The Bosch Tronic 1001/2000 vertical electric water heater with 150 liters, reference 7736506470, is designed to produce and store domestic hot water in homes and other installations with high demand. The TR1001T 150 B model includes a 2.2 kW electric heating element, vitrified steel tank, high-density thermal insulation, and a magnesium anode to protect the tank against corrosion.
Its 150-liter capacity and availability of up to 259 liters of mixed water at 40 degrees Celsius provide a significant hot water reserve. It is designed for vertical wall installation and, with an optional accessory, can also be installed floor-standing.
Reference 7736506470 belongs to the Bosch Tronic 1001/2000 range, intended for installations that require a high storage capacity for domestic hot water.
The tank has a nominal capacity of 150 liters. Bosch states an approximate usable capacity of 151 liters and an availability of 259 liters of mixed water at 40 degrees Celsius under the conditions established for energy measurement.
This capacity makes it possible to store hot water in advance so it is available when demand increases, avoiding the need to produce the full flow instantaneously.
The Bosch Tronic TR1001T 150 B incorporates a 2,200-watt electric heating element responsible for heating the water stored in the tank.
The unit operates with single-phase power supply of 220 to 240 volts and a frequency of 50 or 60 hertz. The nominal electrical current indicated by Bosch is 9.6 amperes.
For a temperature increase of 50 degrees Celsius, Bosch specifies a heating time of approximately 4 hours and 16 minutes. This also corresponds to around 256 minutes to heat the water from approximately 10 to 60 degrees Celsius.
The actual time may vary depending on the initial water temperature, supply voltage, ambient conditions, and consumption during heating.
The inner tank is made of high-strength vitrified steel. The coating protects the metal surface that remains in continuous contact with domestic water and is specifically designed for this type of storage heater.
To maintain its performance, it is important to carry out the periodic maintenance operations indicated by Bosch, especially checking the anode and cleaning the tank when water conditions make it necessary.
The water heater incorporates a magnesium protection anode that acts as an additional protective element against tank corrosion.
The anode is a wear component and must be checked periodically during maintenance. Its service life depends, among other factors, on the chemical characteristics and hardness of the installation water.
Between the tank and the outer casing, a layer of 30-millimeter high-density polyurethane foam is incorporated.
This insulation limits heat losses from the stored water and helps maintain the temperature for longer once the heating cycle has finished.
The technical documentation indicates a thermal loss through the casing of approximately 1.60 kWh every 24 hours. The product’s commercial energy information also declares a service availability loss of approximately 1.98 kWh per day, according to the corresponding test method.
The Tronic 1001/2000 range allows water temperature adjustment. For the 150- and 200-liter models, Bosch indicates temperature control up to approximately 65 degrees Celsius.
The energy documentation for reference 7736506470 sets a supply temperature of approximately 66 degrees Celsius.
The appliance also includes a safety thermostat that cuts off the electrical supply if the temperature exceeds the safety limit set by the manufacturer.
The 150-liter model is primarily designed for a vertical wall-mounted installation. Bosch indicates that the two support bars and suitable fixing elements must be used to safely support the weight of the fully filled water heater.
The empty unit weighs approximately 34 kilograms and can reach approximately 184 kilograms when the tank is full, so the strength of the wall and fixing system must be checked before installation.
For the 150- and 200-liter models, Bosch offers an optional four-leg accessory for floor-standing installation. This support is not supplied as standard with the water heater.
The possibility of mounting on a stand expands installation options when the available wall is not suitable for supporting the weight of the storage heater.
These dimensions should be taken into account both when selecting the installation area and when leaving enough space for hydraulic connections, access to components, and future maintenance operations.
The water connections of the storage heater are 3/4 inch. The unit is designed to be connected to a pressurized domestic hot water system and must include the corresponding hydraulic safety components.
Bosch specifies a maximum operating pressure of 8 bar. When the supply pressure of the installation exceeds the limits indicated in the manual, the corresponding pressure reduction system must be installed.
The installation must include a suitable safety device for domestic hot water. The manual specifies a safety valve set to 8 bar and a 3/4-inch connection in accordance with the applicable requirements.
The valve should be checked periodically to prevent blockages caused by limescale deposits and to ensure proper operation.
The water heater has an IP25 protection rating according to EN 60529 and an electrical protection class I.
The electrical installation must include grounding and the corresponding disconnecting and residual-current protection devices according to the applicable installation standards.
The Bosch Tronic 1001/2000 is specifically designed to heat and store potable water within pressurized sanitary installations.
Its 150-liter storage capacity makes it especially suitable for homes and applications where hot water demand exceeds the capacity of compact electric water heaters.
Reference 7736506470 has an energy efficiency class C for water heating and a declared M load profile.
According to the official energy information:
The declared energy consumption values come from standardized tests and are mainly used to compare appliances under the same reference conditions. Actual consumption will depend on usage, selected temperature, and installation conditions.
Although the tank stores approximately 150 liters, the energy label declares up to 259 liters of mixed water at 40 degrees Celsius.
This value takes into account the mixing of the stored hot water with cold water until a usable temperature of 40 degrees Celsius is reached, so it better represents the amount available for certain sanitary applications than the physical tank capacity alone.
Periodic maintenance is important to preserve the performance and service life of the storage heater. Bosch specifically includes checking the following components:
The inspection frequency may vary depending on water quality and hardness. Limescale buildup on the heating element can increase energy consumption, lengthen heating times, and reduce component service life.
The Bosch Tronic 1001/2000 150 liters 7736506470 combines a large-capacity tank with a 2.2 kW heating element, vitrified tank, polyurethane insulation, and magnesium anode protection.
Its vertical installation, availability of up to 259 liters of mixed water at 40 degrees Celsius, temperature adjustment, and the option to use an optional floor stand make it a practical solution for homes and installations that need a high reserve of domestic hot water.
