    摘要： The invention relates to an apparatus (1) and method for heating a liquid, such as water, flowing into and through said apparatus (1) from an associated liquid source. The apparatus comprises a burner unit (60) and a coil (5) arranged in an internal housing (30), said internal housing (30) arranged inside an external housing (40) dimensioned so as to form a liquid reservoir (50) in between said two housings (30, 40) and wherein said burner unit (60) is arranged so as to direct a flame towards said coil (5). The liquid flows into the apparatus through a liquid inlet into said liquid reservoir (50) and from said liquid reservoir (50) through the coil (5) from a coil inlet to a coil outlet, and wherein the coil (5) and internal housing (30) are arranged so as to direct the flame from the burner unit (60) through a tortuous path ensuring a high energy transfer from said flame to said liquid. This design is advantageous for integration of the apparatus into a compact device, since the cool water surrounds the hot internal part of the apparatus. Thus, the external surface of the apparatus is cool enough to allow sensitive components to be placed close to the external housing (40), and at the same time, the apparatus provide a high energy efficiency.
