摘要： A heating system (100), a controller (110) for a heating system and a method of controlling a heating system (100) suitable for responding to grid stress events are disclosed. A heating system (100) comprises a tank (104) for holding water; a heat pump (102) arranged to provide heat to the tank (104); an electric heating element (108) disposed in the tank for heating water; and, a controller (110) configured to: control electric power from an electric power grid to the heat pump (102) and the electric heating element (108); detect a grid stress event; determine a heat pump energy penalty for providing heat in response to the grid stress event under a present operating condition; and, vary, in dependence on the determined heat pump energy penalty, a power provided to the electric heating element (108).

摘要： A water heating system is described. The water heating system comprises a vessel for holding water and for receiving heat from one or more heat sources for heating water in the vessel. The water heating system comprises a sensor comprising a plurality of temperature sensing elements for sensing a distribution of temperatures in the vessel. The water heating system comprises a connector for connecting the sensor to a retrofittable tank controller. The water heating system is configured to provide one or more characteristics of the water heating system to a retrofittable tank controller such that a retrofittable tank controller connected to the sensor and in receipt of the characteristics of the water heating system can determine from the distribution of temperatures in the vessel a quantity of useable heat stored in the vessel. A retrofittable tank controller for controlling a water heating system is also described. A sensor for measuring a temperature distribution of fluid within a vessel is also described.

摘要： The present invention relates to a hot water storage tank (202, 302, 402, 502, 602, 702), defining a primly storage volume (204, 304, 404, 504, 604, 704), with at least one heat source (212, 312, 412, 512, 612, 712) positioned in and operable to directly heat water in the upper portion (207, 307, 407, 507, 607, 707) of the primary storage volume (204, 304, 404, 04, 604, 704), and a pump or other means (237, 337, 437, 537, 637) that draws water, from the lower portion (209, 309, 409, 509, 609, 709) of the tank into a heat transfer device (216, 316, 416, 516, 616, 716), situated in said upper portion (207, 307, 407, 507, 607, 707). The heat transfer device (216, 316, 416, 516, 616, 716) is configured to enable the transfer of heat from heated water in the upper portion (207, 307, 407, 507, 607, 707) to the drawn water prior to discharge into the water in the upper portion (207, 307, 407, 507, 607, 707).

摘要： A controller interface (B12) between a hot water tank controller (B13) and a heat pump controller (B2) in a heating system is provided. The controller interface (B12) comprises a response module configured to receive, from the hot water tank controller (B13), a first signal indicative of a temperature. The response module provides a response signal based on the first signal and a temperature response characteristic and communicates the response signal to the heat pump controller (B2). The controller interface (B12) enables interoperability of a heat pump controller (B2) and a legacy hot water tank system and hot water tank controller (B13).
