Product Description

The Eccotemp i12-NG has a new revolutionary design, making it unlike any other tankless water heater on the market today. This model features a sleek black glass casing, fully automatic temperature controls for precision, touch screen, and LCD temperature display which shows output temperature as well as GPM flow. Rated at an impressive 3 GPM, the Eccotemp i12-NG Tankless Water Heater is a natural gas fired, indoor model designed for small to medium hot water production where you need more than one hot water application at the same time.

The i12-NG comes with a horizontal stainless steel vent kit, ready to install and with its 120-volt UL listed power cord powering the internal exhaust fan and digital display.

Definitely NOT a new unit!

Definitely NOT a new unit!
Well, my water heater arrived today ahead of schedule. So that was nice. However, I'm concerned that there may be problems with it. First, upon opening the box, I noticed the water heater was wet. The box was dry, as was everything else in it. Turned out not to be water, but some sort of thin mineral oil or something of the sort, possibly (hopefully) for preventing corrosion or something during shipping. Second, this unit is very clearly used, possibly refurbished. See pictures of scratches, scuffs, pry marks, green nail polish paint touch-ups, thread sealant, etc. (Pictures were taken after wiping the oily substance off the unit.) This was listed as a new, unopened unit. I would not have paid full price for a refurb/used one. The only things new in this box appear to be the front glass on the heater, and the bag of screws and adapters.I'm giving two stars for now, mostly for the quick arrival especially considering the weather we've been having. Will update when I find out if it works.*Update*I upped my rating to four stars, because after I finally got the water heater installed it works wonderfully. I couldn't be happier with the functionality of it, especially after being without hot water for a couple of weeks.I still won't give five stars because of the fact that I ordered and paid the price for a new water heater, which this very obviously is not. All but one screw was missing for the top and bottom covers, along with all the problems listed above.
