I am looking into rehabing a 1910 Farmhouse in Western Mass. I love so much about it and want to leave as much original as I can. However, there is no heating system. I am wondering what would be the easiest and most efficient type of heating system to install so as not to have to do much demo to the property. Would you recommend an oil or electric heating system, baseboards or air ducts? Any direction would be greatly appreciated!
