There are ceramic heat bulbs that you can get. You use them the same way you would heat lamps, but they don't give off light. I have a 250 watt and a 150 watt in my main coup which is well insulated. They are plugged in to a thermostat regulated outlet, so they turn on at 32 degrees, and off at 45.
