Before You Buy: Noritz NRC66DVLP Checklist
The first thing to check is whether your existing home infrastructure supports a high-efficiency condensing system, as these units have specific venting and power requirements.
- ☐ Confirm your venting system is compatible with Schedule 40 PVC Pipe and Fitting
- ☐ Verify your power source is within reach of the 6′ power cord
- ☐ Check that your water supply can support a 6.6 Gallons Per Minute flow rate
- ☐ Budget for a professional installation to ensure the high-efficiency system meets local building codes
You should not buy the Noritz NRC66DVLP if your current venting setup cannot be adapted to Schedule 40 PVC or if your electrical source is located further than 6 feet from the intended mounting location.
What the Numbers Mean in Use
Low NOx Emissions
Low NOx emissions on the Noritz NRC66DVLP mean the unit burns fuel more cleanly than standard models. This feature helps you maintain a cleaner indoor environment and aligns with stricter local environmental standards without sacrificing heating power.
PVC Pipe Venting Compatibility
PVC pipe venting compatibility for the Noritz NRC66DVLP allows for the use of Schedule 40 PVC pipe and fittings. You can utilize this standard material for your venting system, which often simplifies the material sourcing process compared to metal venting requirements.
High Efficiency Operation

Is the Price Right?
The Noritz NRC66DVLP sits at the $1336.11 price point, which is $41 above the $1295 average for the similar tankless water heater installation products we compared. At this price, you receive a high-efficiency, low NOx unit that includes a remote thermostat and a 6′ power cord.

The Noritz NRC66DVLP is the right buy if you prioritize high-efficiency performance and specific low NOx emissions over the lower entry prices of non-condensing units. Since the data does not provide a specific BTU-to-gallons-per-minute conversion for monthly utility costs, you should check the unit’s efficiency rating against your local gas prices to calculate your exact monthly savings compared to a standard tank.
Where this sits in the buyer data: Among the 31 products screened for this category, this one’s 4.3 rating places it #14, on 21 ratings – below the 170-rating median of that group, so treat the average as less settled than its comparables. On price it undercuts 6 of them.
