I'm buying a 100+ year old house which currently has no heating. The owners have been living there almost 20 years and say they've never needed it. There are gas pipes in the rooms for radiators, and I'm wondering about the cost and efficiency of putting in radiators vs. central heat. I'd probably only use either a few months out of the year.

I live in Austin, TX, so I plan to install central air, and it was pointed out to me that as long as I'm doing that it would be natural to put in central heating as well. However, I've always loved radiator heat and the connections are already there, so I was hoping someone would be able to help me with the comparison?
