well i guess the main reasons why i was thinking about going this route.
1.flammability
2.could theoretically run a higher pressure to heat H2o to keep the C.O.P higher? or do i have that wrong?
say run it at 210psi thats in the 130F range. as the water heats up to 120 you could shot it off to keep the Delta T higher?
i think i had another reason but i cant remember what it was
