Another question which, to a certain extent, should influence the arrangement of a house of any pretensions in respect to size, is that of the method of warming it. The preference, or rather prejudice, in favour of fireplaces is so great, that a revolution of the nation in political matters could be more easily brought about than the abolition of the fire-grate; but it is well known that at least three-fourths of the coal consumed is wasted in the attempt to heat the room to an equable and pleasant temperature. But by such means the result cannot be arrived at. In front of, and close to the fire, the temperature is excessive, while the backs of the sitters facing in are suffering from cold. An equalized temperature in rooms is obtained abroad. In Russia, a plan is adopted of heating the rooms by means of the walls, the latter being double, and so arranged that they act as flues to a furnace situated at the lower part of the building. By this method every part of the room acquires, simultaneously, an equable temperature. There need be no draught, simply because the air is not drawn in one direction more than in another. From every side a gentle current of warm air arises. This method cannot be adopted here; it would not suit for English houses where coal is used as fuel: the interstices of the double wall would soon be filled with soot. The same effect is produced in a far more elegant way, by means of warm-water pipes passed round the room; by this simple process the staircase and passages and the sides of a room distant from the fireplace are made of equal temperature—one, or at most two furnaces, burning coke and making no smoke, if placed in a cellar outside an extensive building, can render the whole interior, from attic to ground-floor of equal temperature, and not prevent the action of the fireplace, or its agreeable presence in our homes. In the British Museum, where warming apparatus is used, the temperature of the whole is kept uniformly the same, that is, 65° Fah., even throughout the most severe weather, independent of the common fireplace. No greater change is required in any part of our buildings than in the latter; not that it requires to be removed, but a change to prevent its waste of heat and its contaminating the outside air with the soot and blacks from its coal fuel; the lower fireplaces in a building should warm or air the upper rooms, and no soot or blacks should be allowed to leave the flues. A construction for this purpose will be shown in the ensuing pages, as well as one for warming an entire building and a conservatory.
