We study the heat flow from an open, bounded set D in $\R^2$ with a polygonal boundary ∂D. The initial condition is the indicator function of D. A Dirichlet 0 boundary condition has been imposed on some but not all of the edges of ∂D. We calculate the heat content of D in $\R^2$ at t up to an exponentially small remainder as t↓0.
