No tions or djustments re required for either underfloor heting loops or rditors. Exmple 2 The indoor unit is instlled t the highest point in the wter iruit. The totl wter volume in the wter iruit is 350 l. Rditors re instlled, so use the grph of 80 C. Ations: Beuse the totl wter volume (350 l) is more thn the defult wter volume (140 l), the pre-pressure must e deresed. The required pre-pressure is: Pg = (0.3+(H/10)) r = (0.3+(0/10)) r=0.3 r. The orresponding mximum wter volume t 0.3 r is 205 l. (See the grph in the hpter ove). Beuse 350 l is more thn 205 l, the expnsion vessel is too smll for the instlltion.
