Randy—the radiant heat company (Radiantec out of Vermont) recommended a
small boiler instead of a water heater for this application. It’s actually
much smaller that a water heater that would be big enough. My target is 55
degrees in the winter. I can use portable electric space heaters to
spot-warm a workspace if I’m out there.

My house was original built for hearing using a water-sourced geothermal
heat pump, but the well couldn’t deliver enough water, even with a
3500-gallon holding tank. The house is forced-air now, and it’s not
optimal.

Ken B—the radiant floor system is actually quite cheap if installed during
construction. For 2400 square feet of heated floor, the system is a little
over $6000 including the boiler. The barn has no plumbing, so the system
will be filled with antifreeze and operated closed. The only gas I have is
propane—too expensive—not doing that at all. The foundation contractor will
install 2” of insulated panels below the slab.

When I enclose the attic space, a minisplit is probably how I’ll go. That
comes later.

Rick,
I’m extremely curious to know more about your failed geothermal system. I’m in the planning/designing stages for a well-sourced (open loop) system here at home, and have been researching the subject. Knowing more about your system might help me avoid a few issues with mine.
 
working for an underground company, I agree with Matt, you can't have enough conduits exiting the facility.

what people do forget to install, and if you are using steel siding for sure, is run a conduits for low voltage. even just a 1" pvc under the
concrete to go from one side of the building accross to the other.

I have ran conduit out of a steel building a few times to a simple telephone pole. that way, you can put a wi-fi access point external to the steel
structure in order for wireless cameras, and other items to work. have installed many weboost wireless repeaters on steel pole barns, so you have
cell signal inside.

Jon, It's a pole barn with laminated stacked 2x8 posts, laminated 2x12
beams, and wood roof trusses. The siding is steel, but thin and easy to
cut. And there will be no interior paneling or drywall--I can run conduit
along the walls easily. I'll use a couple of Ubiquiti Nanostations to
connect my internet from the house over to the barn, and can run the
network cable through a wall wiring access panel--easy for me to install.

Doing stuff in the floor is nice if you want to create a livable space
inside with drywall, etc. But this is an ag building and I'm happy to
attach conduits from pole to pole on the inside.

Trying again with more trimmage. I do not like the way Gmail makes it
difficult to trim (or even see) quotes.

Les, I can't help, unfortunately. That system was installed by the guy that
built the house in 1979, and we didn't move into it until 2002. That system
had long been abandoned. My understanding from talking to him was that the
system needed more than 10 GPM from a well, and the well couldn't keep up.
They actually ended up drilling another well, and used the old well for
irrigation. I have not used the old well in many years because the pump
needs to be replaced and I don't need it enough to spend the coupla grand
that would take. (I don't need it at all, actually, though that may change
with my new-found interest in agriculture :)

The new well flows 9-10 GPM, which is abundant for normal residential
purposes.

I've since replaced the forced-air system, and had to redesign a bunch of
it. When they retrofit it into the house, they had the evaporator coil
mounted upstream of the air handler, used inadequate filtration, and had it
mounted so the flow was going the wrong direction (i.e., they mounted it
"upright" to preserve the condensate drain configuration but the duct they
mounted it in was a downdraft return-air duct). I removed the old A coil
evaporator and installed an N-coil evaporator right above the furnace air
handler where it should be. The AC is a hybrid-heat system--heat pump
supplemented by a propane-fired furnace when the ambient temperatures are
below 36 degrees. It's efficient, but the supply ducts in the house are not
properly sized and the upstairs gets hot in the summer. Then, there's the
total lack of insulation between the unconditioned attic and the upstairs
bedrooms, even though the roof of the attic is insulated with R24 batts. I
need to close off the gable vents altogether (which aren't needed even
now), finish the interior paneling in the attic to divorce it from the
ridge vents, and then put in a small air-conditioner up there to condition
the attic space. My Covid hobby last spring was building a proper staircase
to the attic--but our house is architect-designed and it's all too strange
to describe.

Rick,
It sounds like I could learn a bit about “what not to do” from studying your house construction. Unfortunately I also live in a house designed and built by a PO. Lots of good, and lots of bad. After 27 years in the place, I’ve managed to correct the worst of the worst, and learned how to live with the rest. As I approach retirement, I’m now focusing on creature comforts as well as added value improvements.

Thanks again for sharing details.
