I'm thinking of using the LM56:

My question is what is typically used as the heating element. I'm
planning on using it to switch in a heater when the temp drops below a
certain threshold and to switch it out when it hits another threshold.
The temp here in the winter time can hit below -20C not including the
wind chill. Is it possible (practical) to keep an enclosure a weather
tight (PVC) (1.25" x 4") at a minimum of say 10C under such
conditions? Or should I be looking at another device or method.
What I'm thinking of doing is like fig 7 of the application note on
the LM56.
