Abstract
The present invention relates to a heating system for heating a fluid medium, said heating system comprises a carrier unit and a heating unit, with the carrier unit having a surface comprising at least a plane portion being at least substantially normal to a longitudinal axis and an at least part-circularly shaped groove extending from said carrier unit and wound about the longitudinal axis, and the heating unit having a heating element at least partially arranged in said groove of said carrier unit. In the inventive heating system, the groove extends at least partially helically about the longitudinal axis. The present invention further relates to a heated conveyor pump for conveying and heating a fluid medium, said pump comprises a drive unit, a pump housing and the inventive heating system. The heating system is coupled to the pump housing with the groove extending into the pump housing in a manner such that the size of the cross-section of the groove decreases in the flow direction of the conveyed fluid medium.
