A steam injection heater for liquids. The liquids are carried by a conduit characterized as having an upstream end, downstream, substantially circular cross-section and tapered section. A steam inlet pipe is caused to pass through a side wall of the conduit for injecting steam at its outlet proximate the longitudinal axis of the conduit upstream with the tapered section. The steam inlet pipe further includes a mixing element of a configuration to cause steam emanating from the steam inlet pipe to enter the conduit as a rotating cone of steam for efficiently transferring heat energy from the steam to the moving stream of liquids.
