Zusammenfassung:PROBLEM TO BE SOLVED: To provide a solar heat collecting apparatus capable of surely determining the completion of filling with a heat medium in a heat collecting circuit and combining improvement of heat efficiency and shortening of a trial run time.SOLUTION: This sealed circulating type solar heat collecting apparatus 1 includes: a heat collecting panel 2; a hot water storage apparatus 3; the heat collecting circuit 4 formed with a heat exchanger 10; and a gas-liquid separating means 5 provided downstream of the heat exchanger 10. The solar heat collecting apparatus 1 further includes a passage means 6 connected to an upstream portion of the gas-liquid separating means 5 and having a visible part that makes visible the flow of antifreeze liquid. The antifreeze liquid returned via the heat collecting panel 2 or the like can thereby be visually confirmed.
