I think the problem is that homes are also designed to cool, efficiently, which is why many a/c and heater units are in the attic with vents in the ceiling.

This means that they tend to heat homes more inefficiently than in places that are used to very cold weather.



Attic equipment is mainly for low install costs. Easy to run the ducts. It's terribly inefficient.


If that's true people should insulate their attics. Or just keep the taps running and jump into insulated sleep bags at night.
