- Although Stavros debunked this elsewhere in this thread, I'll
- do it here. The laws of thermodynamics says that the heat loss
- is directly proportional to the temperature delta. It is never
- more expensive to let the house cool down and reheat. It is not
- like a car, the furnace operates at essentially a constant efficiency.
- In fact, the furnace is probably a bit more efficient in the longer
- runs for reheat, but doesn't make a big difference.
