Split A/C as air to water heat pump

[Natmat]

(mechanical ) thermostat cuts out at ~55c (130f) and rarely does it run above 600 psi

55c (130f) (give or take, thermostat is mechanical and at the bottom of the tank)

600 or so psi

R-22 at 600 psig head?

[Natmat]

r410, (i don't currently have the r22 system running )

[Natmat]

i mentioned i tried several different ways with varying levels of success, first i tried making my own coaxial heat exchanger with ~15 meters of 3/8" copper inside a 20 mm pex, next i tried one from Doucette Industry, both worked but need a circulating pump, so now I've made a coil from 3/8" copper, i hand roll it around the cardboard core from pallet wrap, then drill and tap the steel flange-plate found on the bottom of the water tank and seal in the spiral using compression fittings, I'll post pictures of the various things I've mentioned.
and id like to correct myself, my current system is running at about 400 psi

here are the different coaxes, and the final spiral coil
