The heat has to come from somewhere. I see about 8 degrees different in the water temperature when running the Heater. One of the reasons to run a grill block, beside aero, is to help warm up quicker and run hotter. The hotter the engine, to a point, the better the FE.

The Old beaters I drive when it starts to overheat I can turn the Heater on Full blast and the temp will drop.
