A method of operating an apparatus for providing heat and power to an installation; the apparatus being operable in at least two heat production regimes, such as a heat pump and a boiler, and including a connection to an external electricity network, wherein at least one heat production regime results in the production or consumption of electricity; the method comprising: determining a profile of heat cost against electrical power demand from the installation for heat produced by each heat production regimes taking into account a value of the electrical power produced or consumed, selecting the heat production regime that has the lowest heat cost for the current electrical power demand, and using this heat production regime to provide heat to the installation. |
