Figure 2 illustrates the actual fractional energy savings (fsav) to the maximum theoretical value FSC, based on annual in-situ measurements of the same installations illustrated in Figure 1 (measurements from Austria and Sweden are not available).
Comparing the actual fsav to FSC gives a good indication of the effectiveness of a combi system; the closer the fsav is to FSC, the better the combi system converts the usable solar energy into real auxiliary energy savings.
For a small ratio of storage volume per unit gross solar collector area, the heat storage capacity is too low leading to a poorer collector efficiency and consequently a lower fsav. This is illustrated by installation (0.48, 33.2%) with a ratio of 64.7 lt/[m.sup.2] (0.21 [ft.sup.3]/[ft.sup.2]).
