I have an oil hot water heating system, I have air in the lines but no bleeders on the baseboards. How can I get the air out.
Thank you
Jodi

If you have no bleeeders you best be calling a pro for a On Site visit. It might need to have a pressure bleed and no way with so moany different setups can I explain that here. Have them install some HIGH vents to prevent this problem in the future.
