Description

The Bosch Tronic TR4000C-6 Electric Tankless Water Heater, part number 7738007416, is a 6.5-kilowatt point-of-use electric tankless water heater designed to deliver a continuous on-demand supply of hot water at a single sink across a wide range of residential, commercial, and mobile applications including residential sinks, apartments, RVs, mobile homes, boats, garages, warehouses, factories, stores, offices, restaurants, and hotels.

The TR4000C-6 features a solid copper heat exchanger with copper-sheathed elements housed in a compact and lightweight tough plastic enclosure weighing 3.4 pounds. The unit operates at 6.5 kilowatts on a 240-volt supply using a single-pole 30-amp double-pole breaker with 10 AWG wiring, operates at 98% efficiency with no standby heat loss, and features an outlet temperature control and operating indicator light on the housing. The unit activates at a minimum flow rate of 0.55 gallons per minute and connects to the water supply via ½-inch NPT fittings, with the cold water inlet at the bottom left and the hot water outlet at the bottom right.

What's Included: Bosch Tronic TR4000C-6 electric tankless water heater unit with mounting hardware. A dedicated 240-volt double-pole 30-amp hardwired circuit using 10 AWG wire and all plumbing connections are not included and must be provided as part of the installation by a licensed electrician and plumber.

Installation Limits: The TR4000C-6 requires a dedicated 240-volt double-pole 30-amp hardwired circuit wired with 10 AWG wire and must be installed by a licensed electrician in accordance with applicable local electrical and plumbing codes. The unit does not plug into a standard outlet.

Working water pressure must be maintained between 7 and 115 psi. The TR4000C-6 serves one sink at a time and is not designed for simultaneous multi-fixture hot water delivery. Hot water output temperature is dependent on incoming cold water temperature — lower incoming water temperatures reduce the achievable output temperature at a given flow rate.

Compatibility: The Bosch Tronic TR4000C-6 (part number 7738007416) is a close functional replacement for the Bosch Tronic 3000 US7, the Powerstream Pro RP7P, the Powerstream RP7, and the PowerStar AE7.2. The companion model in the Tronic 4000C series available at RuralEnergy.com is the TR4000C-3 (part number 7738007415).

Customers replacing a prior-generation unit must note that the cold water inlet on the TR4000C-6 is located at the bottom left and the hot water outlet is at the bottom right, which is reversed from legacy models — plumbing connections must be verified and adjusted accordingly during installation.

Product FAQ

What does the Bosch Tronic TR4000C-6 deliver at the point of use?

The Bosch Tronic TR4000C-6 delivers a continuous on-demand supply of hot water at one sink at a time without a storage tank, operating at 98% efficiency with no standby heat loss. Because it heats water only at the moment of use, there is no tank capacity limit on the duration of the hot water supply during a draw. The TR4000C-6 is suited for residential sinks, RVs, mobile homes, boats, apartments, garages, warehouses, factories, stores, offices, restaurants, and hotels where a compact, flexible, and efficient point-of-use hot water solution is needed at a single sink location.

What electrical supply does the Bosch Tronic TR4000C-6 require?

The TR4000C-6 requires a dedicated 240-volt double-pole 30-amp hardwired circuit using 10 AWG wire. The unit does not plug into a standard household outlet and must be hardwired by a licensed electrician at the installation location. The double-pole 30-amp breaker and 10 AWG wire requirement must be met regardless of the specific installation application. Customers should confirm the availability of a 240-volt circuit at the installation location before ordering and should note that the TR4000C-6 electrical requirement differs from the companion TR4000C-3, which operates on 110 or 120 volts with a single-pole 30-amp breaker.

What legacy Bosch units does the TR4000C-6 replace?

The Bosch Tronic TR4000C-6 is a close functional replacement for the Bosch Tronic 3000 US7, the Powerstream Pro RP7P, the Powerstream RP7, and the PowerStar AE7.2. The TR4000C-6 delivers comparable output capacity in the same point-of-use single-sink role as these legacy models. Customers replacing one of these units must note that the connection orientation on the TR4000C-6 is reversed from the legacy models — the cold water inlet is at the bottom left and the hot water outlet is at the bottom right — and plumbing adjustments must be planned and executed before installation is completed.

What is the difference between the Bosch TR4000C-6 and the TR4000C-3 available at RuralEnergy.com?

The TR4000C-6 and TR4000C-3 are both point-of-use electric tankless water heaters in the Bosch Tronic 4000C series available at RuralEnergy.com. The TR4000C-6 operates at 6.5 kilowatts on 240 volts with a double-pole 30-amp breaker, while the TR4000C-3 operates at 3.5 kilowatts on 110 or 120 volts with a single-pole 30-amp breaker. The higher kilowatt output of the TR4000C-6 allows it to achieve greater temperature rise at a given flow rate, making it better suited for installations in colder climates where incoming water temperatures are lower and a higher heating capacity is needed to reach the desired output temperature.

What are the water pressure and flow requirements for the Bosch TR4000C-6?

The TR4000C-6 requires a working water supply pressure between 7 and 115 psi and activates once water flow reaches the minimum threshold of 0.55 gallons per minute. Water pressure below 7 psi may prevent the unit from activating reliably. Water pressure above 115 psi must be reduced with a pressure reducing valve installed upstream of the unit before connection. The unit connects to the water supply via ½-inch NPT fittings with the cold inlet at the bottom left and the hot outlet at the bottom right.

Does the Bosch TR4000C-6 require any venting or maintenance?

The TR4000C-6 is an electric tankless water heater and requires no venting of any kind, as there are no combustion gases produced during operation. Because the unit heats water on demand with no storage tank, there is no anode rod to inspect or replace and no tank to drain or flush on a routine schedule. Maintenance requirements are minimal — periodic inspection of the water inlet filter screen to clear any sediment buildup is the primary recommended maintenance task for the unit over its service life.
