I'm upgrading my central heating system with Thermostatic radiator Valves and an ABV.
Do you know the minimum flow rate for an old (but good) BAXI WM 381 CHB boiler set at 51700 BTU/15.15KW, the system use a grundfoss selectric 4 pump, 10 radiators and a mix of 10mm and 8mm microbore.
Or is there a standard setting that should be used or some trial and error method when the minimum flow rate is not known? The ABV is a Honeywell DU145.
Thanks, Kevin
