That has a setting where on earth you can give it the amount of hours or exact time, and it will turn rotten at that time? I have one that have something like this, but instead of running straight through the number of hours I've given it and afterwards stopping, it goes bad and on and off and on previously it finally stops after the hours are up. I need something that will run right through till the hours are up.

Answers:    I haven't see an electric heater beside a timed setting, only a thermostat. You can buy a separate 120 volt plug surrounded by timer ( @ Home Depot, Lowe's, etc.)and run your heater through this and it would hold power for the amount of time allotted. The issue is the heater turning on and sour, I have not see a newer model electric heater lacking a thermostat, but if the area you be trying to heat never reach the set point of the thermostat, it would do what you are asking. The only other style is to bypass the thermostat, which is not very safe and sound.
