Heat exchanger liquid can be heated by pumping the pressurized liquid through multiple pin hole openings in partitions spaced along the flow conduit that contains the liquid. The pin holes in each partition exert a heating action on the flowing liquid by causing the liquid to have a high degree of boundary layer turbulence.
