Noritz NRC111-DV NG Condensing Tankless 8.4 GPM Natural Gas Water Heater

Noritz Direct Ventilation Condensing Water Heater 8.4 Gpm Natural GasSKU: NRC111-DVNGNoritz is proud to introduce our most efficient tankless heaters, the next generation in tankless technology - condensing heaters. This innovation utilizes a dual heat exchanger, a fusion of stainless steel and copper heat exchangers. The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger. This results in dramatic reduction of carbon dioxide and increases the heater's efficiency level to over 93%! Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting. A PVC adapter is built into the heater for easy installation.It's the coolest and greenest tankless water heater available today! This is the highest performing condensing unit on the market today. Some other brand(s) may have a bit higher efficiency rating, but there is...

So far, so good
I had this model (Noritz NRC111-DV / 842) professionally installed about a year ago. My review will not focus on installation, but strictly on the unit's operation and performance relative to a conventional 40-50 gallon natural gas tank water heater which it replaced.

I'll start with some background on how I made the decision to go with this unit. I had a 15 year old 40 gallon natural gas tank water heater in my home that was showing signs of failing...excessive rumbling from scale buildup inside the tank and inability to to produce enough hot water to meet peak demand for my family of 5. I plan to stay in my home for the foreseeable future and had no problem making a long-term investment. The primary deciding factors for me were cost (initial cost, operating costs, maintenance costs) and hot water capacity to meet peak demand. I had researched several types of tank and tankless water heaters, including the traditional 40 and 50 gallon tank units, condensing tank...

i'd buy it again, that's how much i like it
I will have to post a picture of how it looks installed, but let me start from the beginning.

I had an older conventional heater which was 40 gallons. After it was all set and done and the old heater was laying on it's side, i cut it open to see how much rust was on the inside after 15 yrs of use. To my surprise, there was none, just the anode rod was 3/4 gone. Maybe the burners were gone and that's why the hot water would run out so quickly.

Anyway, i purchased the heater from the local plumbing store. I had a hard time finding a store that would sell to homeowners, but i found one and purchased it. I am very handy and wanted to install it myself. My incoming gas line is 3/4" and the unit needs at least that to run. 1/2" gas line would starve the unit.

So, i purchased it, took out the old unit, purchased the additional line and started working on it. The unit needs to be vented to the outside and they do not provide the 4" PVC SHDL 40 pipe. THe...

junk
I purchased a Noritz NRC98-DV-NG around mid April 2014 and installed it myself. I have had problems with fluctuating water temperature since it was installed. I contacted Noritz, they did troubleshooting and told me I had a cross connection. I have never had any problems with my tank heater or my plumbing, my house was built in 2002. I called a Noritz certified plumber to come out and verify, he looked it over and said he would change out the shower valve first. This plumber did not charge me. So I buy a new shower valve $150, cut a hole in the drywall replace the valve patch all that up. I still have the same problem so I call Noritz, they say I still have a cross connection. I get a different Noritz certified plumber out, he charges $185 to show up and diagnose the problem. Plumber number 2 checks everything out and charges an additional $160 to troubleshoot with Noritz on the phone because there is a problem with the unit. They decide there is a bad circut board in the...
