Abstract
Electrical oscillations are supplied to electrodes of a diathermal heating chamber. A liquid is passed through the diathermal heating chamber so as to be heated. The liquid has a minimum level of dissolved solids, which is replenished over time or when the dissolved solids in the liquid fall below a predetermined minimum level. Alternatively, when the level of dissolved solids is excessive, current input or liquid temperature is reduced.
