It's an older system as the house was built in 1924 when it was originally fueled by coal. Somewhere along the line there was a conversion to oil. We still have the original radiators. One of these days were going to have to pop your "house heated by oil" cherry. Except in custom situations I don't think too many homes are presently being built with radiators. It's mainly either forced air or electric baseboard. The house I lived in for few years as a teenager had forced air. I remember it being very dry. Update I really need to get a new program in place. I did a mismash of a sort of whole body workout and some ab work, which was fine for getting me to break a sweat and keep my interest level up, but it's not a long term solution. It's nice to feel warm in my house again.
