Development of transportable thermal-storage space heaters

Reference is made to the shortage of generation, transmission and distribution capacity following the end of the 1939¿45 War and upon the resumption nationally of normal activities. This prompted a renewal of interest in the storage of energy in the form of heat, and the paper describes briefly experiments that were made leading to the design and production in this country on a commercial basis of transportable unit-type thermal-storage space heaters. The suitability of buildings for this form of heating is discussed, as also are methods of planning and controlling installations. In forecasting the future of this form of heating there is reference to electricity tariffs and to the relative costs of electricity and other forms of fuel.
