ABSTRACT:
An electric fluid heating apparatus include a number of electrically conductive pipe coils arranged side by side in parallel and connected to and extending between inlet and outlet pipes for flowing the fluid to be heated from the inlet pipe to the outlet pipe. Each pipe coil is disposed in a vertical plane and comprises a plurality of vertically extending laterally spaced pipe sections joined by U-bends at the top and bottom to form a single continuous serpentine coil. The central electrical points of the pipe coils are electrically connected to the phases of a polyphase alternating current source in a repetitive order and means associated with the ends of each pipe coil completes the circuit to the respective phases whereby the coils are resistively heated by the current flowing therethrough.
