A formula for calculating the potential diffusivity 
of energy in porous solid bodies has been obtained, which made it 
possible to express the velocity of propagation of the energy field 
in the form of a relation of the type of an equation of heat conduction 
with a constant coefficient. Under the same boundary conditions, the 
velocity of propagation of the energy field is intermediate in value 
between the velocities of propagation of the temperature and concentration 
fields.
