For things like window units and fridges, this will at least allow one of the better drop-in replacements for HFCs to be on the market. The charge size limit of 150g will still prohibit things like central AC units and mini splits, unfortunately. People are so worried about a little isobutane or propane in their refrigeration devices but we have constant pressure tubes forcing methane into many of our homes at 60psi. HCs would be great refrigerants and I think we can deal with the flammability...

The natural gas pressure at a stove inlet is supposed to be something like 0.25 PSI, not 60 like in the underground service lines. A pool boiler might need slightly higher, but in general the pressure in the building lines is very low. https://inspectapedia.com/plumbing/Gas_Pressures.php#NaturalGas https://inspectapedia.com/plumbing/Gas_Pressures.php#Natural...
