Water heater OP-21.04 21 kW electric instantaneous - three-phase KASKADA2, multi-point, pressure 16587

Electric instantaneous water heater KASKADA2 21 kW

This three-phase, pressure water heater KASKADA2 with a power of 21 kW is an efficient solution for quickly heating water in homes and facilities. Designed to serve several hot water draw-off points, it will be suitable for both the kitchen, bathroom, and workshop. Its compact dimensions allow for installation both above and below the sink.

Heaters from the Kaskada 2 series are characterized by hydraulic control, which means that energy consumption automatically adjusts to the current demand for hot water. Two operating ranges allow you to optimize energy consumption depending on the season and the inflow water temperature. Range I is recommended in the summer, and range II in the winter.

Thanks to its construction and materials used, the heater ensures reliable operation and long life. It is a solid choice for people looking for an effective and economical way to access hot water.

Characteristic features and application

The OP-21.04 heater is a device designed for quick heating of utility water in systems with a central hot water source. Its three-phase power supply (400V) ensures stable operation even with high hot water consumption. The possibility of connecting to several draw-off points makes it an ideal solution for larger families or public utility facilities.

• Fast heating: Thanks to the high power of 21 kW, the heater provides almost instant access to hot water.
• Multi-point supply: Possibility of simultaneously supplying several hot water draw-off points (e.g. kitchen tap and shower).
• Hydraulic control: Automatic adjustment of heating power to the demand for hot water – energy saving!
• Two operating ranges: Optimization of energy consumption depending on the season and inflow water temperature.
• Compact dimensions: Allow installation in a limited space (height 460 mm, width 210 mm, depth 130 mm).
• Pressure system: Ensures stable water pressure regardless of the number of open taps.
• Safe use: The device has overheating protection and is adapted to work with water pressure from 0.2 to 0.6 MPa.

Installation and operating parameters

Installation of the KASKADA2 heater is relatively simple and can be performed by a qualified electrical and plumbing installer. It is important to ensure appropriate electrical protection (3x35A) and to supply water at a pressure of 0.2 - 0.6 MPa. The device is designed for wall mounting – both above and below the sink (requires additional accessories).

The use of thermal control ensures reliable operation of the device for a long time. The lack of a display or temperature indicator simplifies the operation of the device – everything is done automatically thanks to hydraulic control. The heater does not have a magnesium anode, which simplifies its maintenance. The cold water connection is an internal thread G 1/2".
