This is very strange
Cavitation means no flow, can be caused by no flow / shut valves etc or dirt in the impella
My recommendation would be to split the pump and see if there’s dirt in the impella
That’s the thing though
Heating pipes are at the location so no need to alter / add these
Hot and cold just need to be run to the airing cupboard/ cylinder location in 15mm
Gas need to be there but you can’t install that
The washer either rubber or fibre needs replacing after you’ve disturbed it unless it’s brand new

As condensing boiler aim for dt of 20
So flow will be 60c return 40c
60+40/2-21
Mwat Dt29
To get conversion factor as most rad output are at dt50
29/50 xy1.3 = 0.492
Room requires 2931w
2931/0.492
So in dt 50 wattage you will...

As for zoning eg upstairs and down you don’t increase the Heatloss you just increase the demand eg downstairs will temper upstairs eg if downstairs is 20 upstairs will be around 18 if not heated

I don’t believe the ems port is usable it’s there but not fully built in
Also how does it know when the hot water is being heated it doesn’t, it’s a dumb (in wiring sense) all it’s looking for is 240v on the heat terminal
