Energy storage boiler medium

Electrode boilers and the energy transition

A traditional fired boiler needs a combustion chamber and a tube section to transfer heat from the flame to the water. This results in large, heavy and costly construction. In the electrode boiler heat is generated directly in the compact water volume between the electrodes. The electrode boiler uses medium voltage, in the range 6-24 kV.
