Tank versus Tankless

We own a small tankless Bosch water heater so thought this might be a good addition to the kitchen sink. Unfortunately it didn't work out for our needs as expected. There are a few things to keep in mind when considering this unit. Tank versus tank-less. This is a small tank unit...it is NOT a tankless unit. There is a big difference in usage patterns. For example, a tankless unit basically requires running water which is heated as it passes through the unit. There is no tank, no storage and so it is "endless"...as long as the water runs through the unit, it keeps coming out hot. This is a small tank unit that works just like your large tank...it stores a couple of gallons of water inside a small glass lined tank which is then heated to the temperature set on the thermometer. It WILL run out of hot water as soon as the tank empties. Desired Application - Energy Savings or Water Savings. A tankless unit saves energy because you only heat the water when it's needed. On the other hand, a small tank unit saves water by allowing instant access to hot water rather than having to run the water for a couple of minutes until it heats up. Buy a tankless unit if you want a continual supply of hot water on demand. Buy a small tank unit if you want to reduce the total amount of water being used...this will preheat the water so hot water comes out instantly when the faucet is turned on...no waiting while the hot water runs across the house. Installation. This is MUCH easier to install than even the smallest tankless units. This runs off of a standard electric plug...plug in anywhere...and two standard hoses used on almost any sink (kitchen or bathroom). A tankless unit typically requires hard-wiring and plumbing modifications. Now, one word of caution...for those using newer sink/faucets, the connections may require an adapter...ours did for testing purposes. Performance. In testing this worked well enough to get hot...too hot to touch for the first gallon or two...and then quickly turned cold as the water temperature dropped. When installing inline via the hot water, the water was hot almost instantly rather than the roughly 1-2 minutes it normally takes to travel to that bathroom...it was hot enough to be uncomfortable and then gave way to running hot water from the regular hot water heater which remained at full temperature. Basically no lag time or waiting which is good. Bottom line - this reduces or eliminates the lag time while waiting for water to heat up/transfer in a distant faucet but does NOT supply a continual/endless supply of water like a tankless unit. Good option for pre-heating water at distant faucets and saving/reducing water usage.

Our problem was we have a very nice demand water heater installed at the other end of ...

Our problem was we have a very nice demand water heater installed at the other end of the house. So to get hot water into the kitchen, we had to wait for quite a while, or decide to wash hands/dishes with cold water. Not fun. I elected to buy the 2.5 gallon version of this heater. I vacillated back and forth between it and the 4gal, but this one won out because of it's smaller footprint. That was important because the cabinet underneath our sink is full of all sorts of stuff that we never use. I felt I could squeeze the 2.5 in, but not the 4 gal version. Sure, I could have found some other cabinet to keep all the stuff we never use, but they're all already full of stuff we never use. So that wasn't an option. Install was very straightforward. I simply connected the hot water line coming to the kitchen to the cold water input on the water heater, and the hot water output from the water heater to a little gadget that splits the flow between the kitchen sink and the dishwasher. The only other installation issue is it does require three quick trips to the hardware store to get the necessary fittings. I have heard tell of folks that have done this in one trip, seemingly getting the right parts the first time, but that has not been my experience. Using it, the thermostat is set to something called "Ideal," or "Just right," or some other equally informative thing.. It was not ideal and had to be turned up a tad to get the water more than warm. But the thing is doing what I had hoped it would do! It's something to get used to the fact that when you open the hot water faucet, hot water actually flows out of the thingy. What a concept!

This little hot water heater is AWESOME! It is super well insulated

I am using this as a hot water source in a van camper. This little hot water heater is AWESOME! It is super well insulated, very efficient, compact, silent and robust. Once hot it will maintain the water hot enough for my outdoor shower for 24 hours. It draws about 25 ahr's to heat the tank to its max temperature. Mixing the water down to about 98 degrees yeilds 5-7 gallons of hot water for shower and dishes. This is more than enough for a warm rinse off for a couple of people after a hike or a swim at the beach. Great little water heater. Love it.

Yea, instant hot water finally at my kitchen sink!

