What is glowing in the basement?

Not that I've ever seen, that's for sure. The lines are copper tubing, less than 1" not 2", covered in black foam insulation on the low pressure side and how can PVC glow? No idea what you're looking at.

Sounds like a light behind a PVC pipe lighting it up.

Okay. Just like my house that's 40 years old.

She also has a backup generator. I don't see why they would use PVC pipe, or two of them, but....????

She has solar panels in the yard, but again, why PVC and why two?

She has some other gizmos too. They first owner was an architect who was into gizmos.

Good question.

Maybe the demons are decorating early for Halloween.

She lives fairly far away. Maybe I'll get her to show me where the pipes go, or maybe I'll figure out how to post the pictures here. I should learn how to do that. (I signed up for one of those services. I have to figure out which.)

Interesting. When you mentioned 2 PVC pipes, I immediately though about the combustion air lines on a high effeciency gas furnace. I know you said heat pump, but maybe the back-up heat is gas. Regardless, that still doesn't explain the glowing. Sun shining on a nearby section of the pipe is the only answer I read so far that makes sense.

Look at them again when you're sober and maybe you'll figure it out

I finally learned how to post something.

Had to get it from my phone to my phone's email to my pc to imgur.

I'll ask but I think her basement door faces east and this happened around 5PM.

Those pipes are the air intake and exhaust for the furnace. It looks like the sun shining into it from outside. Call the fire dept to be sure. Good grief.

I have seen PVC plumbing stacks that looked like neon tubes, just from sunlight coming down them.

Just looks like sunlight hitting the intake or exhaust pipe where it exits the house wall , the pipe is somewhat translucent.

How strange. I guess that's all it was. She's lived there 4 years, spends quite a bit of time in the basement, never saw it before.

Thanks all.

It might only do it a few days per year when the sun lines up just right and it isn't cloudy that day.

Sounds kinky. Does she have an S & M dungeon down there?

Oh, of course. Unrelated to where the door is.

So the light comes from inside the pipe. Weird. I don't go there more than once a year. I hope I remember to look at the pipe when I do.

Yes, you're right. And most of the time she's down there is on cloudy or rainy days. (She walks outside 4 or 5 days a week, at the mall when it's cold, but sometimes just in the basement.)

I was going to have her get a mural painted on the basement wall that would be like the roads and streets she walks on, plus a recording of traffic and bird and cow noises. But she hasn't done that yet.

I can only come over once a year because she needs notice to clear out the dungeon before I or other visitors get there. She has a service that takes them to someplace in northern New Hampshire. But she doesn't know I know.

I read about one guy who was practicing for a cross country bicycle ride. He had an exercise bicycle in the basement and would go down and ride it for hours in the dark. Said he was getting ready for North Dakota.

I like biking but watching the same damn grain silo slowly getting bigger for six or seven hours must suck.

Exactly. I don't know much about heat pumps. It is too cold where I am to use them. But those PVC pipes look like the furnace is a high-effciency direct-vent unit.

Don.

Can't be high efficiency, those pipes are glowing red.

Yeahbut. Glowing hot pvc pipes would melt and deform.

Duh.. Wooosh!
