Solar energy products Galvanized Steel Non pressurized Thermosiphon Solar Water Heater 320L 30 tubes

Solar- Constant Pressure. - No mixing to avoid water contamination - Higher efficiency heat transfer - CE and ISO9001-2008

SD-ECO S2 Models

Solar Design SD-ECO S2 models exist in four different sizes (please download the technical datasheet for more info).

For a better adaptability, four angles of frames are available (8°, 20°, 38°, and 45°) and can be installed on metal or tile roofs.

SD-ECO S2 models are equipped with 1500mm length vacuum tubes and 58mm diameter. This ideal size optimizes the ratio size/yield/strength of solar water heaters.
