Question: Does this water heater plug in or does it require wiring?
Document: This is a nice under sink water heater that only need 115V of power. Easy to install and place and just plugs into a normal plug-in. Had in continuos service in my shop and the guys love having hot water to wash their hand with.
I have thought about getting one of these for my home since my master bedroom sink is far away from my water heater, and it takes two minutes to of running the water before hot comes out. It can be installed right under the sink, but you also need an outlet to plug it into.
We hooked this up in our bathroom, so the bidet we bought could have warm water that wasn't too warm and we wouldn't have to run the water too long to get it. It works very well, with the side effect that our sink now has warm water instantly. We are  very pleased with this little heater that fit in a nook we had.One of the big selling points for us is that you just plug this into an outlet, rather than having to wire it into the system.
Installing this water heater under the sink was a fun time as I did my homework and took my time. I even plumbed the pressure relief valve to the sink drain fitting that was designed to access the drain plug control rod. I used a 3/4&#34; brass to a 1/2&#34; Pex combination. The newer designed tank came with an external temp control which eliminated some of the adjustment problems that other customers had complained about.
We measured the inside and outside openings on the connections and went to Lowe's and found what we needed. We had an electrical plug under the sink already for the dishwasher and disposal. I don't use the disposal, so I used that plug. You probably could have an adapter for a third plug-in, but you might have a power problem if you tried to use two things at the same time though. It's REALLY NICE and convenient having instant hot water.
I have a sink in my arts and craft studio, but even cleaning artist brushes, hot water is nice. I bought this one because it works on a regular 110 plug, without a dedicated circuit, which I don't have. The tank-less water heaters  all seem to need a dedicated circuit. It took a little for me to plumb the pop off valve into the drain, but if I can do it, nearly anyone can. I am a 60 year old artist, do it yourself female.
works great plug and playhad no problems with this productyou need to have a plug under your sink which is very rare so plan on getting one installed
I sent my unit back as defective and requested a replacement. In retrospect, I am not sure it was defective. The replacement had the same problem. It did not heat the water. The manual said that the thermostat was set to 120 deg F.  It wasn't. To get to the temp. adj. you have to remove two cover plates and expose the guts of the wiring. There is no dial, so adjustment is trial and error.
I have installed one of these under 3 different sinks over the last 8 years or so. Each of them is wired to a wind up 15 minute timer and only gets turned on when hot water is wanted. I've replaced each of them at least once. After I replaced the first 2 of them I extended the wiring and plumbing and moved them outside under the house so when it (inevitably) blows out it does not cause interior water damage.
I picked this small unit because it was on a mudroom sink that would not require a large volume of hot water at any one time (basically washing hands). I put it in line with the hot line in case I needed a large volume of hot water occasionally, and the piping is somewhat simpler that way. I installed underneath the sink so it is very accessible for the recommended annual maintenance.
Answer: yes