I'm very happy with this. I was tired of waiting almost a minute for hot water to get to my kitchen sink and now it is instant. It took a little hunting at home depot to find the right t-connection and adapters to hook both my faucet hot water and dishwasher to the output, but I got it done and it works great. I used the input to the unit from the main hot water tank because I wanted to be able to have more than 4 gallons of hot water when I wanted it; also so that there would be warm water in the unit when I was done and it wouldn't take long to reheat. So far, I'm happy with that decision. I can easily change it later if I choose. As a test I let it run for 4 minutes to see what would happen with temperatures, because there would be a point that the 50 seconds of cold water in the pipes would enter the new heater. I got about 50 seconds of good hot water, then it became warm, but not cool. It stayed that way for the full 4 minute test. I expected it to get cold for a few seconds, once the cold water hit the tank and the 4 gallons was used up, but that didn't happen. I then expected the water to get hot again once the main hot water was flowing through, but that didn't happen either; it stayed just warm (might have to do some more testing and/or tweaking of the main hot water). It was a very good purpose on my part. BTW: I installed it on it's own 15 amp breaker (stole it from the dishwasher and moved the dishwasher circuit to the same breaker with the disposal).

it looks like they have improved the thermostat

Haven't had this for long, but based on so far: I don't know how anyone could complain about this unit. Hook up is about as simple as it can get, just used the same faucet supply hose and plug it into an outlet. From previous reviews, it looks like they have improved the thermostat. I started it on the ideal setting and the water was warm enough to wash hands but not hot enough to shave. turned it halfway between ideal and max and I wouldn't want it any hotter.

works good

I decided on this unit because of the many positive reviews. I had it installed by a licensed plumber on Jan 30, 2017 for my salon sink. It stopped working the next day, I followed the directions in the manual to reset it and it worked for a few more days. It no longer works again... tough to provide hair washes with cold water. I'm very unsatisfied with this unit! Bosch used to be a good brand name from Germany. I noticed this unit was mfg. in China... This is ridiculous! Registered it with their customer service, still waiting for a reply. Ok, I had to change my review because I was able to remedy this situation on my own. No help from their customer service, which never did anythingbut send an email. It seems that you cant turn the thermostat all the way up or it overheats and shuts itself off. So, I backed it off to about half and it seems to be working fine. Therefore, I'd say it's a good product for the price. I now give it 5 stars but 0nly 2 for customer service.

Crawlspace install - Instant hot water in the winter!

I can't speak to the longevity yet but so far I should have put this in years ago. Instant hot water to the kitchen sink which is over 40 feet from the main hot water tank. With the plumbing running through the crawlspace I used to have to wait a minute or two for hot water. Not any more! The kill-a-watt electricity meter told me it will cost me $25-$30 to run over the course of a year. I mounted it inline on the hot water side in the crawlspace but still under the kitchen sink to save room on the main floor. I used a couple sharkbite connectors and flexible hoses to hook it up. I bought an adapter to mount a garden hose thread (GHT) to the overflow into a 5 gallon bucket.

Perfect for 5th wheel RV

This 7-gal hot water tank is perfect for my RV. Plenty of hot water for my shower and heats up quickly. The manufacturer puts putty on the threads of the pressure release valve, making me think it was used so I had it replaced but learned they all come that way. Other than that it was pristine condition. Installation was pretty easy, I had a friend who used to be a plumber help install it. We used 3/4" elbows from hot and cold valves connected to 1/2" braided tubing to attach onto my PEX flexible tubing. We also had to buy something for the wiring to help secure the wires in the box. I bought a small garden hose and attachment from Ace Hardware to fit the pressure release valve so any water that might flow from valve will go outside to prevent leaking. I'm very happy with this heater and would recommend it to anyone who wants to replace their propane water heater to electric in a RV.

Great heater for RV too

I purchased this for my rv, it has worked outstanding. The reheat time is great. I replaced the gas/electric unit with this electric unit. I have had no problems and have not run out of hot water in the shower.

Very impressed with performance so far!

I have used this water heater for over a month now, and I am very impressed. No more waiting 2+ minutes (and wasting 3+ gallons of water) to wash a few dishes. One of my biggest concerns when purchasing this heater was the "lapse" time from when this tank emptied to when the actual hot water arrived. We wash dishes 4-5 times per day (large family), and we have YET to experience this! I had to cut into our cabinet for the install (we have very small under-sink space), but that was no problem. Regarding the connectors, I was concerned after reading others' comments. And I DID have to make two trips to Home Depot; however, my configuration is very simple. I used regular 1/2" compression fittings (with teflon tape on everything) on the top of the heater. I have 3/8" compression fittings on my supply line and faucet, so purchasing one 1/2 to 3/8 reducer worked for my valve-to-tank connection (because I already had the 1/2 x 1/2 line), and a regular 1/2 x 3/8 supply line worked from my tank to my hot water faucet supply. I did not hook my dishwasher to the tank, as we rarely use it. Finally, I fashioned a discharge line by using a step down reducer and a piece of 3/4" pvc (with teflon tape), a length of dishwasher hose, and a new dishwasher tailpiece. I hope this helps you with your decision-making and installation.
