Bosch US12 Tronic 3000 Review

Most people have heard of Bosch, considering they are a global leader of electronics and engineering. They have produced many household appliances and machines, some of which may be in your own kitchen or bathroom.

Today we will be reviewing one of their electric tankless water heaters in our Bosch US12 Tronic 3000 review. While this type of water heater is gaining popularity in North America, it is already widely used in Asia and Europe.

Using an electric on-demand water heater is especially useful in situations where installing new water pipes would be a problem or too costly. We invite you to take a look at our review to learn where and how this unit can be used, what to expect from this heater and more.

Bosch US12 Tronic 3000 Specifications

The compact water heater we have here fits into many tight spaces, including inside cabinets or under any sink. Because of its efficient dimensions (12.2 x 3 x 6.5 inches), it fits well into snug spaces.  Also, its weight of only 6 pounds makes it very easy to mount anywhere. Following the installation guide is pretty simple, and shouldn’t prove to be a challenge for most people.

For proper use, the manufacturer recommends using this model as a point-of-use heater, to be installed close to the fixture where hot water is needed. In a warm climate, this unit could support 2 faucets at the same time. At a temperature rise of around 35°F, you can achieve a flow rate of 2.3GPM.

Up to a single showerhead can be covered with this unit. You can hook up both a sink and a shower, but using the fixtures at the same time would probably result in lukewarm water, as it did for us. The power supply requirements for the heater is 12kW at 240V and a single 50-amp breaker is needed to protect the unit and circuit.

Customer Support and Warranty

Being such a well-known company, Bosch has a well-developed customer service department and provides a good user manual for US12 Tronic.  Consumers have reported that customer service branches in some cities are better than others, but in general they are helpful.

As long as the unit is maintained by the standards stated in the warranty policy, the heat exchange tube has a 5-year limited-warranty covering for leaks or manufacturing defects. The other parts have a 1-year limited warranty from the day of purchase.

What to Expect from Bosch US12 Tronic 3000?

Because of the slim design of this electric on-demand water heater, there are certain limitations for this unit.  It can’t fully support two fixtures at the same time unless you live in an area that has a groundwater temperature of 80°F (26.6°C) or higher. While you lose out on power, you get an exceedingly small water heater that can be placed anywhere, even right under the sink.

Since the unit has a 98% energy efficiency rating, it will provide savings on the electric bill, while giving continuous hot water. Because of the design and size, you can expect there to be very little maintenance involved with this machine.

Pros

• Very compact design makes it easy to install anywhere
• Easy installation process
• Sturdy construction, designed to prevent leaks

Cons

• 1-year limited warranty on the parts
• Low flow rate means it can only support one fixture at a time

Wrap-Up

With tankless water heaters of this size, you can expect limited but dependable service.  These may not be the most powerful units, however, they work well as single point-of-use providers. Whether you need to simply upgrade your existing system or you are planning on adding fixtures that need independent support, this little tankless water heater is an effective and discrete solution. If you are looking for something with a stronger rate of water flow, that can support multiple fixtures at once, then you will need something else.
