[QUOTE="guest poster, post: 542782, member: 262401"] I actually did look for ice dams... it's nothing to do with it.. the freezing is general cold/ freezing weather, snow fall and rain or a temperature differential that melts then freezes the rain or melt water into an ice dam. That is not the same as an isolated cooling element at minus 30c from a butchered freezer or peltier that air born moisture condensates and freezes on -30c (and you want it to be -30c). If you leave a freezer door open it will just carry on freezing until it goes beyond the door, as I said- even if the central heating is on. If you fire up a peltier on its own but with an appropriate cooler on the hot side- ice will form on the cold side. You routinely see gas bottles with ice build up in the middle of summer. This is very basic and not really worthy of too much other than if it causes too much of a problem then it needs dealing with. It's getting it to work and at low cost/ running cost that should be the focus. Also, if you vent it, you lose a lot of the efficiency - you need to do the opposite and lag it keeping the cold in. :cool: [/QUOTE]
