A hydronic radiant heater bed warmer (RBW) is mounted in the support structure beneath the top surface of a conventional bed that has a mattress on springs supported by the bed support structure. The RBW includes: a source of heated supply water; a supply water line from the source; a return water line to the source; one or more heating loops each including [a length] lengths of tubing through which water flows from the supply line to the return line; a water pump in one of the water lines for pumping water over the closed path from the source, to the supply water line, to the heating loops, to the return water line and back to the source; thermally conductive plates mounted in the bed support structure under the top surface thereof; and accommodations for holding the lengths of tubing in intimate thermal contact with the plates including: spaced apart co-planar plate holding boards of the same uniform thickness, each having length and width and together providing a surface area for holding the plates and elongated spaces of uniform width therebetween for holding the lengths of tubing, the plates are held flat against the holding boards holding surface area, the elongated spaces have depth and length as well as uniform width of which the depth is equal to the boards thickness and the length is equal to the boards length and the lengths of tubing are held in the elongated spaces intimate thermal contact with the plates; so that the plates are heated by conduction of heat from the lengths of tubing; and the plates radiate heat to the user on the bed top surface.
