Anyone know why my garage floor would have a warm spot that is about 12 degrees above ambient? The area is about 1 foot in diameter.
It’s not from cars or sunlight. The garage floor is a slab. I have detected no water leaks.
I measured the warmth with an infrared temp gun. The warmth is there day or night.
My house is all electric. No gas. First thing in the morning, the warmth is still there.
What could be making that one little area warmer than the rest of the garage floor?
Thanks in advance,
