Single-phase solution for homes without 400 V connection

Designed for users who do not have access to three-phase power but still need an efficient electric heating system.

Works on standard 230 V installation without complex electrical requirements.
 
This version is adapted for single-phase operation while maintaining the core advantages of electrode heating: fast response, simple construction, and efficient heat generation directly through the heating medium (water).
The boiler is suitable for small houses, apartments, and installations where three-phase (400 V) power is not available.
Main Description:
The GAZDA R Series 3 kW single-phase electrode boiler is a compact heating solution designed for systems powered by standard 230 V supply.
It operates using direct electrical energy conversion into heat through the heating medium (water), ensuring fast heating response and stable performance.
The boiler housing is electrically insulated, allowing safe operation in properly installed systems, including those equipped with residual current protection (RCD).
The system works with standard tap water (recommended conductivity: 200–300 µS/cm), and in most cases no additional water preparation is required.

Built-in digital power and energy meter
This version of the boiler is equipped with a built-in digital meter that displays key operating parameters in real time:
🔴 Current (A) – shows the actual load
🟢 Power (kW) – calculated automatically
🔵 Energy consumption (kWh) – total electricity usage
⚡ Voltage (V) – network monitoring
This allows you to:
monitor boiler operation without external measuring devices
quickly verify correct system performance
track real energy consumption
👉 All key parameters are available instantly without the need for external ammeters or energy meters.
 
Single-phase load distribution (230 V)
 
In this version, the boiler operates using a distributed load system:
Total power of 3 kW is divided into 3 stages of approx. 1 kW each
Each stage draws about 4–4.5 A
Total current is approximately 13–14 A
The control box includes:
three single-pole circuit breakers
each stage is protected separately
stages are switched sequentially
This design allows:
reduced load on the electrical network
stable operation in single-phase systems
compatibility with standard household wiring
