The Bosch Tronic TR2000TF 500 B electric water heater, reference 7736506216, is a high-capacity electric storage water heater designed for installations with a high demand for domestic hot water. It features 500 liters of usable volume, a 6,000 W electric heating element and three-phase 400 V power supply, combining large storage capacity with a vitrified steel tank, magnesium anode protection and high-capacity thermal insulation.
Its design is prepared for vertical floor-standing installation, unlike lower-capacity models in the same family that can be wall-mounted. The Tronic TR2000TF 500 B includes manual temperature control, G 1" hydraulic connections, a safety valve and galvanic insulators included, making it a solution especially suitable when large amounts of stored DHW are required.
The Bosch Tronic TR2000TF 500 B belongs to the Tronic range designed for installations with high hot water consumption needs.
Its tank offers a usable storage volume of 500 liters, allowing for a considerable DHW reserve and serving high consumption or multiple draw-off points depending on the system sizing.
The official energy label also declares a mixed water volume at 40 °C (V40) of 761 liters, a value obtained under the standardized test conditions established for energy labeling.
The water heater incorporates a 6,000 W electric heating element to heat the stored water.
This high power output is sized for a 500-liter tank and allows for a declared heating time of approximately 4 hours and 50 minutes for a 50 °C temperature rise.
The actual time required to heat the water will depend on the initial temperature, selected temperature, ambient conditions and simultaneous consumption during the heating process.
Reference 7736506216 requires a 400 V, 50 Hz three-phase electrical supply.
Bosch technical documentation declares a nominal current of approximately 8.7 A per phase and a reference power cable cross-section of 2.5 mm².
Due to its power and three-phase supply, the electrical connection must be carried out by a qualified professional and the protections, conductor sizes and disconnecting devices must be dimensioned in accordance with the manufacturer’s manual and applicable electrical regulations.
The storage water heater is manufactured with a vitrified steel tank in accordance with Bosch specifications for potable water storage.
The vitrified coating protects the inner metal surface in contact with the water and forms part of the water heater’s corrosion protection system.
The Tronic TR2000TF 500 B incorporates a magnesium protection anode that complements the protection of the vitrified tank against corrosion.
The anode is a consumable component and must be inspected periodically during water heater maintenance. Its condition and replacement frequency depend, among other factors, on the quality and composition of the installation water.
The water heater uses CFC-free polyurethane thermal insulation to reduce heat losses from the stored water.
The technical documentation states an insulation thickness of approximately 49 mm and heat losses through the casing of 2.72 kWh every 24 hours.
Proper insulation helps keep the water temperature for longer and reduces the energy needed to compensate for heat losses when there is no consumption.
The Bosch Tronic TR2000TF 500 B features manual water temperature control.
The adjustment range specified in the manual is approximately 10 to 85 °C. The unit is factory-set with the control at 65 °C.
The selector is located at the lower part of the unit and allows the temperature to be increased or decreased according to usage needs.
In addition to the regulating thermostat, the unit includes a safety thermostat designed to protect the water heater in the event of abnormally high temperatures.
Correct installation of the electrical and hydraulic safety devices is essential to ensure proper operation.
The storage water heater is designed to withstand a maximum permissible potable water circuit pressure of 10 bar.
The installation must include the safety and pressure control elements indicated by Bosch, especially when mains pressure may reach high values.
The supply includes an 8 bar safety valve, intended to protect the storage water heater against excessive pressure increases during heating.
During normal operation, a small amount of water may be discharged through the valve as a result of thermal expansion of the water. The discharge outlet must be installed strictly following the manufacturer’s instructions.
Bosch also supplies two galvanic insulators for the hydraulic connections.
These elements help limit electrochemical phenomena between different materials in the installation and must be fitted following the instructions in the manual.
The cold water inlet and domestic hot water outlet use G 1" threaded connections.
The 500-liter model is specifically designed for a floor-standing vertical installation.
Due to its dimensions and weight, it must be placed on a strong, level surface capable of permanently supporting the load of the water heater when fully filled.
Bosch specifies an empty weight of approximately 160 kg and an approximate filled weight of 660 kg.
The current official documentation provides approximate external dimensions of 1,838 mm in height, 750 mm in width and 880 mm in depth.
The dimensional drawing in the manual shows a cylindrical body of approximately 756 mm in diameter and a maximum footprint dimension of around 879 mm due to elements protruding from the storage tank body.
These dimensions must be taken into account when planning access to the room, transport to the final location and the space required for subsequent maintenance operations.
According to the current official energy label, the TR2000TF 500 B has an XL load profile and an energy efficiency class C.
The declared ErP data are:
The water heater has an IPX4 protection rating and belongs to electrical protection class I.
The unit must be connected to earth and the electrical installation must include the protections and disconnecting devices required by the manufacturer and applicable regulations.
The Bosch Tronic TR2000TF 500 B has been specifically designed to heat and store potable water for DHW.
It must be installed in a pressurized sanitary system and following the manufacturer’s instructions for installation, commissioning and maintenance.
To keep the unit in good condition, Bosch provides for periodic inspection, cleaning and maintenance operations.
Components requiring special attention include the magnesium anode, safety valve, tank interior, heating element and thermal control and protection components.
The required frequency may vary depending on water quality, hardness, usual operating temperature and service conditions.
The Bosch Tronic TR2000TF 500 B stands out for its 500 liters of usable storage and 6 kW of electric power, offering a solution especially suited to installations that need a large reserve of domestic hot water.
Its vitrified tank, magnesium anode, thermal insulation, safety valve, G 1" connections and temperature adjustment between 10 and 85 °C bring together the elements needed for a high-capacity DHW installation, while its floor-standing design avoids the need for wall fixing to support the considerable weight of the storage water heater.
