Description: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A furnace having in combination a casing and a radiator, said radiator being mounted within said casing in spaced relation thereto thereby forming an air-conducting passage between said casing and said radiator, said radiator
comprising a combustion chamber and a plurality of tubular air-conducting elements mounted within said combustion chamber, each of said tubular air-conducting elements being spaced from the others thereby defining intercommunicating passages for conducting combustion-gases, certain of said gas-conducting passages being in direct communication with said combustion chamber, said air-conducting passage in combination with said air-conducting elements forming a multidirectional air-heating passage through said furnace; certain of said plurality of air-conducting elements being situated concentrically with respect to said air-conducting-passage and at least one of said plurality of air-conducting elements.

2. A furnace according to Claim 1, one of said plurality of air-conducting elements being mounted centrally of said radiator, the remainder of said elements being mounted concentrically about said central element and between said central element and the passage formed between said casing and said radiator.

3. A furnace according to Claim 1, said radiator having mounted therein a pair of spaced-apart plate-like elements, said air-conducting elements being mounted between and secured in gas-tight relationship to said plate-like elements.

4. A furnace according to Claim 3, the lowermost of said plate-like elements having an air-deflecting element formed integral therewith.

5. A furnace according to Claim 3, the lowermost of said plate-like elements having a downwardly and inwardly extending air-deflecting element formed integral therewith.

6. A furnace as claimed in Claim 1, said radiator having an exhaust pipe secured in gas-tight relationship thereto, and a supplementary gas-chamber secured thereto at the point of exit of the exhaust gases into the exhaust at the stack pipe, said chamber serving to raise the exhaust temperature at the stack.
