Re: [GBlist] question about turning heat down

[Anja Kollmuss <anja.kollmuss@tufts.edu>]

Hi Jan,
Thank you for your note. That's what I had thought. But I run into the
argument (that turning off your heat over night can waste more energy
than just lowering it) so often that I started to think maybe there is
something to it I don't know.

Thanks again!
