Default Node Number And Results

ZenCef is on a distinguished road

I have a simple 3D steady state heat transfer problem. I dont use fluid, all cells are solid and i gave them convection BC. All methods are same and i only increase the node number to control the mesh independence. Solution is converged after 2 iteration but the results ( heat flux and temperature) are also increase with the node number. Results increment is too high (e.g. 6 C) for this simple problem. Could you help me, what is my mistake?

Best regards..
