UltraSun UFD Flatplate



Ultrasun UFD Flatplate solar hot water systems are established and effective heaters that provide excellent performance, good value and guaranteed long life. They are of Open Loop thermosyphon type with the water flow circulating through the collectors and being stored in the tank ready for use. Features include:-

  • A heavy-duty tank that features a resin insulated totally weatherproof GRP casing, a heavy-duty galvanized cylinder internally piped to optimize hot water availability and magnesium sacrificial anode for cathodic corrosion protection.
  • Solar collectors that incorporate full area copper absorption plates ultrasonically welded to copper circulation tubes, high specification insulation and tempered security glass to provide energy absorption of up to 95%.
  • Low thermal conductivity high specification plastic collector tank connection piping with silver foil coated polystyrene insulation jackets.
  • Connection piping that includes an incoming non-return valve, a thermosyphon diverter valve controlling max water temperature to 60º C to avoid scalding on hot days, pressure release valve, and drain cock. All fittings are provided from the inlet to the outlet for simple installation.
  • Galvanized mounting frame.

Ultrasun UFD Flatplate solar water systems are available in various tank sizes and collector configurations to suit domestic and small-scale institutional applications. They are effective and robust products designed for many years of trouble-free operation with a 5-year guarantee to demonstrate the product quality. With the benefits of progressive design and high-quality components, they are the ideal solution for all solar water heating applications.
