We study the order of numerical convergence of two nonlinear difference schemes proposed for solving the heat transfer equation in the P1-approximation. The first scheme is based on a sweep monotonic scheme with first-order invariants. The second scheme is built by TVD-reconstruction of the first scheme using a corresponding monotonic limiter and is formally considered to have the second order of approximation.

Keywords: heat transfer, TVD-scheme P1-approximation.
