Bosch Tronic 3000 Point-of-Use Electric Tankless Water Heaters

There are 5 different Bosch Tronic 3000 point of use electric tankless heaters, Models US12, US9, US7, US6 and the US3.  All models have different Kilowatt requirements and require specific breakers and wire gauge size.


Ultra compact and lightweight, these five point-of-use / under-sink tankless water heaters were designed to provide an endless supply of hot water for 1 kitchen and / or bathroom sink at a time in commercial and residential applications. Advantages include 99 % efficiency with minimal stand-by loss. Most models come equipped with high / low kW settings and universal horizontal / vertical mounting options.

The model Bosch Tronic 3000 US3 point of use electric tankless is the only unit that is 120V and is designed for low flow sinks in southern states where the incoming ground water is warmer so the temperature degree rise can be achieved by the 120V output where it will provide hotter water.  This unit is not recommended for the northern states where the incoming ground water is cooler as the unit only has the ability to use one setting as it only has one element inside the heating coil.


The model Bosch Tronic 3000 US6 point of use electric tankless is 277 volt, 6KW and gets hard wired in to a 25 amp breaker.  The US 6 is the direct replacement for the older Powerstream Pro RP2P.  The Bosch US 6 has a low/high switch that enables either 1 or 2 elements to be activated depending on the output temperature you are trying to achieve.  The US 6 is good for a point of use sink with lower flows. 

The model Bosch Tronic 3000 US7 point of use electric tankless is 240 volt, 7.2KW and gets hard wired in to a 30 amp breaker.  The US 7 is the direct replacement for the older Powerstream Pro RP7P.  The Bosch US 7 has a low/high switch that enables either 1 or 2 elements to be activated depending on the output temperature you are trying to achieve.  The US 7 is good for a point of use sink with lower flows. 

The model Bosch Tronic 3000 US9 point of use electric tankless is 240 volt, 9.5KW and gets hard wired in to a 40 amp Double Pole breaker.  The US9 is the direct replacement for the older Powerstream Pro RP1P.  The Bosch US 9 has a low/high switch that enables either 1 or 2 elements to be activated depending on the output temperature you are trying to achieve. The US 9 is good for a point of use sink/dishwasher or washing machine.

The model Bosch Tronic 3000 US12 point of use electric tankless is 240 volt, 12KW and gets hard wired in to a 50 amp Double Pole breaker.  The US12 is the direct replacement for the older Powerstream Pro RP12PT.  The US 12 is good for a point of use sink/dishwasher or washing machine.  The US 12 is thermostatically controlled.  This unit may also work for a low flow shower if installed in the southern states where the incoming ground water is warmer.
