<p>The system has at least one burner, a heat exchanger, at least one pump and a feed and return, between which a pump and the heat exchanger are arranged and with which the system can be connected to a heating pipe network. It has a device between the feed and return that produces a signal dependent on the pressure difference between the feed and return that is used to control the revolution rate of a pump to regulate a constant pressure between feed and return for all mass flows. An independent claim is also included for a method of operating an inventive system.</p> |
