6 Description and function
6.1 Description of the product
The entire unit can be packed into the two insu-
lating shells.
The advantages of system separation for under-
floor heating are:
• No muddying of the heating system as a whole
• The heat exchanger itself does not require venting
• The entire system separation is made of corro-
sion-resistant material
• The screwed connections make the system
exceptionally easy to install
• Right or left-hand installation easy
• The foam shell (Wilo-Safe) is both thermal insula-
tion and an installation aid.
The parts described below are supplied as a com-
plete system separation unit.
