A heating system incorporates one or more reactors (10, 30, 40, 50, 66, 68) containing a complex compound of a metal salt and a polar gas adsorbed thereon in which the volumetric expansion of the complex compound is restricted during adsorption and which reactors (10, 30, 40, 50, 66, 68) comprise one or more reaction chambers having a maximum mean mass diffusion path length of less than 15 mm, and/or a maximum thermal diffusion path length of less than 1.5 mm, means (18, 72) for heating the complex compound in the reactors (10, 30, 40, 50, 66, 68), a condenser (12, 32), an evaporator (14, 34) and conduit means (11, 17, 21, 22, 23, 24, 26, 31, 33, 39, 47, 52, 53, 54, 60, 81) for directing polar gas from the reactors (10, 30, 40, 50, 66, 68) to the condenser (12, 32), from the condenser (12, 32) to the evaporator (14, 34) respectively through the reactors (10, 30, 40, 50, 66, 68) for cooling them and from the evaporator (14, 34) to the reactors (10, 30, 40, 50, 66, 68). |
