Thanks guys,
I can buy a flat plate HX on Ebay 5"x12" 30 plate, 120Kbtu for $150
I already have a 5gal unopened propylene glycol made for heating systems.

I could sleep better doing the 30% propylene glycol in everything outside house.
Not only is it 100' from house to HP in shop, it is also 75' from shop to Solar panels/tank.

Enthalpy of fusion - Wikipedia, the free encyclopedia

Also this opens the door to the possibility of using "Latent Heat of Fusion"
(enthalpy of fusion) by allowing ice to form around the HP source HX tubes in the 1,000g Solar tank.

This would only occur after a long period without Sun, and supports the bottom end of ESWT at 0*C increasing the Solar tanks heat capicity by about 2x

I don't know if system would ever need to use 0*C ESWT as this would require my calculated economic "Balance Point" from post #1 to drop below a COP of about 5.0

BTW, has anyone checked my math?
OR
the thread idea presented?
