The factory always suggested keeping the sticky stuff dispenser in an appropriately sized cabinet along with a light bulb for heat.   40 to 60 watts are what I have heard to work just fine for most folks.  Just leave the light on and your resin and hardener will always be at a nice working temp.  The biggest problem you have with cool temps is that the viscosity goes up making it more difficult to get thorough and timely wet-out of your layups.  A cold substrate will also make the surface harder to wet to insure complete adhesion.  There are many solutions, localized heating being the most common. Some infra-red lamps will warm the surfaces and a heat gun can be used to raise the temp of the resin either prior to or during application.  Depending on how your do your layups, customizing a controllable heat source is pretty simple, just use your imagination.  Localized heating is much less expensive than cranking up the thermostat as well, that's for sure.
