I have a one story house with a finished basement just North of Boston. I have an oil fired boiler and hot water baseboard heating in my home. The heating system has two zones, one for the basement and one for the upstairs. I currently don't heat my basement during the winter because I don't go down there very much and it stays about 59-60 degrees when it is cold out.

I am wondering if I could get better heating efficiency if I did turn on the heat down on the basement with the thinking being that there would be good transfer to the first floor as heat rises and it would be easier for the boiler and heating system to heat the basement. Is this right or wrong? I am naive about what would make the most sense in this case and would appreciate any advice people could offer.
