Bleeding a boiler well system

ScubaJeff

Hello pros. I have recently purchased a cottage with a well and boiler heat system. I hear the pinging so know the system needs bleeding. Watched several YouTube videos and thought I was in good shape. Turn off furnace, close return, hook up hose, start draining. Only a bit of water comes out into my bucket. No fast fill since I'm on a well. How to I do this? I'm nervous that my system won't refill itself since I'm not on city water. There is a hose attachment below my pump. Any help would be appreciated.

I see you are trying to bleed one of the zones . Normally you bleed out the air if you hear running water or no heat . To bleed that zone , close the valve below the hose and manual open the zone valve above with the lever on the zone valve .. . There should be a bell shape valve ,on 1/2". pipe called a pressure reducing valve . You want to make sure the valve before it is open .

Can you post a picture from farther back?
What does the boiler gauge read?
That flat plate heat exchanger looks like a "creative" hot water heater.
Do you have pressurized domestic water from the heat exchanger?
You should be nervous, the system should be full of water and under pressure.

The fact that you are on a well doesn't affect the purging process. It does mean that you really need two expansion tanks, however, as it looks as though there is a heat exchanger for the hot water -- so you not only need the one to control the well, but one for the boiler.
