Owner's Manual Tronic Point of Use

The Bosch Tronic 3000 is an ultra-compact and lightweight under-sink tankless water heater. It is designed to provide an endless supply of hot water to one or more sinks. The Tronic 3000 has a 98% efficiency with no stand-by loss and it is encased in a beautiful white durable plastic housing. This unit has the ability to be installed in a 360-degree orientation, which allows you to position the unit in tight under-counter applications which makes for an easy and flexible installation.

The Benefits of Tankless

The Tronic 3000 takes up far less space than a traditional water heater and can be wall-mounted right under the sink, taking up practically zero space. Because they run on electricity and don’t hold water, there is no venting and virtually no maintenance. With significant energy and space savings, this tankless water heater is a great choice for your point-of-use applications.
