InSinkErator H-HOT150SN-SS Instant Hot Water Dispenser System with Stainless Steel Tank, Satin Nickel

Water heater works well after 2 hour installation on 3/12/26. One of the fittings on the copper water line was missing. My plumber luckily had the fittings needed with him. This one replaced the same size model we purchased in 2010. Our gets daily use. I would recommend this product.

If you are comfortable putting a new faucet onto a sink then this should be no trouble for you. A pro plumber should have no trouble at all. All you need is a spare hole in the counter where you want the hot tap to go, and a 115v socket under the sink where you want the main unit to go. Keep in mind that the socket will need to be hot at all times to keep the water in the tank hot. My socket was switched so that it controlls the garbage disposal. I was replacing my disposal at the same time, so I added an insinkerator countertop switch (requires another spare countertop hole). Now I just leave the wall switch on, which keeps the HOT150 powered, and use the counter switch to turn the disposal on & off. If i want the hot water off like if I'm off on vacation, I can just flip the wall switch. If you don't have a countertop hole for this, you might need to rewire your under-sink socket so it has a switched socket, and an always-hot socket. The water lines provided are somewhat short, so I got a 18in piece of braided stainless hose and adapted it to the lines from the unit. The unit uses a 1/4" copper tube as its main feed line, so you will need to purchase a T-fitting to add a new outlet on your sink's supply to feed the unit, and a compression fitting for the copper line, plus whatever other tubes and adapters. In my setup I have a standard sink tee->braided hose->stepdown adapter->compression fitting. you may wind up with something a little different depending on if you need the extra hose and what fittings your store carries. once you have all the connection bits its really plug and play: drop the faucet in from the top, screw the unit to the wall, plug in the lines from the faucet to the unit, connect the copper feed to the sink supply. Then you flush the unit for a couple of min and plug it in. Job done. In operation its pretty simple. I didn't flush as carefully as the instructions say and I did get some gurgling noise when its heating for the first day or two. I also found that when turned all the way up it actually boils the water inside. Possibly due to some air pockets, but I'd leave it set at 75% or lower to start, as it can definitely heat up above 212deg in some cases. safer to start on the cool side and bump it up till you get the temp you want. After I got the temp dialed in and the air flushed out its been quiet and excellent. I live a lone so I'm making single drinks at a time - I don't know if larger families might find the reservoir too small. Overall if basic plumbing (and possibly a little electric work) don't bother you this should be easy to install and seems to be a nice unit.

We had a previous dispenser tank that developed an internal leak. I took it apart, and a clip broke (plastic) and a hose was leaking. I decided to get the insinkerator and just installed it. We reused the old faucet with some redesign because of the open venting requirement, but it works as advertised. If you use the packaged faucet, you probably won't have a problem. I guess to make it fool proof, there are 3 different types of connectors. The inlet is a a seated 1/4 line push on connector. The output and vent are different sized vinyl push on lines. Instead of vinyl, I wish it was just a threaded connector with 3/8 push on for the output and vent. I was told long ago that tanks don't like RO water, that it breaks component down more quickly. Since the lifetime of these tanks is probably limited, I would probably not worry about it but I added a C**an input water filter. I like this one because I can mount it in a more accessible place than near the tank because I change the filter twice a year. BTW, compared to my old system, serves much hotter water, but there is more of a delay on starting the water flow, maybe 5 seconds, perhaps because this is open vented and my old one was not. After some research, some people claim it was air that came out. What comes out of the vent via a one way valve is steam and water. So the faucet must purge this out the hot side of the faucet. I modified this by hooking the vent to a saddle drain, which is just a drilled connection to a drain, the kind that RO system use. Saddle drains have a push on connector poly so it was easily converted using a hose to poly connector on the tank. The one thing I added was a simple 9v leak detector that I placed below the dispenser. My previous tank leaked, and this prevents a flood under the sink.

This model replaced one we had that lasted 5 years. The older model had the push button tap, which finally would not turn off nor would the water tank heat the water over 170f. This model has an easy to use lever, and the heating chamber brings the water temperature up to proper temperature for hot tea. 185f easily. My only moan is that most home kitchen faucets have a 3/8” water supply line under the sink, so a trip to the hardware store necessary to buy a reduction T fitting down to 1/4” along with compression fitting. Inexpensive yet necessary installation parts that ought to have been included! I live 45 minutes from the nearest hardware store and upset that I had to fetch these. That’s my reasoning for not giving 5 stars.

So this is my fourth one that I purchased from Amazon for my home they are so good. They work well and they’re excellent one. The heat went out one. The electric went out. I don’t remember with the other two, but I don’t think that’s bad for my first install in 1990 and we use it all the time every day multiple times a day.

My former hot water tank started leaking and was not repairable so I bought this one to replace it. It is super easy to install though a second set of hands can speed along the process. The faucet is also easy to install. It works perfectly to dispense instant hot water to rinse off dishes (great on greasy items), to warm up a cup before pouring coffee or tea, or get super hot water to boil for pasta. The hot water dispenser can also be used to rinse off sticky honey jars, loosen metal lids on glass jars, wet a cloth to clean counters and other areas, rinse off a serving spoon before reusing, heat a knife before cutting a flourless chocolate cake, or warming a spoon before digging into a rock hard carton of ice cream! Get it as you'll never imagine how you managed without one!

Good quality and very functional...glad I purchased the lever action rather than the push button...like the way that the lever springs back (safety). My plumber installed it when he was doing something else for me, -so I don't know how it would gone for me...was easy for him. This item has turned out to be even more useful for our daily routine than I initially anticipated. Good purchase.

J'avais des doutes au début, car son prix équivalait à un robinet de remplacement pour mon chauffe-eau précédent. Il est installé depuis 5 mois et nous en sommes toujours ravis. Si le bec du robinet avait été un peu plus long, ça aurait été génial, car l'installation avec un évier sous-comptoir le distance beaucoup du bord.

I have just recently install this under counter hot water tap. The tap and water container appear to be well made and, so far, have bee working perfectly. My only complaint was the difficulty in installation cause by the overly short threaded post which is provided for tightening the unit under the counter. I have a 1 1/2" thick butcher block counter. The unit could not be installed used the plastic shim, only the c-shaped metal washer and nut. I think I lost some of the tightening capability because of this. A significant design flaw I think for thicker counters.

Very easy and quick to install and produces lot of super hot almost boiling water. Excellent for making tea! You will probably need to make a trip to the hardware store to buy the correct fitting for the water connection though- it’s not included in the box. In spite of this it works so well that I still rate it at 5 stars. The finish and function of the included faucet are also both very, very good. It looks great!

This was to replace the one we had. Works fantastic. Once you have this you will wonder how you lived without it before! No kettle to wait for, instant coffee, hot chocolate, tea ready in seconds.
