An electrode boiler comprising a container for containing water and electrodes within the container which serve to pass electrical current through such water and which are generally upright when in use. Feed and drain systems are connected to the container to enable water to be fed to and drained therefrom. An outlet is provided through which steam generated inside the container can pass. An electrode current indicator provides an indication of the value of the electrical current passing through the electrodes. A controlling computer is connected to the feed and drain systems and the electrode current indicator. The controlling computer is set so as to cause the feed means to open when a predetermined drop in the electrode current has occurred owing to a boiling away of water from the boiler, and then to cause the feed system to close when a predetermined increase in the electrode current has occurred owing to the introduction of water into the boiler. Current-increase- rate measuring devices provided in the controlling computer to provide a measure of the rate of increase of electrode current when the feed system is opened. The controlling computer is to open the drain system for a drain period, in dependence upon the measured value of the current-increase-rate.
