Kwikot Kwiksol Solar water heaters and solar collector panels

solar water heater type

• Direct system

  

  DIRECT SYSTEM:
  The direct system is used in frost free locations, where the ambient temperature never falls below 5° C and where the water quality is good (less than 600ppm Total Dissolved Solids/Minerals).
  The direct system is where the water to be used in the household (hot water) circulates through the solar collector panels or solar vacuum tubes manifold, transferring solar energy into the storage tank of the solar water heater.
  The direct system can be installed as a Split System (pumped or thermosyphoned circulation methods), where the solar water heater is installed inside the roof or away from the solar collector panels or solar vacuum tubes, or installed as a Close Coupled System (thermosyphon circulation), where the solar water heater is installed outside on the roof and above or higher than the solar collector panels.

  DIRECT SYSTEM:
  The direct system can be used in frost and frost free locations and where the water quality is good (less than 600ppm Total Dissolved Solids/Minerals).
  The direct system is where the water to be used in the household (hot water) circulates through the solar vacuum tubes manifold, transferring solar energy into the storage tank of the solar water heater.
  The direct system can be installed as a Close Coupled System (thermosyphon circulation), where the solar water heater is installed outside on the roof and above or higher than the solar collector panels.

• Direct low pressure system

  

• Indirect system

  

  INDIRECT SYSTEM:
  An indirect system is where the potable water used in the household (hot water) does not circulate through the solar collector panels, but remains in the solar water heater and is heated through a heat exchanger around the vessel. Propylene glycol is circulated through the solar collector panels, transferring solar energy into heat exchanger and in turn heating the water in the solar water heater.
  The potable water and propylene glycol never mix and are held in separate chambers within the solar water heater. The tank and solar collector panels are connected together with two copper tubes, which are used transfer heated propylene glycol from the solar collector panels to the storage tank heat exchanger. Propylene glycol does not freeze and therefore protects the solar collector panels from freezing damage in frost prone areas.
  The indirect system can be installed as a Split System (pumped or thermosyphoned circulation methods), where the solar water heater is installed inside the roof or away from the solar collector panels, or installed as a Close Coupled System (thermosyphon circulation), where the solar water heater is installed outside on the roof and above or higher than the solar collector panels.
