Feolite, one of many materials used for heat storage, being a solid, does not have any volumetric or pressure containment issues, but correspondingly does require the use of a transfer medium to then get the stored heat to the desired location.[3]
Heating systems with a storage component now widely use feolite as the storage core.[8]
Application
Blocks of feolite enclosing sheathed electric heating elements to form a heat storage core, surrounded by thermal insulation, are used in storage heaters and storage radiators.[9][10] Because feolite blocks will conduct electricity, electric heating elements must be electrically insulated when used with feolite storage.[11]
The typical heat exchange medium for feolite storage is air.[10][12][13]
Feolite has been considered for use as a component for braking systems in railway rolling stock.[14]
