I have a HERMS system, so everything is at temp at the same time. But, what I did before when using a cooler..... if I needed to strike with 169F water, I would heat my water to 175F, dump it in the tun, leave the lid off and stir until it cooled to 169F. Then stir in the grains. I normally hit my temps dead on.
When I started mashing in a keg, I usually heated my water 10+ degrees over to adequately compensate for the heat absorbed and dissipated by the SS.
