If you have "forced hot water", it can be used in the floors and in ring the outside walls. It is also designed to be zoned so that each room can be individually controlled.
Slant/Fin Fine/Line 30 8 ft. Fully Assembled Enclosure and Element Hydronic Baseboard-101-401-8 - The Home Depot
Water flows through the base board and I expect you can force it through the floors.
