The heater is in the form of a hot water carrying pipe coil supported on a suitable base, such as a sub-floor, and having spaced parallel pipe ducts interconnected by pipe bends. A pair of parallel supporting laths, preferably in the form of flat bars, are fixed on the sub-floor in spaced relation to the opposite side walls of a room to be heated, and circularly curved members are secured to the laths at spacings therealong equal to the spacing between the pipe ducts, the curved members on one lath being staggered longitudinally relative to the curved members on the other lath. The connecting bends of the pipe coil are looped around these curved members, which latter thus serve as a pipe laying gauge. Stop members are secured to the laths in spaced relation to the free ends of the curved members to form, in effect, troughs for the connecting pipe bends. Heat transmitting metal lamellae are secured to the pipe ducts to interconnect adjacent pipe ducts, and these lamellae may be formed with half-shell portions at each end, one overlying a pipe duct and the other underlying the adjacent pipe duct. The lamellae may be formed with alternating rows of depressions and elevations. In hard to heat areas of the floor, the parallel pipe ducts may be arranged much closer together than in the remainder of the floor, as by having a pitch which is one half the pitch of the pipe ducts in the remainder of the floor and, in such case, the curved members in the hard to heat area of the floor have an angular extent of more than 180 DEG and a radius which is less from that of the curved members in the remainder of the floor. The lamellae may be metal or may be metal powder-containing plastic. |
