Abstract

A method and apparatus for preventing build-up of deposits on internal surfaces (6) of a water heater (1). A heat shock treatment is periodically applied to the surfaces (6) resulting in differential thermal expansion and/or contraction between the internal surfaces (6) and deposits (7) adhering thereto that causes the deposits (7) to crack and break away from the surfaces (6). The heat shock treatment may include the step of alternately heating and cooling the internal surfaces (6) in any order and may be repeated one or more times. The internal surfaces (6) may be low friction surfaces to reduce adhesion between the surfaces (6) and any deposits (7) that facilitates removal of the deposits (7) during the heat shock treatment.
