Solar hot water showers Solar hot water showers Presentation Transcript

  • ! SOLAR  HOT  WATER  SHOWERS  
  • If  you  have  an  electric  hot  water  system  for  your  shower,  it'll  be  responsible  for   up  to  1/3rd  of  your  household's  power  use.  Tap  into  the  heat  of  the  sun  with  a   solar  hot  water  system  which  is  likely  to  be  the  single  most  effecAve  move  you   can  make  to  save  power.     Solar  shower  systems  use  energy  from  the  sun  to  heat  water  at  zero  cost  and   produce  no  carbon  polluAon.  While  they  cost  more  to  buy  than  electric  or  gas   water  heaters,  a  solar  hot  water  system  will  pay  for  itself  depending  on  your   household's  hot  water  use.    The  idea  behind  solar  showers  is  rather  simple.    You   can  use  the  sun  to  raise  the  temperature  of  water  enough  to  make  showering   comfortable  and  convenient.  
  • Flat  plate  solar  collectors  are  an  energy  efficient  device  for  heaAng  the  water  for   showers.  A  black  reflector  plate  at  the  boJom  of  a  narrow  reservoir  is  uAlized,   which  is  sealed  behind  a  glass  or  Plexiglas  cover.  The  heated  water  can  be   reserved  in  a  holding  tank  in  the  same  way  as  a  whole-­‐house  solar  water  heater.       This  type  of  solar  water  heaAng  technology  is  more  finely  engineered  to  produce   significantly  greater  temperature  increases.  Solar  showers  that  are  integrated  into   heaAng  systems  are  capable  of  increasing  cold  weather  water  temperatures  to  a   saAsfying  comfort  level.  Many  of  these  units  feature  an  integrated  electric  heaAng   element  to  supplement  the  solar  generated  heat  on  days  with  reduced  sunshine.                           A  high-­‐efficiency  solar  shower  that  draws  its  water  from  a  flat  plate  collector  is  a   safer  choice,  because  it  is  likely  to  push  temperatures  over  100  degrees.
