It works for a while
It took 3 years and 4 months for mine to die. It worked fine with daily use for those 3 years in my kitchen sink which is on the opposite side of the house from my main water heater. I used this for instant hot water. Installation was easy though I did need to buy an adapter fitting to make the faucet hose fit. What is not immediately obvious is apparently this thing is made with cheap metal that corrodes, so you have to open it up annually to replace an anode rod, or it WILL rust out

    For the Kitchen Sink and Dishwasher
    Took three gallons of wasting water for the hot water to reach the Kitchen Sink. This worked out perfectly, hot water in like 2 seconds. After we deplete the 2.5 gals of water in the tank my House hot water already to Kitchen to take over.

      Defective pipe thread causes big problems
      Once installation was completed, turning on water resulted in big problems; water spraying out the inlet fitting. Disassembly showed the cause was a defective pipe thread. It looks like a couple of tiny drops of solder or something was in the groove, preventing the fitting from sealing properly even though tight as possible. Debris was firmly attached to thread and could not be removed. Home Depot Customer Service was excellent with item return. Product looks to be what I expected so I have reordered and will try again.

        Great until it leaked
        This unit is easy to install without the need of a plumber and provides sufficient hot water where it’s needed. The issue that I have is it only last 2 1/2 years before it started to leak, causing wood damage under my kitchen sink. It turns out that Bosch expects the owners to disconnect, drain, remove, inspect, and replace the heating element anode annually. If this is not document, then the 6 year tank warranty is voided. When I removed my heating element, the anode was corroded and had all but disinegrated. Totally not worth the money and damage it caused and Bosch ought to be ashamed for producing a faulty product and an even worse warranty

          Tank Water leak after 27 months with 6 years warranty on tank
          Water leak all over the floor after a little more than two years. No warranty enforced and Home Depot refused to exchange. Bosch support is terrible..It is not a reliable product and misleading label.

            This Bosch Mini Tankless Water Heater is totally awesome. If you have a kitchen island or bathroom that is slow to deliver hot water, this is the solution. Easy to install under your sink and it gives you instant hot water. A fantastic product.

            Required hidden rod maintenance for 6 years tank warranty.
            Don't be mislead by limited 6 years warranty. My water tank burst after 2 years 5 months and not covered because the Anode Rod has not been inspected/replaced yearly. You have to tear up the machine, remove the anode rod, call Bosch tech support to buy the rod over the phone. Few days with unit tear down for this replacement. Not common practice for home owner with just warm water under the sink. 2 years warranty is good enough for the advertisement so the buyer will make the decision. Limited 6 years warranty is very misleading. Do not buy if you are not handy. Look for 120V/1.8KV tankless instant heater instead of 2.5 gallons.

              Easy to install. Its bigger than the picture looks so make sure it will fit under your sink or wherever. It heats up fast. Time will tell how it holds up. I will stay on top of the maintenance. Hopefully that avoids the leak problem that other people left in the reviews.

              The heater was easy to install, plugs into regular wall outlet-nice! We were surprised how fast it heats up the water. We wanted a small water heater under a small sink unit. Fits well and it works out great. Very satisfied, great product and brand name.
