Bosch Electric 2.5-Gallon Mini-Tank Water Heater Tronic 3000 T

Moynard: I used to turn the water on, walk away and return after at least 5 minutes because it took forever for the water to warm as it traveled over 55 feet from the water heater to the kitchen sink. Now the water is hot almost instantly. I never seem to need enough hot water to empty the tank but if the tank empties it is followed immediately with hot water from the water heater. I am so happy my husband bought and installed it as my holiday present last year.

DDos: About five years ago and after a couple of years listening to my wife's complaint about having to wait for hot water to the kitchen sink, I researched and found the Bosch line of mini heaters. The instructions say to have installed by a professional installer. I did not. I purchased, installed myself (connecting the existing hot water line into the cold water inlet of the heater), filled it up, plugged it in and that was it! Being VERY happy with this upgrade, I purchased a smaller size for under her bathroom sink with a 10 ft run to my sink as well. Up to this point I had not connected the emergency relief valves to anything. If one went off, the cabinets and contents were going to get wet, at a minimum. A few months ago I installed both in suitably sized plastic tubs found online and ran piping accordingly from relief valve to tub -- not a perfect solution, but I am satisfied; a more professional connection to a drain would not be too difficult. Side note: The anode rod is easy enough to replace if one just keeps a note on the calendar to do so and worth the effort to extend the life of the tank.

Gregory Wells: I've had two of these water heaters. Both started leaking within about two years. After the first one died, I assumed it was just a lemon considering the many positive ratings so I replaced it with the same type. I didn't bother with a warranty claim. Now the replacement unit has started to leak after 18 months. I'm on city water with no unusual circumstances that are obvious to me. My last whole-house water heater lasted over 15 years and I have several spot water heaters that have been working fine over this same time period.
Correction- The manual says a visual inspection of the anode should be performed every 12 months. I checked this and the anode is completely gone. So this is my error. One of the many labels on the case says to have the anode inspected annually. This sounds like overkill; in my situation it certainly was not.

Doug Morgan: This unit is awesome every time I turn on my hot water tap in the kitchen I get rewarded with hot water within seconds. For years every time I did the dishes or turned on the kitchen sink it took about a minute and a half of cold water to get hot water. With this unit I have hot water within seconds and it is so cool to have hot water that quickly. I think this unit is awesome. And very easy to install. I just ran a flex line from my hot water fitting under the sink to the unit and then ran another flex line from the unit up to my tap.And the unit just slid in under my sink, set the temperature where you want it and you’re done.

SpinnerSpinner: The media could not be loaded.  My wife and I moved into a new house where the kitchen sink is as far removed from the hot water heater as is physically possible. It took about 2 minutes for hot water to arrive from the 70 ft distance. Since the water lines run in a concrete slab, even after hot water arrived, a slight pause in flow had a great cooling effect. This water heater tank arrived yesterday in the afternoon and we had hot water at the sink before dinner. Plumbing install was a breeze with the PEX lines. The time consuming portion was installing a new receptacle under the sink. With only a day or so of operation, we are ecstatic. Hot water flows within seconds as the attached video shows. I have a reminder to check the anode after 6 months to see how much erosion occurs. Just waiting for an inline valve to arrive and install as per recommended instructions.

Shut off valve added and everything is still good. We love this addition to our life.

Ryan G: Easy to install, perfect for what we needed. Only reason for 4 start and a recommendation to the manufacturerer, is to provide the 1/2 FPT fitting to connect to the waterlines. Even if it was a standard 1/2" Pex or Sharkbite. Sourcing the fitting took two additional weeks with an incorrect shipped item from Amazon and and few different stores to source.

Otherwise this tanks is awesome. Easy to hang and literally plug and play (if you source the waterline fittings).

CarefulPurchaser12: This 4 gallon mini-tank heater is perfect for my kitchen. The total cost for the tank and the installation was about $325.00—higher in my case because the tank did not quite fit under the sink and I had to move it to a cabinet 6 feet away, on the other side of the dishwasher. This added the cost of two 6 foot hoses, two brass connectors, and a 12 guage extension cord. The normal cost would be under $300.

I opted to abandon the hot water at the sink and run only cold water into the mini-tank. This way, running hot water in the sink never impacts my gas water heater. The downside is that I can run out of hot water at the sink, if I use too much at once, but the upside is that it saves a lot more energy and water. By turning up the temperature on the Bosch to ¾, I have eliminated the chance of running out for my own needs.

My sink is located about 30 feet from my water heater, which is actually more like 40’ of piping. It was taking a good 30 seconds to get hot water every time, and I started collecting the 2 gallons of wasted cold water for my outdoor garden.

Now the hot is basically instant. Because of the unusual 6’ distance, it takes one second to get...
