Performance of a heating system depends on the interrelationship of its component parts. One measure of performance is the cyclic room air temperature swings. This paper presents results of analog computer tests of the predominant factors influencing such air temperature swings: design capacity of the heating system, time constant of the heater, the space itself and furnishings, and the thermostat cycling rate. Also considered is the influence of the heating system on the control air temperature droop.
