The picture raises questions. If that is glowing due to heat, then something bad is happening. But maybe it is a bright light in a translucent pipe or something?
For a couple of days a year the plastic flue above my boiler does this - from the sun hitting it at the perfect angle. (Source: once thought my boiler was about to blow up.)
Those don’t look like PVC fittings, so I am guessing it is a metal pipe. The minimal loss of light at the overlapping sections and how it fades makes me think that it is truly incandescent.

Likely a cast iron pipe that has grounded an electrical current. It is in fact, “something bad”.

Looks like a bright orange light is shining from below, but I favour the impossible explanation tbh
If it were that, I would expect to see a lot of orange light spill on the ceiling, and a clear shadow of the pipe.
Well, there is light and shadows, but you are right: they both would be much stronger, more clear.
Think sunset coming through a window
I’m going to need you to tell me what kind of pipes you think pipes are made out of…
