It sounds like you have some flavor of radiant heating in you concrete
slab which is great but obviously difficult to do after the fact. I
failed to mention it, but it takes a long time to warm up a big slab
once it gets really cold and lying on a cold surface can be VERY
uncomfortable even if the air temp is more reasonable. Fortunately
where we're located (Central Texas) the winters are very mild and
ground temps rarely get down to freezing, even at the surface.
A short story - We were living in Hawaii in the early '70s and bought
a water bed. We decided we didn't need a heater because of where we
were. We filled the bed from the water hydrant just outside or bedroom
window, and spent one of the most miserably cold nights of our lives.
We laugh about it now, but it wasn't so funny at the time. Needless to
say we bought a heater the next day! Point being it take a while to
change the temperature of large dense masses.
