Low  start‐up  water  pressure  –  the  minimum  working  water  pressure  can  be  as  low  as  0.02MPa  with  an 
approximate flowrate of 3Lpm which is ideal for regions with low water pressure.   

 

Artificial  intelligent  &  power  off  memory  function  –  when  the  water  heater  is  restarted,  the  last 
temperature setting will be recalled. 

 

Multiple  safety  protections  –  automatic  error  detector,  flame  failure  device,  dual  gas  valve  safety  device, 
strong  wind  pressure  protection,  incomplete  combustion  detection,  delay  ignition  cleaning  system,  over 
heat protection, anti frozen protection (anti freezing models only)
