If the system volume is known, expansion vessels can be sized with the formula:
V = eC / (1 – (p1/p2))
V The total volume or nominal size of the expansion vessel. It is not the acceptance volume. (See product description).
C The total volume of water in the system (litres).
P1 The fill pressure of the system in Bars absolute (atmospheric or gauge pressure plus one Bar).
P2 The setting of the expansion/pressure relief valve in Bars absolute (atmospheric or gauge pressure plus one Bar).
e The expansion factor that relates to the maximum system requirements.
| Expansion factor ‘e’ | Temperature °C |
|---|---|
| 0.0324 | 85 |
| 0.0359 | 90 |
| 0.0396 | 95 |
| 0.0434 | 100 |
