We study a heat transfer equation in spatial dimensions n = 1, 2, and 3. A group classification with respect to the functional parameter k = k(T) is done and symmetry algebras are presented. Recursion operators are found in the case n = 1 and infinite hierarchies of symmetries are constructed. We also find a number of exact solution in all the three cases.
