A modular fountain assembly for controlling the temperature and flow of viscous fluid with a melting point between ambient and approximately 150 degrees Fahrenheit is disclosed. The modular assembly for controlling the heating and flow of fluid includes an enclosed controlling base and an upper recirculation module having a detachable lower basin, one or more modular tubular sections, a small high basin on top of the highest tubular section, an Archimedes screw of a set pitch dimension to facilitate the flow of the fluid from the lower reservoir to the small high reservoir atop the tubular section or sections, and a series of circular tiers atop each tubular section. The lower basin is attached to the controlling base using mechanical or electro mechanical support structures. The controlling base provides rotational force for the Archimedes screw at variable rotational speeds to drive the fluid upward within the modular tubes as well as a heating sub module. The lower basin has an upper bowl and a lower pool of fixed set depth with an opening to permit a drive shaft attach to the Archimedes screw. The circular base controls the temperature of the fluid using a temperature probe protruding from the lower base into the lower basin. The bottom modular tube attaches to one or more vertical support structures that extends from the controlling base thru the lower reservoir. The circular tiers are held stationary between modular tube sections or between the highest tubular section and the high basin.
