Abstract: There are herein described energy storage systems. More particularly there are provided thermal energy storage systems comprising battery assemblies containing phase change materials and a monitoring system therefor. In addition there are provided thermal stores comprising battery assemblies having integral control means for management of the thermal energy provided by the battery assembly.

Abstract: There is herein described a heat battery design for horizontal and vertical planes and a heat battery using a separate volume compensator. In particular, there is described an improved heat battery design which overcomes the problem of over-pressurisation within a battery cell during use.

Abstract: The present invention relates to phase-change materials (PCM) which store and release thermal energy by undergoing melt/crystallisation cycles. More particularly, there is described a thermal storage system where sub-cooled phase change material (PCM) is nucleated via a controlled thermal region(s).

Abstract: The present invention provides an energy storage system (10) for a use with a boiler (20). The energy storage system (10) comprises a plurality of thermal energy storage banks (101, 102, 103, 104). Each thermal energy storage bank (101, 102, 103, 104) comprises phase changeable material having a predetermined phase transformation temperature. The energy storage system (10) also includes an extraction device (105; 1 15) configured to recover waste energy from the boiler (20). The extraction device (105, 1 15) is operable to extract waste energy from the boiler (20) and feed that energy to at least one (101) of the thermal energy storage banks (101, 102, 103, 104). A controller (106) is arranged, in use, to activate the extraction device (105, 115) in response to operation of the boiler (20).

Abstract: A water heating system for a number of apartments or offices 10 each having a water store 15 for receiving hot water from a common boiler 12. The system includes a temperature sensor S2 for sensing the temperature of incoming water from the boiler, with a valve V1 between the temperature sensor S2 and the water store 15. A further temperature sensor S1 senses the temperature of water within the store 15. An electronic controller 30 controls the flow of water via valves V1, V2 dependent on the temperature detected by both the first and second sensors to prevent water being received by the store when the temperature differential is too small. This avoids the risk of reduction of the water temperature within the store 15, and meter 21 will not register utilization under these circumstances as valve V2 allows the return of the water other than via store 15.
