Minimize Wait Time for Hot Water
Waiting for hot water at a sink located far from a primary heating source can be frustrating. Only having access to cold water from a sink is just not useful, and plumbing a hot water line to every sink in a home or business requires time and money. To get hot water where it’s needed, when it’s needed, a better solution is to use the Tronic 3000 T from Bosch: a point-of-use electric mini-tank heater. This heater can supplement a primary water heating source, or be used under a single sink. In fact, the Bosch Tronic 3000 T can be used for three different applications: as a sole water heating source for a single sink, as a supplement to an existing heater located far from the sink, and as a buffer installed in-line with tankless water heaters that experience intermittent cold water, also known as 'cold water sandwiching'. No matter the configuration, there’s minimal stand-by loss from this premium mini-tank water heater.

This 4 gallen mini tank heater fit under my sink with less than 1/10th of an inch to spare (see pictures)
Installation by a professional is recommended and mine cost about $250 (which seemed on the high side, but I just wanted to get it over with ) - he did a good job.
HOT water flows within 2 seconds and lasts for about 3 minutes before the cold water from the hot water gas heater cools it down a little bit. Warms up quickly again - within 10 minutes, but at that time the gas hot water heater already pumps hot water back into the tank - so almost continuous flow.
Hook it up from your hot water line into the cold water line of the tank, then the outlet goes to my dishwasher and the hot water faucet..
I recommend that you put a drip pan under it in case there is a slow leak. I got mine also on Amazon and it fits like a glove.
make sure you have a 110V outlet under the sink that is NOT switched with the garbage disposal. (-> lesson learned!) Cost me another $100 to get an electrician to run an extra line from the dishwasher.
Ensure that the total amp drawn from all appliances are not exceeding your breaker. Mine is borderline, but I never run all 3 at a time for long, so i am below the 20 Amp max my breaker can handle.
+ heats up water in less than 10 minutes (first fill)
+ continuous flow if you use the hot water line to fill it
+ 4 gallon tank on medium heat setting gives you 4-5 minutes of really hot water (hot enough so you can still touch it)
+ you can set the heater setting to hotter if needed, but that would burn your hand (did not perform temp reading, but trial and error until it was hot enough for me
- it is large and takes up most of my cabinet space, but - it is what it is!
- if you want it done right, then have a plumber install it
- make sure you have an outlet that is not switched by the garbage disposal (otherwise you have an issue as it would only turn on when you run the disposal) - but also not an issue of the product

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.
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.
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.
