[Mr. Maple]

  I have seen others post pictures of their house showing spots where the heat is seeping out of the house? Where would I find one of these without paying a fortune,and if at all possible renting might be a better option,as would not need to continually check?

If you have a smart phone these work really good at an affordable price.

If you already have Milwaukee M12 tools, they offer a FLIR gun for the same price as the FLIR Pro.

There is a SEEK thermal camera attachment for your smartphone also, a little cheaper than a FLIR but works real good.

Happily recommend the FLIR units.  A friend with an iPhone has one (he bought it in 2016 for the same purpose you want one, says it worked great), so when I wanted to anchor dividing walls to my in-floor-radiant heated basement floor, we used his phone to map out all the radiant tubing in the important areas.  took all of 60 minutes to do, and half of that was waiting for the tubing to warm up once I cranked the thermostat.  Was stupid easy to see where the tubing was, even in areas where it's 4" spacing.

Is it possible to see the tubing buried in concrete with one of these?

Yes! that's what I'm saying.  The FLIR unit was great, it shows an IR image with a visible-spectrum image superimposed; we could see every twist and turn of my floor loops.  I took a minute with a ruler and laid out the spacing of the tube heat we could see, and it was spot on for the tube spacing in the subfloor foam we used.  It was excellent.  I've got 24 Tapcon screws into my floor now, anchoring 90' of dividing walls, and there's no way I could have put those all in blind without hitting a tube.  I didn't ask him to save me an image for future reference, so I've got nothing I could attach here, but believe me, it works well.  Our floor is 3" foam with embedded trough for the tubing, and the 3" - 4" of concrete is just poured on top of that whole mess.  We used a 6" nail on the end of a stick to locate the tube on the floor (because the nail showed up like a laser beam on the IR image), then just put a magic marker mark where the tube was.

Mr. Maple,
I tried a spot gun before the FLIR camera.  Totally useless for finding the floor tubes, because you just don't have enough context to know what you're looking at.  Might help finding air leaks, don't know, but the context you gain with a 2D image overlaid with an IR image is just great.  You can even see the studs in a wall, much less find air leaks.  The only thing it was really marginal at was finding the embedded plastic studs in my ICF wall; just not quite enough temperature differential for that, though it might have worked before I put up the drywall.

Taken with a Flir.

Thanks, Coolidge.  Exactly.  Glad someone had a pic.
