It is certainly not ideal. I will have to look into one of those sensors. Due to where I am living now it is my only option. However, I have not had a problem with it until now. It was my own fault it went off. It has a safety feature that turns it off automatically if something comes too close to where it is emitting the heat, and I left my watering bucket too close. I do worry sometimes about it going out. I check it several times a day. The only risk is the time when I'm sleeping between 9-10 pm and 5 am. Always check temps last thing in the evening and first thing in the morning. It has a thermostat that turns it on and off according to the temperature I have it set at, and it has been very accurate to this point. I plan to have things set up much better in a couple months when I move. Thank you for the input.
