I have a combination boiler with 3 zones.
Zone 1 on the bottom floor heats up quickly. This loop is 180 feet.
Zone 2 on the middle floor heats quick. This loop is 100 feet.
Zone 3 on the top floor heats slowly and pipes coming to and from boiler are cooler than the other pipes and not much heat coming out.
I tried making zone 3 the priority loop and still no strong heat. There are no zone valves in the system.
Do I need zone valves?
Would a manifold help to direct the flow of hot water to zone 3?
Can I get more heat to zone 3 by changing the supply pipes?
