Hi Diane,
I'm sure I get more sun in winter than you do but of course it gets much colder here.  To deal with that I have a large (300 gallons) tub of water as a heat sink; also, the greenhouse is attached to the south side of the house.  In any case, it only goes down to freezing but not below, except near the glass.  For you I would think a greater concern would too little light for growth, bad for geophytes but no problem for summer-growering winter-bloomers like camellia and cymbidium.  A fair number of the species I describe fall into this category.  
     I hope that helps, and I'll be interested in further thoughts.

How applicable would your information be to those of us who rarely see  
the sun in winter?

My unheated greenhouse manages to keep itself frost-free but if the  
sun does come out, the temperature may go up only a degree or two.
