Radiator hot water supply

Ghynes440

we just moved into a older home over a month ago and we quickly realized the back of the house (kitchen, bathroom and laundry room) do not get heat. The rest of our radiators heat okay. I think some balancing can be done. But what I found is the kitchen radiator has a supply on top? All the other radiators have a supply on the bottom. This radiators top side gets hot but the bottom is cold.

The kitchen radiator shown must feed the bathroom, doorway and laundry room but none of those supplies get warm at all. The problem is there is NO access underneath. The crawlspace in the basement we can see the one feed going into the stone but nothing coming out. They must have torn up the floor and fed and the piping under there and then put flooring over everything which SUCKS.

Any ideas why the top side is hot but nothing at the bottom? Sludge?

can we see your boiler, and devices, and the piping around it, floor to ceiling,?

what do you see for pressure? picture there also,

here are the pictures.

It’s hard to tell with the last photo, but that’s the lines that go into the stone and there is no access to them after that. I just noticed if you look above the threaded pipe you’ll see a green copper pipe, I assume that’s the supply that’s feed the said radiator in my first post.

when the heat is on, do you hear the water trickling thru the system? thru either the working or non working radiators?

the tank over your oil tank is your air separation / expansion tank, the way it's piped is not correct, that pipe into the tank must pitch back down to the boiler so air can flow up to that tank, what you have can't work, and air is likely trapped in the system and blocking flow,

can you post a wide shot from the boiler to that tank showing the connecting pipe ? where does the tank connect to the boiler or the rest of the system piping ?

Water pressure is OK.

If that one green copper pipe is the radiator supply, where does it connect to the other supply pipes coming out of the boiler?

That pipe looks kind of snaky. If there are any "humps" in it, air may be getting trapped in the hump and preventing circulation.

I imagine that radiator will be hot from top to bottom with enough run time, just from conduction.
Removing the plank on top will allow more heat transfer.

Unless someone thought it pushes the heat down through the radiator🧐

On some Flir cameras you can adjust the color bar on the side when you take pics. The bottom of that radiator may be much warmer than the space temperature of 60, maybe a door on the far left? so it is emitting heat. The black color is 60F

Is there a kitchen sink or bathroom above that inaccessible area? the copper kind of looks like it is probably hot and cold potable water.
