Mechanical Heat from Ching Visual Dictionary of Architecture

Mechanical System = Any of the systems that provide essential services to a building, as water supply, sewage disposal, electric power, heating, ventilation, air-conditioning, vertical transportation or fire fighting

Space heating = the heating of a limited area, as a room, esp. by means of a heat source located within the space.

Franklin stove = A cast-iron stove resembling an open fireplace but having enclosed sides, back, top and bottom, with a front completely open or able to be closed with doors.

Stovepipe = a pipe, usually of sheet metal, serving as a stove chimney or connecting a stove with a chimney flue.

Thimble = A protective sleeve of sheet metal passing through the wall of a chimney, for holding the end of a stovepipe.

Central heating = A mechanical system that supplies heat to an entire building from a single source through a network of ducts or pipes.

Thermostat = device that automatically responds to changes in temp. and activates switches controlling such equipment as furnaces, refrigerators, and air conditioners.

thermocouple = device for measuring temp. in which a pair of dissimilar metals, as copper and iron are joined so that a potential difference generated between the points of contact is a measure of the temp. difference between the points.

bimatellic element = a material made by bonding two metallic strips having different coefficients of expansion, used in temperature indicating and temp. controlling devices.

Combustion air = Air required for combustion of fuel in a furnace

Furnace = apparatus in which heat is produced, as for heating a house or producing steam.

horizontal furnace = a furnace designed for installation in a low attic or crawl space.

wall furnace, recessed in or amounted on a wall and supplying heated air directly to a space without the use of ducts.

Heating load = The hourly rate of net heat loss in an enclosed space, expressed in Btu per hour and used as the basis for selecting a heating unit or system.

Heating degree day = A degree day below the standard temp. of 65 deg F, used in estimating fuel or power consumption by a heating system.

Degree day = A unit that represents on degree of departure in the mean daily outdoor temp. from a give standard temp..
