The article presents studies of nano-modified heat-accumulating materials controlled by a magnetic field. Paraffin is used as a material with the effect of energy accumulation in the phase transition. Carbon nanotubes are used to modify paraffin. For the synthesis of carbon nanotubes used catalyst Co-Mo/Al2O3-MgO. The synthesis process is based on the CVD method. The method of obtaining nanomodified paraffin with ferromagnetic properties is described. To impart paraffin ferromagnetic properties, a ferromagnetic powder previously ground with carbon nanotubes was introduced into it. Mechanical activation was used for the ferromagnetic powder, which provided particles with an average size of 5 ?m. The analysis of charge control regimes of a paraffin-based heat-accumulating material was carried out using a non-contact method for measuring the temperature field. For this purpose, the FLUKE Ti9 thermal imager with a 160 x 120 radiation detector and a matrix in the focal plane and a measurement range from -20 to +250? was used...
