Sorry I missed your question. I don’t visit here often enough, obviously.
I’ve got 2 partners in the bldg. We’ve got enough room for work and storage of vehicles.
The hydronic heat is extremely even. Even at 45-50 degrees, it’s comfortable to work in shirt sleeves, because your feet aren’t freezing. Add a portable LP heater and it’s 70 in no time, for just a day’s use.
With the probe buried in the slab, you don’t need to worry about the furnace turning on every time you open a door for just a minute.
