Moderner Drehstrom-Elektrodenkessel – 3 kW (R-Serie)
 
GAZDA R 3-3 is a compact Drehstrom-Elektrodenkessel designed for closed heating systems and sicherer Betrieb mit residual current protection (RCD).
 
The boiler housing is plastic-coated, providing electrical insulation and allowing safe installation in systems equipped mit an RCD.
 
It operates on standard tap water (recommended conductivity: 200–300 µS/cm). In most installations, no water adjustment is required.
 
The boiler converts electrical energy directly into heat through the heating medium (water), ensuring fast response and stable power output.
