Warmth, a term expressing a moderate degree of heat.

The warming of houses, in a climate so variable as that of Britain, is an object of the first importance, both to health and domestic comfort : hence, the invention or discovery of the most economical method of effecting such purpose, has engaged the talents of many able philosphers and artisans. Having already stated several of their useful contrivances, in the articles Fire-place, and Stove, we shall now lay before our readers the following Cut, which represents a simple, and perhaps the least expensive, mode of communicating warmth from the kitchen-fire, throughout houses, manufactories, or other buildings, by means of steam.

warming of houses

A, is a copper furnished with a still-head, and fixed over the fire.

B, a leaden or copper tube, proceeding from the vessel, and being heated by the steam of the boiling water: it is carried through eight rooms (as delineated in the figure above given) ; traverses that side of the wall where the chimney is usually erected ; and is likewise provided with stop-cocks, C, C ; by means of which the course of the steam may be accelerated, or retarded, at pleasure.

D, is the spot, at which the steam is discharged, after having circulated through the rooms.

E, is a cistern, by which the copper may be occasionally supplied with water.

This contrivance was proposed many years since, by Col. William Cook: it deserves to be more generally known, on account of its obvious simplicity : uniting convenience with economy, in warming a number of rooms by one grate : a considerable saving in fuel will thence result, while the kitchen-fire may, at the same time, employed in roasting, or in any other culinary process. - See the article Room.
