1. A building heating system, comprising:
at least one air source heat pump configured to transfer heat from air to a working fluid conducted through a working fluid line,
said working fluid line comprises at least two electrical heating tubes configured to heat said working fluid during flow-through of said working fluid, wherein each of said heating tubes is, directly or indirectly, connected or connectable to said heat pump, and wherein said working fluid line is connected or connectable to at least one water heat exchanger for transferring heat from said working fluid to water conducted through at least one water line of a building water system,
at least one temperature sensor configured to measure the temperature of the working fluid and/or water conducted through at least one water line, and
at least one control unit connected or connectable to said at least one temperature sensor, wherein said control unit is configured to individually control the electrical heating tubes based upon the temperature detected by said at least one temperature sensor.
