How do you bleed out air from a newly installed home boiler?

Question

In September my wife and I took a plunge and replaced our 35 year old boiler. We've lived in our house for three years now and never had to worry about air in our boiler system. The only problem we had with it was its inefficiency. We had heating bills $300 and our three zones were set at 60 all winter. Since then we put a new boiler in and can't get the air out. We have 3 bleeder valves upstairs, I've been bleeding them everynight for almost a month now. I can't get the company back who installed it, they said their job is done. Can anyone give some advice as to what I need to do. I can hear air in all of my pipes. Will this eventually ruin my new boiler? Help please

Answer 1

Have a look at my furnace system and follow the bleeding instructions. Yours will likely be similar. Bleeding the system should be relatively simple.

Answer 2

Do you have an expansion tank (You should have one)

There should be a valve that isolates the tank from the boiler .

Close the valve the goes to the tank.

On the tank there should be a valve or a least a plug near the bottom
at one end. There also should be a plug near the top of one end of the tank.

Put a hose on the valve & run it to a drain.

Open the lower valve (plug) & and drain out water.

After the water flow slows down you can open the upper plug or valve. (The flow will stop & air is sucked into tank, opening the upper plug lets the water out better).

When tank is empty close valves or plugs.

Open valve from boiler.

This is a better way of getting most of the air out.

You may have to bleed some of the other valves in the line.
