One small way in which engine heat can be harvested for gain is to park the car inside the garage in winter, and outside in the summer. That is, so long the garage connects directly to the house the heat from the engine can and does warm the air inside this garage to a point and it does make a small difference in the home's cooling and heating efficiency.
