Its greatest advantage is the ability to choose power (15, 18, or 21 kW) during installation. This means it perfectly adapts to the capabilities of your electrical installation and your actual needs, making it ideal for simultaneous supply to multiple points (e.g., bathroom and kitchen).
The three-phase electronic instantaneous water heater Bosch Tronic 4001 (TR4001 15/18/21 EB) is the top and most reliable choice for abundant hot water usage, exactly when you need it. Designed with Bosch's German quality, it ensures absolute stability in water temperature, regardless of fluctuations in the water supply pressure.
3-in-1 Innovation
Its greatest advantage is the ability to choose power (15, 18, or 21 kW) during installation. This means it perfectly adapts to the capabilities of your electrical installation and your actual needs, making it ideal for simultaneous supply to multiple points (e.g., bathroom and kitchen).
Easy Installation & Economy
Thanks to the innovative CLICKFIX plus® mounting technology, installation is faster and easier than ever, saving time and money. Additionally, by operating only when you turn on the tap and heating exactly the amount of water that passes through it, it is classified in Energy Class A, eliminating unnecessary energy losses (compared to traditional water heaters with a tank).
Advantages & Applications
Absolute Stability: The electronic control compensates for fluctuations in water pressure, preventing annoying "cold-hot" changes during the shower.
Power Flexibility: No need to guess which device fits your power supply. The installer simply selects the appropriate power (15, 18, or 21 kW) internally.
Maximum Savings: Heats water instantly, only when you need it, offering up to 30% savings in electricity and water compared to hydraulic instantaneous water heaters.
Safe Installation: With an IP25 waterproof rating, it can be installed safely even inside the bathroom area (zone 1).
