period, this is a great way to maintain a safe mode of operation. The TurboFlow automatically boosts the level of heating when there is an unlimited requirement for hot water.

Another important part of any tankless water heater is the heating element of the product. Having a flame burner allows the heater to operate smoothly and also makes it much more efficient to work with the product.

However, having a dual flame burner allows the heater to work much faster and efficiently with the product. It helps to perform with reduced fluctuations and stabilized performance. This will always be helpful for regular uses.

Usually, most of the heaters from Noritz are built to last longer and to provide you with the ultimate results. However, it is also important that you keep maintaining the heater. At times, there are several problems that you may receive with the heater and some of them are as mentioned below:

1. Noritz Error Code 11

Error Code 11 usually refers to a problem in the ignition of your heater. This error code mainly shows up when the unit is not working according to the necessities and there is no sufficient gas supply present. So, you simply need to check the gas supply line and look for debris or dust. If you find any of them, simply remove it.

2. Noritz Error Code 12

The Error Code 12 is quite similar to that of the error code 11. However, it signifies that there is a weak flame, and this is why the heater is not being able to work properly. This mainly happens because of lack of gas flow. If such a problem arises, the only option is to contact a professional and get the details.

3. Noritz Error Code 16

When you are using the heater for a short time and you receive a sudden spike in the temperature, it will showcase the Error 16. This mainly happens because of the scale buildup and as a result, the heat efficiency is much lower. The only solution is to opt for a descaling procedure. It will resolve all the problems for this issue. You can also contact a professional for this.

4. Noritz Error Code 29

The Error Code 29 resembles a problem related to the drainage issues of the water heater. There is a special drain valve which is responsible for removing the acidic water. When the pipe is blocked, this error code will show up again and again. The solution is to complete a condensation on the drain line to remove the obstructions.

5. Noritz Error Code 73

Error 73 usually happens when there is an improper circuit configuration. This may happen at times when you are about to change the dip switch or the jumper connection of the heater. If this error code shows up, you need to unplug the heater from the circuit board and then wait for a few whiles. Plug it back again and the error should be resolved.

6. Noritz Error Code F76

If you see this error code shown up in the heater, it has to be a breakdown in communication between the two heaters. You need to reconfigure it again with the help of the Quick Connect Cord. However, it is better that you call a professional to do the job for you to ensure that the heaters are properly connected.

7. Noritz Error Code 90

If there is an error code 90 showing up in the Noritz heater, it resembles that there is a combustion abnormality caused by the mixture of air. The main reason for this is an insufficient gas supply due to blockage. Simply clean the lines and it will be good.
