Gas boilers and oil boilers cycle, so why not heat pumps? Heat pump cycling is to be expected in the shoulder months, when the OAT can go from 5C to...
No problem. So the limiting factor as far as flow rate is concerned could be the valve or the 22mm pipe.
Based upon the setting of your WC curve, the calculated flow temperature should be 29.6C.
