This is my 3rd time purchasing these tanks... I bought one 2 years ago so I could use it with my off grid solar.. 2 years it's been and it's still going strong, so I decided to buy 2 more.. 1 to replace my 40 gallon electric hot water heater and another for a spare ( prepping)...
I don't know what some people are complaining about on the few bad reviews, I mean don't you people have any brains or common sense?.. it's a 7 gallon hot water heater, you can't expect a 20 minute hot shower but I can get a 10 to 12 minute shower and I like pretty warm showers... Plus on top of that it uses less than 1\3 of the electric my 40 gallon heater did, plus I can run it on solar or a small generator, it takes about 35 minutes to fully recover, and seems well built and judging from the other one I put in 2 years ago seems quite reliable..
My only complaint is I bought them returned.. one was brand new and never installed so I put that one in my preps.. the other however was installed by a sloppy plumber who marked it up with pipe dope and gouged it quite a bit.. I installed that one, it works great but should've been less than 204.00 in my opinion which was marked as like new.. but anyways no fault of the hot water heater, just incompetent people, but I saved 160 dollars buying 2 of them though so I can live with it having a few marks back in a closet where no one can see it anyways...
I highly recommend these water heaters from having one for over 2 years now and it has been 100% problem free and I have 2 of them operating in my home, one does my downstairs bathroom and kitchen and the other does my upstairs bathroom and laundry room.. the money you'll save on electric over the life of the tank will pay for itself...
Oh and by the way these small tanks heat the water up way way hotter than a regular hot water tank, so you use way less hot water taking a shower, that's way I can get a 10 to 12 minute shower, you could never hold your hand under straight hot water coming from these.. a regular hot water tank heats the water to 120 degrees where as these small tanks heat water to 140 to 160..
And they are really well insulated too will keep water hot for hours before needing to cycle on..

I first installed the ES-4 in my shop which does not have a hot water heater. So cleaning my hands especially in freezing/sub freezing temps was very uncomfortable. My well water line is deep enough not to freeze but it's still water coming from 200+ ft underground. The install was really straight forward and simple. A longer power cord would be nice but for the price point it's a VERY minor issue. I placed it directly on my cement floor next to the sink and WOW in 10 minutes I had hot water. I was concerned that sitting on an ice cold cement shop floor would cause it to burn a lot of energy. BUT to my surprise It's so efficient that I rarely see the light come on. In fact I've only seen it come on 2-3 times with over two months of use. This tells me that it's thermal qualities are excellent.

Now for the best part... I installed one in my house under the kitchen sink but never got a light or hot water :-( So I sent it back to Amazon after I tried troubleshooting the issue (which I could not figure out) and they shipped me another free. In two days I received another one and installed it. Unfortunately I had the same problem. I was thinking that it was because for some weird reason it wasn't compatible with a hot water line coming from my water heater. Because that was the only difference in installing this second unit from the original install in my shop. The reason for installing one under the kitchen sink is that my water heater is far away from my kitchen sink (freezing cold well water just like my shop) and takes a full minute to get hot water and wastes precious well water not to mention the energy waste to reheat the hot water tank.

So I called Bosch tech support and they were very patient and helped me troubleshoot the issue. In just a few minutes they solved the issue. The outlet I was plugging the unit into was only energized when the garbage disposal was turned on. Duh! I felt like an idiot because I'm pretty good about troubleshooting problems. The Bosch rep was very kind and told me that I'm not the only one that has missed this simple fix. Cudos to Amazon and BOSCH for a great product and support! Check your power source... DUH!

Got this for a food trailer, works great! It heats up water super fast. Not too big, fits nicely under my sink. It’s great quality for the price. It’s not too heavy either. It looks nice too. If you need a water heater for a trailer/rv this is a great option.

Extremely happy with the unit. Little larger than I expected. Easily (not much room under there) hooked up to the water intake. Faucet hot water in seconds rather than minutes. Hooked up to the dishwasher, works great also. Be aware that there is an anode. This could be replaced every 2 years. It is suggested to check annually. There is no drain valve to remove water in unit before removing anode. Think this is going to be a water mess.

We left it on the normal setting for the hot water heat. I don’t think it puts out as much heat as it should on that setting. We are using it for an outdoor kitchen, so it doesn’t really matter that. It doesn’t get super hot. Please keep in mind I’m sure it will if you turn it all the way up.
