Ok guys , ive got this system running as best as it can.
I had a desuperheater before the condenser , i was heating a 300 litre cylinder over night to 65c but the underfloor was not getting up to temp as much as i wanted on cold mornings.
After using coolpack and running the info i had i found i had a massive pressure drop through dsh ( i didnt have a high side service port to attach to before dsh) .
I was using 3kw at 40hz and could not run it any faster as it was near max amps.
I bought a sporlan ORI 6 and cut it in to bypass the dsh , now i can run it on full bypass of dsh and condense at mid 30c .
It will now run 55hz and uses 2.2kw .
COP is between 6.4 at minimum and 4.9 at maximum not including pumping .
So pretty happy with the changes.
