A phase transition can store lots of energy without the inconvenience of changing temperature.
Melting water ice into liquid water at 0°C takes approximately as much energy as heating the same amount of water from 0°C (assuming that it is already/still liquid) to 80°C.
With a material that has a transition temperature of e.g. 21°C, a room could be kept at a very pleasant temperature even when energy is flowing into or out of it.
