Our boilers are designed to be integrated into heating systems - both individual and combination. They can be installed in parallel or in series with existing gas or solid fuel boilers and can also be used to heat water in indirect heating tanks. The boiler is designed to pass alternating current through the heat transfer medium between the electrodes, which converts the electrical energy into thermal energy. Particular attention must be paid to the electrical conductivity of the heat transfer medium for optimum boiler operation. It must be understood that issues relating to changes in electrical conductivity with an electrode boiler are not a problem if installed correctly. One solution is to install a heat exchanger in parallel with the electrode boiler or to connect a KROS seven-bridge thermostat which enables regulation of the current intensity when the electrode boiler is in operation. In this way, the influence of the conductivity of the water on the operation of the system is negligible.

Single-phase electrode boilers GAZDA are covered with polymer material on the outside. Thus, there is no metal conductive part that can be touched by a person when the boiler is switched on. And the boiler drum is not in any way in contact with walls and ground. In this regard, the boiler works perfectly well in the electrical network when the RCD is switched on. 

We are introducing a revolutionary innovation in electric heating - GAZDA R series boilers! These innovative devices solve the main problem of electrode boilers - incompatibility with RCD. Thanks to their fully plastic casing, R series boilers are safe, efficient, and easy to install. Models are available from 3 to 15 kW, suitable for any needs. To learn more about the advantages and features of these boilers, watch our new video. In it, we explain in detail the GAZDA R series technology and demonstrate why these boilers will be the perfect choice for your home.

    Electrode boilers possess a unique characteristic: they are often incompatible with Residual Current Devices (RCDs). This incompatibility arises from the operating principle of electrode boilers, where electric current passes through the heating medium (usually water). Additionally, the boiler's body is connected to both the grounding and neutral wires. An RCD may interpret this configuration as a current leakage, causing it to trip when the boiler is activated.

    To address this issue in three-phase networks with RCDs, we offer the following solution: purchase three single-phase GAZDA KE series boilers. These can be connected in parallel or cascaded in the heating system. Then, connect these three boilers to the three-phase network, ensuring each boiler is connected to a separate phase. The neutral or "zero" wire will be shared among the three boilers.

    Our classic three-phase electrode boilers, GAZDA BE series, remain a popular choice due to their reliability and affordable price. They are particularly in demand for capacities over 15 kW, including models of 18, 25, 36, and 50 kW, which are ideal for heating large areas or commercial facilities.

    For those seeking a solution fully compatible with RCDs, we also offer innovative GAZDA R series boilers with capacities up to 15 kW. These boilers with fully plastic casings ensure safe and efficient operation in networks with RCDs without additional modifications.

    Regardless of whether you choose our classic BE models, single-phase KE boilers, or the innovative R series, GAZDA guarantees efficient and reliable heating for your home or business.
