A heating installation for premises includes a controller coupled to an air source heat pump; a premises heating arrangement; and a local weather sensing arrangement. The controller is configured to receive weather forecast data from an external source, and local weather status information from the local weather sensing arrangement. The controller is also configured to set a control algorithm based on both the weather forecast data and the local weather status information, and control a supply of energy from the air source heat pump to the heating arrangement based on the set control algorithm; and increasing energy input into the heating arrangement in anticipation of a forecast fall in the temperature of the air from which the air source heat pump extracts energy. A method of controlling a premises heating installation is also disclosed.

A method for controlling a distribution temperature of domestic hot water implemented in a management unit of an installation for producing domestic hot water and including steps for obtaining mean temperatures of the distributed hot water, determined by time ranges and measured by one or more divisional distribution meters in the course of a reference period; obtaining a minimum value and a maximum value of these temperature averages in order to determine a temperature condition of the distributed hot water from at least the maximum value or the minimum value, and from at least one predefined temperature threshold, and, if the distribution condition determined is met, sending a sequence controlling the production temperature to the production installation. Also, a distribution installation, a distribution meter and a unit for managing the distribution of domestic hot water.
