Thanks to the innovative combination of crosslinkable PEX plastic liner and glassfiber filament windings, working pressure of the reservoirs of UniQube hot water tanks is 6 bars!
There are several important advantages:
1. Reduces the initial investment. Comparing to 3 bar heating system, the 6 bar heating system requires approximately 2 times lower volume of the expansion vessel.
2. Improves system stability. It absorbs short acting pressure peaks.
3. Integration in the big heating systems. Pressure resistance of UniQubes makes them suitable for heating systems where there is notable height between the boiler room and top heat consumer.
