Energy Kinetics Air Bound or Partially Blocked Loop

Some baseboards or radiators are hot while others remain cold within the same zone.

Possible Causes

Air trapped in piping, Partially closed valve, Sludge or debris in loop, Incorrect piping pitch

Safety: Use caution when bleeding radiators; water may be hot.

1. Bleed high points: Open air bleeders on radiators or high points in the loop until water flows steadily.
2. Check valves: Ensure all manual valves in the loop are fully open.
3. Purge loop: Use the purge valves near the Energy Kinetics boiler to flush the affected zone if equipped.
