In this video, I show you how I was able to bleed my hot water heating system. Air was trapped in the heating lines so the system needed to have the air removed.

I basically hung on till the end to see how you use the bleeder valve. I wish that was included but I guess I'll go for it with a guess

Great info. I sit in front of my fireplace and wonder how to capture more heat. You gave me an idea what is needed and an understanding of the system. Hopefully I can put something together safely.

you juste saved me so much money!!! 3rd pump in 8 months making the same squeeking noise!!!! I had air in the system and purging it was the most easy solution but no plumber tried it before me!!

Good video. One point though: switch off the boiler and pump at the socket or switch. A lot of boilers with a separate pump keep the pump running to prevent overheating. If the pump is on while bleeding a rad, air can be sucked in through the opened bleed valve.

Thanks Andrew. You certainly answered a lot of questions I had about my propane boiler system. From my channel to yours, nice tutorial! 😀

Thanks for the video, i'm fighting with air in my lines all the time, and currently trying to track down where air can be introduced; luckily we have bleeder valves at all rads that are above grade. Noticed in your new addition the use of non copper lines, is that pex or some equivalent?

what is the reason for bleeding the hot water system? is there air in there at all times...I dont seem to have bleeder valves either and I have hot water baseboard? If t here's air do you get loud cracks and snaps in the pipes?? thx SO much

I thought you couldn't use pex pipe with copper pipe. I thought you needed pex alpex pipe. I had asked my plumbing supply guy and he had said that the pex pipe can only be used at approx 90 degrees temp. Am I hearing this right? Pex is so much easier to use I had hoped to use it. Any thoughts

I have one of these. But I don’t know if the cap is supposed to be tight or loose. Am I supposed to push the valve under the cap to release air?

I’ve been looking for the key to bleed those cylinder looking things what is it called ??
