Sizing of safety equipment
Expansion vessel sizes are relative to the volume of liquid in the system. Therefore it is
important that the Thermomax ‘Technical Design Guide’ is consulted for each system.

When selecting a vessel for intermediate sizes, the vessel should be selected by rounding area up to nearest m². All sizes above
are calculated based on a 17ltr system volume as an example. For larger volumes the expansion vessel size should be recalculated.
Cooling vessel sizes are dependant on pipe dimensions and can be calculated on a case by case basis or selected using the table
above as a guideline.
* figures marked as such are estimates based on other measurements
Cooling Vessel
(only required with DF systems)
It is strongly recommended that a cooling vessel is used with the DF collector to
protect the expansion vessel from stagnation temperatures.
