bleeding air out of baseboard heating system

[MOXJO7282]

So we continue to hear noises in our heating system and checked out youtube and did find a good video but like many its not an exact match to my system and I just can't seem to figure it out.

My problem is in all the videos it shows a simple switch you move to change the waterflow from auto to manual so the water flows continuously so you can push the air out. Of course my 5 year system doesn't seem to have this simple switch and I drain the water and it doesn't continuously flow to push the air out. So damn frustrating that I'll probably have to pay the company that installed the unit to come back. Part of me thinks they didn't include so they have a hook in me so I'm trying to figured it out and understand why i don't have that switch.

I know it's hard to provide diagnosis without seeing my system but hoping someone ran into the same thing recently or we have a plumbing pro among us but I'm at my wits end trying to figure this simple thing out.

Thanks in advance for any help that can be offered.

The hot water baseboard heating system in our home of 32 years always had that noisy, banging issue. My husband never wanted to bleed out the system. Not sure why- just lazy about it or didn't really know how and wouldn't admit it.. I finally got him to have the boiler guy take care of it one time. But it went right back to the same ol' and we lived with it all those years.

When the boiler guy did it he tapped into the pipe on the baseboard and drained out the water with a hose and bucket or something like that. Can't remember what . Sorry I am no help.

(We also had him reverse the way the water flowed around the house from starting at the south end to starting at the north end to heat up the north facing rooms faster.

Every radiator if the pipe goes up and back down is an air " trap"
If set up right you will have bleeders at registers to get the air out at ALL high spots. It costs a lot of money to do it right. Along with fast bleed fill system. You might be set up but it's not that easy. If it's not done right it won't work. Many don't set it up right because it's not in the budget.
Noise does happen do to expansion and contraction
Got to love Utube.
A good working boiler system "easily serviceable" is a work of art, rare!

Years ago I had a baseboard hot water heating system. There was a little valve at each register and you just opened it to "bleed" the air out, very easy to do.

Yes my system was not set up properly to make it easy. When it was done I wasn't smart enough to challenge the installers to do it right as opposed to doing it that is least costly to the installer. I did figure it out to some degree and thought i was on my way but then as I was running the water at high pressure through to expel the air the overflow value triggered for some reason and gallons of water were released so my easy effort turned into a nightmare at 1am with me having to shopvac it up. I have no choice now but to pay for something that I'm sure is something that is relatively easy but because I've never done it before it becomes a major headache.

Such is life.

If it's not done right it will be a pain , and impossible for any of us.
We come to try working with what you have, it still making noise, your unhappy.
Could tell them what you want to be able to do, get an estimate , decide if you want to do it.

You should have an autobleeder on the outlet line automatically venting out air all the time because every Time you put water in the system you are putting in air. Air is in water. When the boiler reaches 180 degrees the air will separate needing vented out.

Not a utube fan, some things are best left to the professionals.
Give your plumber the ok to modify updates needed to make his and your life easy. Than let him show you how to "fastfill" your system. By doing so it helps cut down on time needed for the plumber to be there. You should never have to do this once it is set up unless your having a broblem. Boilers have problems your plumber should show you what to look for to nip them in the butt.

Sounds like you added air to the bladder pressure tank , this is how the water is maintained to the boiler (12#set) The relief valve is preset for 30# and pops off when to much water is in it.
