My great-grandmother lived in a house,built in the early 1900s,in the middle of the city,that was wired for electricity,but not piped for gas. She had asthma and couldn't stand the smell of burning gas. She cooked and heated with COAL.That didn't bother her and actually was very theraputic. By the time I came into the world, the house,unfortunately had been piped for gas and there was a gas space heater in one of the front rooms and the coal range had been replaced with a gas one.My dad said she knew when someone lit the heater even though she was in the back of the house.They never used it for that reason. She died in 1967,and I still remember her tan base burner coal stove in front of one of the fireplaces.
I think I have inherited some of that tendency. I can't stand the smell of an old-style unvented gas heater. I thought it was my imagination,but then I found out there was some truth to it with all the articles about how bad they are.The new ODS heaters don't seem to bother me as much-I think they may be cleaner burning.
