An electrical liquid heating system and method of heating a liquid includes providing at least two spaced apart electrical conductors and applying an electrical energy source to the conductors. A liquid is directed into contact with the conductors thereby delivering electrical energy to the liquid. Electrical energy is delivered to the liquid at a power level that is sufficient to generate an electrical current to produce resistive heating of the liquid. The electrical energy may be delivered to the liquid at a power level that is sufficient to break at least some molecular bonds of molecules defining the liquid. A regulator may be provided for regulating delivery of electrical energy to the liquid.
