Good thread going here, was thinking of adding that to my house as well.

But, you can add all the roof heaters you want, if the gutters freeze up solid with ice, and you still have heat loss in the house, you are still going to have icicles, and the wieght of them might pull down your gutters. I reinsulated the attic and vented it and that eliminated the Daming of the ice on the roof, but my gutters froze over from the sun melting the snow.

Any ideas on gutter heaters, some I've seen look very pricey, and I saw where there cost @.35/hr to operate.
Any clues?
