Abstract
A heater for heating fluid is shown having a plurality of self-regulating electrical resistance heater elements 22 placed in electrically and thermally conductive relationship with heat transfer members 20, 120. The heat transfer members are each configured to form a plurality of fluid receiving channels so that when placed in a fluid stream heat generated by the heater elements will be dissipated to the fluid through the heat transfer members. Additionally, thermally conductive grease is used between the heater elements 22 and heat transfer member 20, 120 to better transfer the heat. The heater elements are arranged in groups with at least two heater elements in a group electrically connected in series and the groups electrically connected in parallel.
