Combi tank HYG B - without coil 

To  produce  and  accumulate  sanitary  hot  water  and  hot  water  for  space-heating  system.

Coil-in-Tank  construction- Flexible  stainless-steel  coil  for sanitary hot water + Buffer tank powering space-heating system.
Sanitary water heats  up  instantaneously  as  it  flows  through  the  large  surface  stainless  coil. Thus  water  is  delivered  hot  while  still  fresh  and  clean  of  depositions. Allows  utilization  of up to three external heat  sources  and  an  optional  electric heating element.
