A local heating system is presented. The local heating system can be connected to a heating grid (110) and can be connected to a first heat source (10) arranged to extract heat from the heating grid (110) and an electrical energy grid (120). There is a second heat source (20) that converts the electricity supply through the electric energy grid (120) into heat, a heat radiating device (30), a heat radiating device (30), a first heat source (10), and a second. A distribution system (40) for circulating the heat transfer fluid to and from the heat source (20), and a heating grid (110) and an electrical energy grid (120) by the first heat source (10) and the second heat source (20). ), A controller (50) configured to control the relative withdrawal of heat from each.
