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.

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.
First review after 2 days was 5 stars: I don't know why anyone would need a 4-gallon tank. This one at 2.5 works great. The dishwasher needs only 1.9 gallons. My plumber added a two-way valve (not included) out the top so that it could supply my hot water faucet and the dishwasher. Very pleased with it. So nice to have instant hot water instead of wasting water down the drain until it gets hot.
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.
