Balance each loop with gate valves
I will balance each loop with gate valves (or any ideas?) on the return manifolds, using temporary temperature gauges clamped onto each return pipe to get even return temps. I will put stopcocks on the input valves =
for isolation purposes.I intend to only use the in-built boiler pump to circulate the heating, and
use the in-built boiler water temperature thermostat and timer to control the room heating temperature.
I can will make allowances to retro- fit TRVs in each room if the room on the upper floor loops only If heating is uneven. But I intend to have the heating on in all rooms constantly from November to April
Q.1. Do I need to put in any Automatic Airbleed Valves on the Control Valves upper storeyloops, (If so where should the AAV be positioned -Just before the return pipe goes vertically down to the manifold to catch the air?)Or does the UFH water have enough pressure force the bubbles down to the ground floor manifold AAVs.
Q.2. Do I put AAV
