Flexible Electrode Heating System for Single-Phase Installations
 
7 Power Levels Without Electronics
 
GAZDA Trio 7 kW is a modular electrode heating system consisting of three boilers with stepped power configuration (1+2+4 kW).
This system allows you to adjust heating power by simply switching individual boilers on or off — without electronic controllers, inverters, or complex setup.
You get up to 7 power levels depending on the combination used, making the system highly flexible and energy-efficient.
Unlike traditional electrode boilers, where power depends heavily on water conductivity, the Trio system allows you to adapt the power output by selecting the right combination of boilers. No constant water adjustment is required.

How the GAZDA Trio System Works
The GAZDA Trio system is not a single boiler — it is a combination of three electrode boilers with different power levels.
Each boiler can operate independently or together with others. By switching them on or off, you can adjust the total heating power step by step.
Available power levels:
1 kW → 2 kW → 3 kW → 4 kW → 5 kW → 6 kW → 7 kW
No electronics, no programming, no complicated configuration.
In traditional systems, power strongly depends on water conductivity. If the water is too soft or too hard, performance can change significantly.
 
The Trio system solves this differently:
Instead of adjusting the water, you adjust the active electrode surface by switching boilers.
This ensures:
– stable operation with different water types  
– no need for constant water correction  
– simple and reliable control  
The result is a heating system that adapts to your installation without complexity.

Installation and Configuration
The system is mounted on a polypropylene manifold (32 mm) with standard 1” threaded connections for supply and return.
Each boiler is equipped with individual shut-off valves on both inlet and outlet. This allows any unit to be isolated or removed without draining the entire system.
A built-in sensor port is located on the top manifold for temperature control.
The unit is designed for wall mounting and weighs approximately 9 kg.

IMPORTANT
This product is a basic heating module and requires additional external components.
Not included:
– circulation pump  
– safety group (pressure relief valve, air vent, manometer)  
– expansion tank  
– filter  
All components must be installed separately according to your system design.

Compatibility
The system can be used with:
– mechanical thermostat  
– GAZDA G105 controller  
– Wi-Fi thermostat Konlen (Tuya / Smart Life)
All electrical connections must be performed by a qualified electrician.

Applications
– single-phase installations  
– systems with unstable or unknown water conductivity  
– users who need simple and reliable power control without electronics
