INTRODUCTION   TO   SEISCO

   

   

Congratulations   on   your   purchase   of   the   

   

SEISCO

®

   ON-­‐DEMAND   TANKLESS   WATER   HEATER

   

   

You   are   now   in   a   rapidly   growing   and   highly   discriminating   group   of   individuals   and   businesses   that:   

Prefer   the   freedom   of   managing   ones   own   lifestyle   through   technologically   advanced   equipment   

Have   the   need   and   desire   for   hot   water   WHEN   they   want   it   from   an   ENDLESS   SUPPLY.   

   

No   more   waiting,   no   more   running   out   of   hot   water.   

   

Early   civilization   relied   on   hot   water   springs   to   supply   all   the   hot   water   needed   for   cleansing   and   for   

therapeudic   purposes.      However,   as   civilization   progressed,   the   accepted   method   of   producing   hot   

water   has   become   restrictive   –   the   storage   tank   water   heater.      We   have   become   conditioned   to   the   

statement   “We   can’t   do   the   laundry   after   the   family   showers”.   Or   in   the   winter   months,   “I   have   to   

wait   an   hour   for   enough   hot   water   to   take   my   shower”      

   

For   the   past   70   years   little   change   has   been   made   in   the   most   common   water   heater   delivery   system,   

the   cumbersome   inefficient   storage   tank   heater   that   still   delivers   only   a   LIMITED   SUPPLY   OF   HOT   

WATER.      Even   the   classic   flow   through   water   heaters   around   since   the   Victorian   period   are   

inherrently   inadequate   for   the   lifestyle   enjoyed   by   most   of   the   Western   world.   

      

Only   in   the   past   several   years   has   technology   advanced   to   the   point   that:   

Metal   parts   used   in   demanding   applications   can   be   replaced   with   glass   fiber   reinforced,   heat   

stabilized   nylon   resin.   

Micro-­‐control   has   reached   a   new   high   level   of   speed   and   proficiency   

   
The

   SEISCO

®

   

uses   a   patented*   technology   that   combines   and   implements   the   best   of   both.   

   

Only   SEISCO   has   been   able   to   develop   a   water   heater   that   is   inherently   highly   energy   efficient,   modular,   

rust   free,   scale   resistant,   and   endlessly   responsive   to   the   varying   demands   of   flow.   

   

The   development   of   such   a   system   was   no   small   task.   Your

   SEISCO

®

   heater’s   patented   technology   

represents   the   culmination   of   over   10   years   and   millions   of   dollars   of   intensive   development   and   testing.      

We   have   outlined   what   we   think   are   major   benefits   in   this   manual.   After   reading   the   manual,   YOU   

DECIDE   which   is   the   most   important   to   you.   

   
Congratulations   again.   We   know   you   are   already   beginning   to   enjoy   the   benefits   of   your   new
