Warmth From Neighbours?

[Alec_t]

Have you tried measuring the temperature over a grid of points on walls/floors and plotting the results to make a thermal map? The heat gradient should indicate the direction of any heat source.

No I haven't. That sounds very complicated?

Easiest with a IR contactless thermometer, if you can borrow or buy one.

Get a sheet of graph paper, or download and print one, or simply draw lines on a sheet of paper, 1cm square would be best.

Divide you wall into lines 500mm apart horizontally, likewise 500mm apart vertically, which will produce squares all over your wall. You can simply do it without marking the wall, by simply measuring where the centres of the squares are. Measure the temperatures at the middle of every square and write the values in the appropriate square on the graph paper. No point in trying to do this on a sunny day, with the sun streaming in the window, warming the wall up - you will get increased temperatures where the sunlight lands.

Reproduce the temperature values you have noted, in a follow up post to this.

Thanks for the advice. I'll ask my Son if he can do this. Far to complex for me I'm afraid!

Maybe a ghost?

I always thought that ghosts produced cold spots?

The laws of thermodynamics would suggest that if a cold spot was created, then that heat must move somewhere...

You mean ghosts at t'other side of wall causing cold and the surplus heat passing through the wall to the OP.

OP may need a medium, rather than an IR thermometer

I've given up trying to trace the source of this for now. I have to say though I was a little 'under the weather' a few days ago and, although I had the shivers, my feet were sooooo warm from this phenomenon. A bonus from wherever it may be coming from?

I'd be inclined to acquire a thermal camera from someone/somewhere which will enable you to see the hotspots.
