Let me start by saying I do not live in North anything. I live in houston tx, a cold day is 40 degrees, but when my husband gets "cold" he turns the heat to 80 or more. My electric bill would be ungodly. Other than that I am roasting. How do I get a more realistic temp. And please don't say 'turn it down' I do and then you have to listen to HOW COLD IT IS and he turns it up past 90. he is a reptile, no body heat, and i am now cooked .... any sugestions?
