Been reading on various radiator thoughts, under my existing floor between joists, building a pex wall, etc...

What about an ON-floor radiant heat system, like a hydronic rug? If it sat under my coffee table, I wouldn't likely see any crushing of tubes underneath. Hoses could run under my couch and down to the tank and be mostly invisible ...

A coffee table doesn't have much of a footprint, and I wonder how much heat you'd get from a radiant heater that small. I think a fan-forced system might work better, proportioned to fit under your coffee table, or under/behind your sofa.

Eventually I built it into an end table:

The one shown worked pretty well, though the 55gal drum didn't hold near enough water.  I eventually scrapped the whole system, as upgrading it would have cost too much for occasional use (I live in Florida).

I should make a hydronic rug for my  poor old bald head to keep it warm in the winter. [biggrin]  I guess a furry hat will work.

Presuming I had a 4x8 storage tank, my thoughts on a hydronic "rug" as it were would just being a very flat (1/4" maybe????) 2'x4' HEX with lines that went under a runner and under the couch to a wall outlet that heads down to the hot tank.

I figured it would be a nice way to add heat to the center of the room instead of building a wall style radiator.

Though the same thing could be said about putting an under-couch unit that was similarly thin or put the couch up on a bit of a riser. Heck, with some tubing hidden in a cord hider between the couch and coffee table (realistically, there's an areas where I'd never step behind the coffee table, my "out" off the couch is in the other direction), there's theoretically no reason that both couldn't be somewhat achieved...

Not that I plan on getting rid of my newly purchased home, I'm thinking of "quick wins" would allow use of a hydronic system without the some of the time and $ sink a whole between-joist would take.

Something like a kick-space heater might work, and I think it would fit under the sofa. The're not cheap, but neither is building one.

If I were to do it again I'd simply buy one of them rather than go to the trouble and expense of building my "space heater".



Another thought might be to make something like a hydronic floor but ON TOP of the existing floor, and cover it with a rug or carpet. It would be about 5/8" thick, not counting the carpet.
