Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of your situation.

What's your question? "Bleeders" on copper baseboard are completely useless.

my heat in the house works then stops hes telling me that it has air lock again never had this problem before the new heater was installed why
HVAC Technician: Rick, HVAC Supervisor replied 4 months ago

If it was purged properly there should be no air lock. Is the boiler hot when the heat stops? are the pipes hot?

HVAC Technician: Rick, HVAC Supervisor replied 4 months ago

If the pipes are hot how can the heat stop? I've been at this for 12 hours today. I'm out of gas. This is going to take some extended trouble shooting. I can pick this back up tomorrow. I'd suggest you cancel tomorrows service call and we can spend some time figuring this out. I'm back online at 9 am ET. If you need an answer tonight you can opt me out but there are no other experts here with my 45+ years of experience with hot water systems.

well i think i figured it out
Customer reply replied 4 months ago
i think the valves are in backwards the taco valve has an arrow on it correct and the arrow indicates flow correct if the arrow faces down on the upper level pipes thats why they stay warm and the arrow is facing the opposite way on lower level mind u i have one thermostat the valves are in bypass
Customer reply replied 4 months ago
the arrows should be facing the flow of water to the baseboard right
Customer reply replied 4 months ago
hello u there
HVAC Technician: Rick, HVAC Supervisor replied 4 months ago

I'm back. Let me know if you want to proceed.
