ABSTRACT:
An electric heating device warms by radiation and convection. A metal casing holds a quantity of heat-conducting oil, with a remaining relatively small volume of space in the container evacuated of air and occupied by an inert gas under subatmospheric pressure. An electric resistance element in the lower part of the casing heats the oil and is positioned so that the oil circulates by thermal convection. An insulative jacket may be placed around the heater making the device capable of storing and giving off heat for relatively long periods of time.
