Any HVAC guys here?
« on: October 11, 2013, 03:29:06 PM »
Have a quick question for any hvac guys here, i have a 4 zone system, its a boiler with baseboard heat......One zone isnt getting warm, and im thinking its because of air in that line....now i can bleed the lines, as every zone has a seprate bleeder valve in the basement.....question is, should the heater (thermostat) be off or on when i bleed the baseboard heaters?

on you want the water flowing to move the air, if its not air thats causing it it may be the zone valve
Its better to sit in a boat and think about God, than to sit in a church and think about fishing.

Are zones controlled with single pump/zone valves or single therm/pumps for each zone?

We need to know that...

I have 3 zones with three pumps...no zone valves..

If you have zone valves on yours you will have to manually turn them in the on position to bleed them...

You can also manually open the valve to see if the the heats works on that zone. If it does then look at the control side of that zone. It may not be air, but a stuck zone valve or the coil on the valve.

Fishing Sandy Hook and anywhere I can get on a boat.




My biggest fear is when I die my wife sells all of my fishing tackle for what she thinks I paid for it!

hey! bleeding a hydronic system is best at the high points furthest from the boiler. Pull your covers and see if there is a bleeder(in the living space)
