Re: Plastic 3/4” service entrance on a brass adapter
a fusion welded socket fitting is probably the only thing that would be as strong as the pipe. a long brass barb fitting that has to be installed with heat is unlikely to fail catastrophically but may seep.
Re: Geothermal, one loop field, two air handlers
If you want to use the one fill/ purge valve for the loop and circuits, add a ball valve between the close tees.

yes, the 'shear' would be a little easier to get out of jail it seems. The 'pop' is what rattles me.

Looks like the bigger issue is someone sliding something across the floor and not paying attention shearing the pe right off flush with the floor. You could shear copper off too but it would be a lot more difficult.
Re: Plastic 3/4” service entrance on a brass adapter
Hard to tell from the pic, it could be the Ford Grip Joint fitting. The nut looks similar to a flare nut. It has a bronze gripper ring inside. That would be more common than a plastic flare, which requires the flare tool shown above.,
For plastic I prefer the fitting with the extra "gripper" collar on the outside, bottom of the pages.
My home has a black PE plastic water line with a regular copper crimp ring!

Re: Plastic 3/4” service entrance on a brass adapter
It sure looks like a flare fitting.
You can flare some PE tube. Often that service water piping is the thicker wall 160 psi version in a CTS (copper tube size) OD.
The yellow PE gas piping takes a flare fitting also.

Re: Panel Radiators
Runtal is probably the best but there are lots of lightweight european panel radiators imported under a number of brands that are also good and less expensive. Castrads makes some steel radiators that are worth looking at too. It all depends on what capacity you need, what space you need to fit it in, and what your budget is. US boiler makes some stuff that is worth looking at too although that is mostly cast iron.
Re: backflow at funeral home
It’s a good idea and a fight you won’t win. Make sure you have a properly installed domestic expansion tank installed also.
And of course you’ll probably need the BFP inspected/certified annually.
Re: Zoned system or not?
- Don't abandon the Hot Water Heating system.
- Use a 2 zone system with separate thermostats for the first and second floors.
- Try not to place any ductwork in the unconditioned attic. That ductwork will have a much greater heat loss (duct loss) exposed to the hot attic in the summer and cold attic in the winter. Enough loss to require increasing the size of the outdoor unit by 1/2 ton of capacity (6,000 BTUh)
- You can use one system with zone dampers or two separate systems for zoning.
Just some thoughts from an old man in a wheelchair with nothing better to do.
