I had a problem with a day care dog turning over the water bucket. Everyday they'd go all afternoon without water cause he'd turned it over. Me, being smarter than a Lab wired the bucket handle to the faucet. Tada! Came home, the backyard is flooding, the faucet is on full blast. How fun was that jerking that bucket around AND turning on the faucet? Ok yes, it was a blonde moment.

Outlets are feed one after another from the permanent wiring. The receptacles themselves are sometimes used to make the connection between the incoming power wires and the outgoing power wires to feed the next receptacle. A loose connection on these wires could cause the outlet itself to get warm.

This rock makes a statement in the garden. the light makes you feel all warm inside.

Insulation is what keeps the slab at 70, and not a ground coupled 55. So insulation helps a great deal. But the floor will still feel cold to bare skin without a less conductive surface on top of it. The reason a 70 degree concrete slab feels cold isn’t because of a lack of insulation. It has to do with thermal conductivity. It’s a large thermal mass that is cooler than your body, and it’s highly thermally conductive. It can quickly absorb the heat from your bare feet, away from your feet. Put wood over that concrete mass, and even a .5 R value, plus the lesser thermal conductivity, makes the floor feel “warm”.
