A method of and apparatus for heating liquids such as water utilizing microwave energy is disclosed. A microwave fluid heater system comprising a microwave-transparent fluid conductor body is arranged in a microwave-reflective and heat-insulated chamber. The conductor body is provided with a plurality of passages through which the fluid to be heated flows. At least one microwave source is arranged in one wall of the microwave chamber to radiate the fluid conductor body so that fluid passing through the passages in the body is heated primarily by absorption of microwave energy. A water distribution system for a building is also disclosed in which a plurality of microwave fluid heaters are arranged at different locations, each heater being adapted to supply hot or cold water independently of the other heaters.

Apparatus for heating fluid, especially water, utilizing microwave energy comprising: means for generating microwave energy; means for defining a microwave chamber for containing the microwave energy generated by said generating means; and means in said microwave chamber means for conducting the fluid to be heated through the microwave energy, said fluid conducting means comprising a solid unitary block formed of a substantially microwave-transparent material, said block having a plurality of fluid passages extending therethrough, said fluid flowing through said passages directly contacting the microwave-transparent material of the solid unitary block, said block further comprising a pair of end covers formed of a substantially microwave-transparent material and sealingly mounted to respective ends of said unitary block, each end cover having a cavity enclosing the ends of said fluid passages and a conduit extending into said cavity, the total cross-sectional flow area of said fluid passages being at least twice the cross-sectional flow area of each of said conduits whereby the flow velocity through said fluid passages is substantially less than the flow velocity through said conduits.
