Hydronic Floor hot spot 110F surface

Just purchased a house this summer with hydronic radiant heating on the main floor. It seems to be working fine but I’m still trying to make sense of it. Tonight I noticed a hot spot in one area with surface temp of ~110 with the rest of the floor around 85-90F. Attached are some pictures of the setup. Any advice or guidance is greatly appreciated

Pretty weird if they're all coming off the same tempered loop. Show the boiler piping.

Pictures attached. From what I understand. Anything without a zone valve on the manifold will heat whenever the indoor sensor is not at set point and the others will open based on the wall thermostats0

You find A hot spot? Do you have an autofill on that system? I'm suspicious of a leak.Br. Jamie, osb

Yes there is an autofill. I checked the basement below the hot spot and no sign of moisture0

Possibly tube bunching where they eminate from. Looks like someone tried to do a quasi European design (constant circ, outdoor reset). Without seeing an IR picture, its hard to say. Got FLIR?

If you look at the first picture, there are zones labeled Great Room #1 and Great room #2. Under this setup will Great room #1 get constant flow based on the indoor sensor?Mark Eatherton said:Possibly tube bunching where they eminate from.
