2.6  Pressure loss and head 

The following diagrams show the primary circuit pressure loss according to the ModuSat 
equipping and the head feature head available to the apartment circuit. 

The head available for the apartment circuit is given by the difference between the pump 
head and the ModuSat pressure loss. 

The ModuSat ensures that the heating and the production of hot domestic water can be 
achieved simultaneously. Due to the low heat losses required in modern homes by 
ensuring that enough power is provided to meet the domestic

 

hot

 

water

 

requirements

 

it

 

will

 

make

 

it

 

possible

 

to

 

determine

 

the

 

primary

 

flow

 

necessary

 

for

 

each

 

apartment.
