Differential Equations & Applications, 2022 Summary: By means of fixed point theory we study properties of solutions of a Volterra integral heat equation \[ x(t) = a(t) -\int^t_0 A(t-s) f (s,x(s))ds \] by first mapping it into \[ x(t) = z(t) +\int^t_0R(t-s)\left[x(s)-\frac{f (s,x(s))}{J}\right]ds \] where \[ z(t) = a(t)-\int^t_0 R(t-s)a(s)ds, \] \(R\) is the resolvent of \(JA\), \(J\) is a large
