Abstract
The invention relates to a heating system of the type in which a radiator in a room has the flow of a heated fluid thereto from a central source such as a boiler controlled by a thermostatic valve. The valve normally has a sensor associated therewith to which the valve reacts which senses room temperature. An electrical heating resistor is positioned in close proximity to the sensor. A solar cell positioned as in a window so as to be impinged upon by rays of the sun is electrically connected to the heating resistor and the resulting current developed by the solar cell is utilized to effect a heating of the resistor which is related to the intensity and angle of the sun's rays. The heat generated by the resistor supplements the sensed room temperature so that the valve is operated in a way which takes into account the radiant energy to which a room is subjected by the sun.
