Help a girl out here, please!
In the last week or so (with the returning heatwave) I've noticed a very warm patch under my upstairs hallway carpet, it almost runs along the hallway and into the bathroom, as if it is a pipe. Problem is, when I google it this comes up with alot of results relating to actual underfloor heating- this is not.
Has anyone experienced anything similar, what is it and is it a cause for concern?
