Staging of boilers
Staging of boilers
(OP)
Hi
I am loking at staging the boilers in a system 3 boilers 3 pumps constant flow system based on either firing rate of the boiler or on return temperature.
Can you tell me how this is actually done control wise..
I was thinking if the lead boier is ay 90% fired up start the next boiler. If both boilers are then say 90% fired up start the next boiler. however I dont know ho this could be done in reverse especially all 3 boilers are different sizes.
Can this be done off the retun water temperature>?
