One Thousand Ways to Make Money by Page Fox

911. WASTE OF HEAT.--In our present systems of heating, from one-fourth

to one-third of the heat passes up the chimney and is lost. Could not some method be perfected by which this could be saved? It would be a great boon to the poor, who need to save every pound of coal, if this could be done. We suggest as one plan a stovepipe radiator--two pipes, open at top and bottom, traversing the vertical leg of the smoke-flue, by means of which the air of the room shall be taken in at one end and sent out at the other. There are at least 100,000 apartments heated by steam. A system which will add one-fourth to the heat of these rooms will be a material blessing. There should be millions in the invention.
