I installed this NPE 180 in my own house in 2013. And, I haven't touched it since. No flushing, no flame rod cleaning, no intake screen cleaning, nothing. Still going strong. Please excuse the cob webs. Like I said, I haven't touched the thing. This was my experiment to see if the unit was worthy of installing for my customers. Discuss amongst yourselves. Gnight.

Replaced two 50 gallon tanks in series for this and the homeowners are now able to run four showers at the same time because of water pressure improvements and unlimited hot water. The old system was trying to shove all the hot water through a 3/4 inch line and it still couldn't keep up with demand before going cold. If I keep this up, maybe I'll be able to live in a 4000 sqft house on a lake with 5 full bathrooms and a two story garage that can house 14 cars. 😂
