Can't say I know of any installed.....
However. With a heated floor, you'll want heavy insulation underneath, then 3/4" ply for the floor, with channels for the PEX piping. You'll need mixing valves, and a pump, and 110f water. VERY slow to heat a space... but, very comfortable.
Baseboard, needs 160-200f water, and a pump. Faster to heat.
I don't know what you're working with. But, personally, I'd see about a small forced air, heater.
In fact, you could also look sat something like a LP direct vent, pilot unit, that doesn't even have a fan. Works similar to baseboard heat, in that it will convert naturally. But, no power required, and won't freeze.
Just some thoughts.
