Most homes in San Francisco have zero heat. Many added a gas wall heater in the late ‘50’s but they are a ridulcus heating method. To stay warm in Frisco, drink hot toddy’s, where three layers; t shirt, flannel shirt, hoody, rest in bed with you running laptop on you chest, and — go to the corner bar full of people and drink some more.

I was horrified the first time I saw a gas wall heater. Gas fireplace to heat the outside! Even more horrified when my Lebanese roommate needed to keep the ambient temperature 85 using a gas wall heater.
