Currently staying in a condo. A particular spot on my floor feels quite warm or hot, but the surrounding tiles have no such problem. I'm suspecting the spot to be where lighting is installed at the unit below. But is it normal to be able to feel the heat from lighting below through the floor???

yes, same with my house.

solution: i put carpet/bamboo carpet, so the heat didnt feel much.

This is a bit late, but thx for the reply. I'm using a floor mat now. In a positive note, it's extra "feature", heated floor
