Actually, do either vertical or horizontal insulation mut both is just a
duplication.  The horizontal installation can also be just as effective if
it goes away from the building.  Think about it!

Justin , insulated floors on slab in a shop?

Do it.

Especially make sure that the perimeter of the building is insulated as that
is where most of the heat loss will be. After a nice thick insulation
(vertically) below the frost line at the edge and maybe four feet in
(horizontally), a well drained gravel bed is almost as good as continuing
the insulation. The largish gravel isolated from the cold by the perimeter
insulation will stay relatively warm and not transfer heat real well.

With the possibility of floor mounting new equipment and vibration from
same, I would not be as enthusiastic about in floor heating, even though it
is comfortable..

If you are heating with wood and feel comfortable designing a system like
the Romans used (hypocaust??) it might be fun but expensive.

Depending on layout, you might want to think about radiant heat at the
ceiling, over key areas.
