In this paper, thermal and surface properties of silver and silver-graphene thin film heaters were investigated. Especially heat transfer ratios to a media from the heater surface (heat transfer gradient) were investigated. A novelty of the study is determine the velocity of energy transfer. Graphene increased the heat transfer gradient about five times. Silver nanoparticles and silver nano fiber are intensively researched materials to produce the heater, and graphene doped or stacked silver coatings are promising materials to be manufacture a heaters. Silver-graphene coating is preferred for relatively low voltage. In the paper, applied voltage was adjusted in the range of 0.15-0.70 V for silver-graphene, and 0.50-1.50 V used for silver coating. These values are very low voltage value against the literature. The heaters were deposited onto polyvinyl chloride by a thermionic vacuum arc (TVA) deposition system. The heaters were used to heat a calorimeter box and it was found that silver-graphene heaters are promising materials and transfer the heat energy to air was very fast against the silver coated sample. To investigate the surface properties of coated layers, field emission scanning electron microscopy (FESEM) images were obtained and the extended intersection regions (EIR) between the collapsed regions were detected. EIR has the crack, space and volumes. Two dimensional plates are observed in Ag-Gr coated surfaces. Cyclic-voltammetry and Tafel graphs were obtained for the coated samples. Corrosion years were calculated as 3.19 x 103 and 2.31 x 105 years for 1 mm corrosion layer. Finally, coated silver-graphene coating is promising material for the surface heating. It found that surface topography plays a key role in transferring the heat energy. As a result, Graphene doped Ag thin films are proper for the high performance heater design and heat energy transfer.
