The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commerciall

The reactants H 2 and O 2 contain more bond energy than H 2 O, so when they combine, the excess energy is liberated given off in the form of thermal energy, or "heat". By convention, the energy content of the chemical elements in their natural state (H 2 and O 2 in this example) are defined as "zero". This makes calculations much easier, and

Best material to absorb heat and then slowly radiate that heat

You have to decide whether heat is to be radiated by the material or brought to the users by blown air. 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.
