1. SPECIFICATIONS

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:-

 

•  Heavy duty tank that features a resin insulated totally weather proof GRP casing, a 

heavy duty galvanised cylinder internally piped to optimise hot water availability and 
magnesium sacrificial anode  for cathodic  corrosion  protection.  An  in-built 3kW 
electric water heater with thermostat is included as standard. 

 

•  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 

0

diverter valve controlling max water temperature to 60 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.

  •  Galvanised 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.

DESIGN FEATURES

Congratulations on selecting a Ultrasun UFD Flatplate Solar Hot Water 
System.  They  are  manufactured  to  the  highest  standards  and  if 
installed and operated correctly will give many years of efcient and 
trouble  free  service.  Careful  reading  of  this  Installation  Manual  is 
therefore important, though should there be any queries they should 
be referred to the equipment supplier.
