P-K DURATION II 

™ Indirect Domestic Water Heating System

3.4.5 

Example Domestic Hot Water Installation 

It is important to note that the P-K Duration II indirect domestic water heating system does not require a domestic 
water storage tank, if hot water is constantly available for the 3-way valve. If using in conjunction with a boiler, the 
initial call for heat takes  time until  the boiler operates at maximum power. If the unit  is used  in  this manner, the 
storage tank needs to be sized appropriately for the application.
