4-6 System Pressure
Fig. 4-6a Pressure Diagram
Notes on Pressures:-
1. The Mains Pressure Reducing Valve is not normally required on standard systems
with normal mains pressure, however, if the mains pressure is more or fluctuates
above 4 Bar a Mains Pressure Reducing Valve should be considered.
2. The Combination Valve has an integral pressure reducing valve fixed at 3.5 Bar
therefore the hot water System Pressure will be 3.5 Bar maximum.
3. If the Mains Pressure is less than 3.5 Bar then the hot water System Pressure will be
at maximum Mains Pressure.
4. The Combination Valve has a Pressure Relief Valve (PRV) set at 6 Bar.
5. The unvented cylinder has a Temperature and Pressure Relief Valve (TPRV) set at 7
Bar.
6. The heating system has a TPRV set at 3 Bar.
ELECTRASTREAM PLUS ONLY
7. The Accumulator Pressure is factory set at 2 Bar.
8. The recommended Accumulator Pressure is 1.5 Bar below the mains pressure with
an absolute minimum of 0.8 Bar - see 5-1, Stage 9. Consult GAH (HEATING
PRODUCTS) for further information.
