You say 1 st time home owner. Have they ever worked ?? Do they work off the same circulation pump ?
Then, yours were installed WRONG.I haven't seen a bleed valve on baseboard radiators?
I don't have baseboard heatersThen, yours were installed WRONG.
Each baseboard, should have one baseboard ell(not a regular 90° ell), with a bleeder installed in it.
Thats why their installed wrong.I don't have baseboard heaters
So they couldn't be installed wrong :thumbsup:
