- Technical Documentation
In a closed heating system water cannot be compressed so any increase in volume, created by an increase in temperature, has to be accommodated by an expansion vessel. When water is cold, the pre-charge pressure forces the
diaphragm against the tank towards the inlet. As the temperature increases, the expanded water volume pushes against the diaphragm creating additional volume for the water to enter. When the temperature decreases, the pre-charge pressure forces the water from the tank and back into the main heating system. This maintains a constant pressure within the heating system helping to reduce energy consumption.
Robokit Extra Vessel and Sealed System Kit
The Robokit Extra consists of an expansion vessel with a sealed
system kit which contains;
• Expansion vessel
• Wall mounting bracket
• Quattro 4 way connector
• Safety relief valve complete with pressure gauge
• Filling loop
NOTE: The expansion vessel must be sized to suit the volume
change of water within the heating system.
