Abstract: A system and method for providing domestic hot water and/or space heating within a building. The system comprises at least one storage vessel comprising a removable cover, wherein an internal volume of the storage vessel is fluidly connected to a source of sewage and/or wastewater from one or more buildings, a water-source heat pump, at least one solar thermal collector, at least one heat transfer circuit. The at least one heat transfer circuit includes at least one fluid line containing a heat transfer fluid, and a controller for controlling an operation of the system. The system has an operation mode in which the controller of the system is configured to connect the at least one solar thermal collector to the at least one storage vessel via the at least one fluid line. The system stores a heat output from the at least one solar thermal collector in sewage and/or wastewater.

Abstract: An energy management system for a building. The Energy management system includes at a first thermal energy storage device for providing domestic hot water, a second thermal energy storage device for providing space heating, an electrical energy storage device, at least three state of charge analysers for determining the state of charge of said devices, a heat pump, a renewable energy generation device for providing electrical energy, and a controller configured to control an operation of said devices and to control an operation of the heat pump. The controller determines a state of charge of the at least one electrical energy storage device based on information of the at least one third state of charge analyser and to control a charging/discharging of the at least one electrical energy storage device based on a determined a state of charge.

Abstract: A thermal energy storage device comprises a tank and container. The container has an obverse wall, a reverse wall and an internal space. The internal space of the container contains a phase change material, and wherein the obverse wall and/or reverse wall of the container has a substantially planar surface, wherein the substantially planar surface extends from a cross-sectional centre of the container to internal wall of the internal space of the tank. The container is arranged in the internal space of the tank to define a flow path for a fluid in the internal space of the tank, the flow path allows a fluid to flow from opening of the tank partially over a surface of the obverse wall of the container and then partially over a surface of the reverse wall of the container.

Abstract: A system and method for heating and/or cooling at least one space uses a second heat transfer fluid which comprises or consists of water, at least one first encapsulated phase change material and at least one second encapsulated phase change material, wherein the first phase change material has a phase change temperature which is lower than the phase change temperature of the second phase change material. At least two indoor heat exchangers are employed, wherein each of the at least two indoor heat exchangers has a temperature sensor configured to determine a temperature information of the indoor space in which the indoor heat exchanger is located. A controller is employed which receives a temperature information from the temperature sensors and controls the system based on said temperature information. The system and method show an improved efficiency in heating and/or cooling at least one space compared to known systems and methods.
