This paper deals with the review on performance improvement of the helical coiled tube with parallel and counter flow configuration of various correlations with specific data. The readings of mass flow rate and temperature difference of hot water fluid are recorded. Logarithmic Mean Temperature Difference LMTD, capacity ratio, universal heat transfer coefficient and effectiveness are calculated and compared for Parallel flow and Counter flow configuration with variations of coil configurations. By taking the reference of designing helical coil tubes will design the double pipe helical coils and experimental set up also has to prepare as per TEMA guidelines. The increased in the intensity of secondary’s flow developed due to centrifugal force due to curvature of the pipes.
