There are themostatic switches that will turn something on a variuos temps available. I have on in the well house that controls an IR bulb to keep it from freezing. You can get them at the home repair/building stores or Amazon, etc. http://www.amazon.com/Farm-Innovators-AFITC3-Thermocube-Controller/dp/B0006U2HD2/ref=sr_1_2?ie=UTF8&qid=1357157191&sr=8-2&keywords=thermostat+switch
About leaving it on for extended periods - a warm engine will experience less condensation and therefore rust on the internal parts (cam in particular), so might, *in theory*, extend the life of the engine. This is a big deal in aircraft engines that are used perhaps once a week - not so much in daily drivers, but might be something to take into consideration to balance the risk of burn-out of the heating element and cost of electricity. No, I have not done this with mine, YMMV.
