INSTALLATION
Example:
- Installation: 100 litres
- Domestic hot water tank: 5 litres
- Boiler: 16 litres
- Total water capacity: 121 litres
Conditions: Using a vessel pre-loaded to 1 bar
(under floor boiler = ground floor hea
-
ting + 1 floor), heating safety valve
calibrated at 3 bars, installation filled
cold at 1 bar.
- Vessel efficiency calculation (R):
+ 1) = the transformation of relative pressures into abolute
pressures
- Calculation of the useful capacity of the vessel
(Cu):
- Calculation of the real capacity of the vessel (Cr):
