What Are The Different Types Of Noritz Tankless Water Heaters?

Noritz offers several types of tankless water heaters, including natural gas water heaters and propane water heaters. 

Noritz noticeably doesn’t offer an electric tankless water heater due to the fact that Noritz prefers to provide whole-home solutions compared to point-of-use models that electricity can support. 

Noritz Natural Gas Tankless Water Heaters

More Americans use natural gas to heat their home’s water than any other fuel, potentially due to the convenience of using the main gas supply line. Natural gas costs less than both propane and electricity, but the prices fluctuate more drastically. 

Natural gas water heaters produce more toxic emissions, such as carbon monoxide, into the air. It also creates more safety concerns, but accidents don’t happen often.  

Noritz Propane Tankless Water Heaters

Propane provides a cleaner fuel option since it doesn’t produce pollutants. It also generates more power using less fuel, making it the more efficient option. 

However, propane comes with a higher cost per therm and requires regular delivery. Plus, you need to regularly change the propane tanks. 

What Are The Pros And Cons Of Noritz Tankless Water Heaters?

Noritz tankless water heaters come with both advantages and disadvantages that can help you determine if Noritz makes the right products for you. 

Pros of Noritz Tankless Water Heaters

Noritz tankless water heaters have a number of benefits, including durability, easy installation, and innovation. 

Noritz makes a point to use high-quality components, such as commercial-grade copper cases and copper heat exchangers, that prolong the life of their devices, making them some of the longest-lasting tankless models on the market. 

Noritz makes their products as easy to install as possible by placing connections on the top of the unit instead of the bottom. They also allow the plumber to customize ventilation to your specifications using different accessories. 

Another benefit of Noritz products involves the devotion they put into tankless gas water heaters. Noritz only makes gas tankless water heaters, and they perfected the process, creating numerous innovative products throughout the years and continuing to put that innovative spirit into new models. 

Cons of Noritz Tankless Water Heaters

Every company has room for improvement. Noritz tankless water heaters don’t offer wifi on many models, don’t offer electric tankless water heaters, and they tend to cost more than similar models. 

One main issue consumers point out is that Noritz only offers gas tankless water heaters. Anyone interested in conventional tank gas water heaters or electric water heaters will not find an option through Noritz. They also don’t offer a distinct point of use water heater. 

Noritz only offers wifi on a limited number of its water heaters. However, we can assume they intend to include it in most future models from now on. 
Finally, Noritz costs a little more than comparable items from other brands. To add to the cost, all models must get professional installation that costs an average of $1144.00.

Overview Of Noritz As A Company

When you are making an important purchase for your home, you want to know you are buying from a company you can trust. Here is a look at what you can expect from Noritz.

Manufacturing Process: 

Noritz prides itself on making high-end products, so they put each and every product through rigorous testing before allowing it to leave the factory. 

To maintain additional control on quality, Noritz retains ownership over all manufacturing processes, including the creation of the components. Noritz does not outsource.

Ease of Use:

New tankless models come with the remote controller and/or wifi capabilities, making them as easy to use as an app on your phone. 

However, older models don’t have the same technology, making them more complicated. 

Safety Concerns:

Noritz tankless water heaters come with a number of safety features on all models to prevent excessive pressure, scalding temperatures, and gas leaks. 

As part of their safety precautions, Noritz also requires all customers to get professional installation in order to make use of the warranty. This can cost more, but it eliminates safety hazards from improper installation. 

Overall Effectiveness:

Noritz tankless water heaters rank highly in overall effectiveness.

You can expect your Noritz tankless water heater to work as expected for over 20 years. If something does go wrong, they have one of the best warranties in the industry.

High Efficiency

Noritz products range from .80 UEF to .98 UEF, making them much more efficient than traditional water heaters. Condensing tankless water heaters run more efficiently than non-condensing tankless water heaters. 

Endless Hot Water

You won’t have to worry about running out of hot water ever again!

Tank-style units stop providing hot water once you use up the water in the tank. After that, you need to wait for the device to heat up the new water that enters the tank. With tankless water heaters, you get on-demand hot water until you shut the faucet off.
