Electric boiler Bosch Tronic Heat 3500 15 KW
Technical characteristics
Bosch Tronic Heat 3500 6 kW Electric Boiler – Efficient and Convenient Heating
Bosch Tronic Heat 3500 6 kW is a wall-mounted electric boiler equipped with an integrated expansion tank and a circulation pump with frequency control. It is designed for efficient heating of residential and commercial spaces up to 60 m² and can work in combination with an indirect heating boiler. The device is compatible with 220 V and 380 V electrical networks.
Key Features
Durable metal casing with protective powder coating to prevent corrosion.
Modern thermal insulation, reducing heat loss and noise levels during operation.
Modular heating system with independent heating elements that activate alternately, extending the boiler's service life and reducing energy consumption.
Three-speed circulation pump for even distribution of the heat carrier.
Standard Configuration
7-liter expansion tank
Automatic air vent, eliminating air locks in the system
Safety valve, preventing excessive pressure
Water pressure sensor for stable system operation
Temperature limiter, preventing equipment overheating
Protection Systems and Reliability
Frost protection function enabled by default, eliminating the need for additional settings.
Automatic pressure control: if it drops below 0.6 bar, the system blocks the boiler operation.
Intelligent Control System
Electronic controller automatically regulates power, ensuring smooth activation of the heating elements and optimizing energy consumption based on the heat carrier and ambient air temperature (if sensor available).
Connection options:
Room thermostat
Underfloor heating sensor
Extended functions module
Cascade connection for combining multiple boilers into a single system
