A typical plumbing schematic connecting 3 x 1200 boilers together.
NOTE the increase in pipework sizing to ensure proper ow through the boilers.
Ensure there are no restrictions in the heating circuit such as thermostatic radiator valves etc.
Expansion vessel etc. has not been shown on this schematic.
For 2 x 1200 boilers, 28mm pipework ow and return is required.
A bypass must be tted. Preference should be made for a 600 x 600 radiator.
