A passive sequential pump system for use in moving a fluid is provided. The system comprises a plurality of valves. Each valve of the plurality of valves is positioned adjacent to another valve of the plurality of valves. Each of the plurality of valves includes an opening and an inner surface. The inner surface is expandable towards the opening. The system also comprises a conduit defined by the opening of each of the plurality of valves. The system further comprises an air source providing air to each of the plurality of valves and a controller controlling the air source to each of the plurality of valves. The system generates peristaltic motion to move a fluid through the conduit by increasing the air in each of the plurality of valves, thereby correspondingly closing each opening in sequence, peristaltic motion is generated to move a fluid through the conduit.

At least one thermal input heat exchanger (55) is located in the thermal store (52), the at least one thermal input heat exchanger having a first side adapted to receive heat from the outer thermal storage mass (49), and a second side in contact with the thermal store medium. At least one thermal output heat exchanger (53) is also located in the thermal store (52), the at least one thermal output heat exchanger having a first side in fluid communication with a hot water and/or heating supply, and a second side in contact with the thermal store medium.

A hydraulic valve assembly having a regeneration circuit, where the hydraulic valve assembly is switchable between a regenerative mode and a non-regenerative mode as the valve assembly supplies fluid to operate a hydraulic device. The hydraulic valve assembly may be automatically switchable between the regenerative mode and the non-regenerative mode, such as by utilizing a pressure control valve in the hydraulic circuit that is activatable at a predetermined pressure setpoint, or by utilizing a variable pressure reducing valve that actuates a spool in the hydraulic circuit. In other embodiments, the hydraulic valve assembly may be manually switchable between the regenerative mode and non-regenerative mode by utilizing a valve member operatively coupled to a solenoid in cooperation with one or more check valves in the regeneration circuit.
