The Bosch Tronic 1001 TR1001TF 300 T electric water heater, reference 7736506480, is a large-capacity domestic hot water storage tank designed for installations with high DHW demand. It offers 300 liters of usable capacity, a 3 kW electric heating element, and vertical floor-standing installation.
Its vitrified steel tank, high-capacity thermal insulation, and 469 liters of hot water available at 40 °C make it an especially suitable solution for installations where a significant DHW reserve is required. It operates on single-phase 230 volts, supports a maximum pressure of 8 bar, and includes a safety valve and dielectric unions.
The TR1001TF 300 T belongs to the Bosch Tronic 1001/2000 range of large-capacity electric water heaters. Bosch offers this family for installations where hot water consumption requires a larger storage volume than usual.
The 300-liter version is specifically designed for vertical floor-standing installation, unlike the 150 and 200-liter models in the same range, which are intended for wall mounting.
The tank provides a usable capacity of 300 liters, allowing a considerable volume of hot water to be stored and available when needed.
As a storage water heater, the water is heated in advance inside the tank by an electric heating element and is then available for later use in the domestic hot water system.
Bosch states a domestic hot water availability of 469 liters at 40 degrees Celsius. This value takes into account the mixing of the water stored at a higher temperature with cold water until the indicated use temperature is reached.
This mixed water volume provides a more realistic assessment of the unit’s DHW availability than considering only the physical 300-liter capacity of the storage tank.
The Bosch TR1001TF 300 T incorporates an electrical power rating of 3 kilowatts for heating the stored water.
The electrical installation must be sized according to the appliance power, circuit length, installation conditions, and applicable electrical regulations.
For a temperature increase of 50 degrees Celsius, Bosch states a heating time of approximately 5 hours and 53 minutes.
The actual time may vary depending on the initial water temperature, the selected temperature, the supply voltage, and the DHW consumption during the heating process.
The inner storage tank is made of vitrified steel. The vitrification creates a protective surface between the stored water and the steel tank, forming part of the tank’s protection system against the usual operating conditions in domestic hot water installations.
Bosch highlights the high insulating capacity of the large-capacity Tronic range. The insulation around the tank helps reduce thermal losses from the stored water once the selected temperature has been reached.
In a 300-liter storage water heater, good insulation is especially important to preserve thermal energy during periods when there is no DHW consumption.
The TR1001TF 300 T must be installed in a vertical position and floor-standing. This configuration is adapted to the volume and weight of the storage tank.
The installation site must provide a stable base capable of supporting the weight of the water heater when fully filled, which can reach approximately 360 kilograms.
The storage tank has a vertical cylindrical format with the following main dimensions:
Before installation, it is advisable to check both the available space and the access required to bring the unit to its final location.
The manufacturer specifies a maximum permitted pressure of 8 bar for the storage tank.
The hydraulic installation must be carried out in compliance with this limit and using the safety and protection components required by the manufacturer and by the installation regulations.
The range is supplied with a safety valve, an essential component to protect the storage tank against pressure increases associated with water heating and expansion.
The valve discharge must be installed according to the manufacturer’s instructions so that it can safely release water when necessary.
Bosch includes dielectric unions for the hydraulic connections. These components help electrically isolate different metallic materials in the water heater connection to the installation.
Their installation must follow the instructions supplied with the unit to keep the hydraulic connections properly protected.
The water connections of the Bosch TR1001TF 300 T are 3/4 inch.
Bosch technical documentation indicates a temperature value of 71 degrees Celsius for this 300-liter version.
The use temperature at the draw-off points can be adjusted or mixed through the corresponding components of the DHW installation.
The water heater has an IP24 protection rating, according to the manufacturer’s technical specification.
The location and electrical connection must be carried out in compliance with the protection zones and regulatory requirements applicable to electrical installations in the presence of water.
The Bosch Tronic 1001 TR1001TF 300 T has energy efficiency class C within the scale indicated by the manufacturer.
The load profile L identifies the category used to assess the energy performance of the unit under the corresponding standardized procedure.
With its 300 liters of storage, the TR1001TF is especially suited to installations where there is significant hot water demand and a large reserve is desired before a new full heating cycle is needed.
Electric water heater sizing should take into account the number of users, consumption habits, the number of draw-off points, and the electrical availability of the installation.
The Bosch Tronic 1001 TR1001TF 300 T 7736506480 combines 300 liters of usable capacity with 3 kilowatts of electrical power and up to 469 liters of DHW available at 40 degrees Celsius, providing a high hot water reserve for installations with significant demand.
Its vitrified steel tank, thermal insulation, vertical floor-standing installation, 3/4-inch connections, and included hydraulic safety components offer a complete solution for projects requiring a large-capacity electric water heater.
