Any system of piping suitable for hot-water heating can be employed for this purpose: the one shown is that of the complete-circuit or one-pipe system, the heated water being taken directly to the top of the building and all radiating surface supplied by the descending current. As the writer knows from experience, it is very difficult indeed to proportion the heating surface in the furnace and the radiating surface in the room so as to give in all cases satisfactory results without an An admirable series of articles were written on this subject by J. W. Hughes, and appeared in Metal Worker, February, 1895. irregular and uncertain distribution of heat. It will generally be found that the fire maintained in a hot-air furnace is mrch more intense than that in a steam or hot-water heater; and further, the heating surface which is usually employed is subjected to the full heat of the fire, consequently a smaller amount of heating in proportion to radiating surface must be Fig. 179.--Combination System.

Whereas in the ordinary hot-water heater one foot of heating surface supplies from 8 to 10 of radiating surface, in this system 1 foot of heating surface will supply 25 to 35 feet cjf radiating surface in coal-burning furnaces and 50 to 75 in wood-burning furnaces. Similar combination systems of hot air and steam are also used, but in such cases the heater must be very much like a steam-boiler, and possess all its appliances and also storage capacity for steam.
