Abstract
We find a simple inflationary solution in an inhomogeneous spacetime with h eat flux. The heat flux obeys a causal transport equation, and counteracts the inflationary decrease of energy density. At late times, the heat flux t ends to zero and the fluid approaches the equation of state p = -rho.
