<p>A method for efficient control of a solar heating system has two sets of temperature sensors; one (4) on the solar modules outlet and one (6) on the heat storage/user point. The control system (1) monitors the temperature difference as well as the output from a solar sensor. The frequency and level of operation of the circulating pump (3) is controlled via the temperature difference, which ensures the pump only operates when there is sufficient solar heating.</p> |
