Squealing when heat kicks on

in THE MAIN WALL
We’ve recently noticed that when our heat kicks on, we have radiant heating, that there is a squealing throughout the house that we can’t hear in the garage with the furnace. We live in a ranch style home and though we can hear it throughout the house it is most prominent in the master bedroom/bathroom at the other end of the house. Any ideas what could be causing it?

    All you got is squealing thru the house? Did you go to where the boiler and circulators are to see if you can isolate the sound from one of the circulators or one of the components?

    There was an error rendering this rich post.

    @STEVEusaPA Yes. Everything is in the garage and you can’t hear it at all out there. I don’t know if it’s the radiant heat or the water pipes. We’ve been here almost 7 years and this is the first time we’re hearing it.

    Gotta try and see what’s making the noise. Kill the flow- does it go away? It’s the system or the boiler, shouldn’t be too difficult to figure it out if you have time to sit and watch. If it’s completely intermittent- that’s a wicked pain

    Don't know but give the boiler gauge a look the one that shows temperature & pressure.

    Pressure should be 12-15 cold maybe 20 when warm.

    If all it heats is radiant the water temp could be 90-120 or so

    UNO can easily be transmitted through pipes and be hard to pinpoint. Movement from pumps, water through pipes, orifices/ valves. What changes affect this? Passing a fluid though an orifice, friction on a moving part. So its either mechanical movement, a pump, or fluid velocity powered by a pump. Could it be a coincidental thing? UNO. Unidentified noise object!
