  The multicaloric effect is defined as the adiabatic temperature change in
multiferroic materials induced by the application of an external electric or
magnetic field, and it was first proposed in 2012. The multicaloric effects in
multiferroics, as well as other similar caloric effects in single-ferroics,
have been the focus of much research due to their potential commercialization
in solid-state refrigeration. In this short communication ar-ticle we examine
the thermodynamics of the multicaloric effect for solid-state heating
applications. A possible thermodynamic multicaloric heating cycle is proposed,
and then implemented to estimate the solid-state heating effect for a known
electrocaloric system. This work offers a path to the implementation of caloric
and multicaloric effects to effi-cient heating systems and we offer a
theoretical estimate of the upper limit of the tem-perature change achievable
in a multicaloric cooling or heating effect.
