A lot of people use Flexwatt heat tape. This is, in my opinion, the best route, yet it is the most expensive route. For you, you may do well on say, one foot of 11" flexwatt heat tape. Heat tape gets extremely hot, so you must use a thermostat to regulate the heat so it doesn't get too hot. There's Johnson, Ranco, Helix, and Herpstat.
flexwatt most expensive? how so? because you have to buy a thermostat for it?
