best heat storage material
Best material to absorb heat and then slowly radiate that heat
In the first case you need a refractory, in the second case a melting paraffin brings excellent capacity (but may burn with a wick). The second factor of choice is material cost. Just a block of aluminium for instance is probably too expensive for a heater. This usually drives the choice to non-technical ceramics.

A new way to store thermal energy | MIT News | Massachusetts …
A common approach to thermal storage is to use what is known as a phase change material (PCM), where input heat melts the material and its phase change — from solid to liquid — stores energy. When the PCM is cooled back down below its melting point, it turns back into a solid, at which point the stored energy is released as heat.
Latent Heat Energy Storage | SpringerLink
Latent heat storage systems are often said to have higher storage densities than storage systems based on sensible heat storage. This is not generally true; for most PCMs, the phase change enthalpy Δh pc corresponds to the change in sensible heat with a temperature change between 100–200 K, so the storage density of sensible …
