Maintain the heater settings. Shutting the heater down will result in colder water temps that the heater has to overcome when it is turned on again and will cost you in the amount of BTU Therms you use. -- more expensive. I believe that it takes approx. one hr. to bring the temp up one degree.

take it out of the oven and leave on a raised surface. leave for as long as it takes to cool down. Ten to 15 minutes should be plenty.
The heater core could be burnt out. Make sure your antifreeze is full and your switches on the dash are working. When you move the switch from cool to warm you should be able to hear a difference. If you don't the door/flap may not be moving.
