Scheme of closed heating system
Mounting on open heating system
One of the aspects of carrying out installations is shown on fig. 6.
At this system, on initial guide: safety distribution guide of expansion vessel and
valve of the boiler are to be installed in order, and on initial guide of the system boiler
valve, pump and valve are to be installed. Directly below open expansion vessel
short connection between safety distribution guide and safety return guide is to be
installed, which on winter provides freezing of water in expansion vessel.
On safety distribution and safety return guide there may not be any armature.
Expansion vessel itself must have overflow pipe as on fig. 7. Capacity of expansion
vessel is determined as follows:
V = 0,07 x Vwater, (l), where V water is capacity of water in entire system.
Open expansion vessel is to be installed vertically above the highest heating body.
At the open heating system, gravitational heating system is possible.
