Most coronal heating studies focus on active regions (ARs), but the quiet diffuse corona is also subject to plasma heating process. Using differential emission measure tomography (DEMT) of time series of EUV image, in combination with potential extrapolations of the coronal magnetic field, it is possible to estimate the energy flux in the low corona required to maintain thermodynamically stable structures in the quiet sun (QS). We present results based on both EUVI/STEREO and AIA/SDO EUV data, and MDI/SOHO synoptic magnetograms. We show results for two solar Carrington rotations: CR-2081 (last solar minimum) and CR- 2099 (rising phase of solar cycle 24).
