Patent ID: 8855475

Claim:
A radiant heating system constructed and arranged for interconnection to a power source for heating a desired area and having a closed fluid flow circuit comprising: a housing comprising: (a) a top plate for covering and sealing an upper surface of the housing, the top plate having a plurality of openings defined therein and having an inlet for permitting a flow of coolant to enter into the housing and an outlet for permitting a transfer of heated coolant out of the housing, wherein a diameter of the inlet is greater than a diameter of the outlet, the inlet and the outlet being constructed and arranged for connection with an inlet pipe and an outlet pipe, respectively; and (b) at least two baffle plates internally positioned within the housing, the at least two baffle plates having different lengths from one another within the housing; a plurality of heating elements constructed and arranged for insertion into the plurality of openings and projecting into the housing whereby the plurality of heating elements are in direct contact with the coolant, the plurality of heating elements being accessible from an exterior surface of the housing to permit removal of the plurality of heating elements from the housing without disassembly of the housing and without disconnection of the housing from the closed fluid flow circuit; a pump in communication with the heating system for continuously circulating the coolant throughout the closed fluid flow circuit, wherein the inlet pipe and the outlet pipe are interconnected to form the closed fluid flow circuit, the interconnected inlet pipe and outlet pipe being constructed and arranged to radiate heat to the desired area by means of the heated coolant flowing therethrough.
