Does the diverter in this boiler default to hw or heating. Got one today hw works but on htg boiler has no circulation. Suspect diverter - merchant quoted £185 plus vat for diverter

I'd guess heating

how strong is the pump, sometimes pump can be okay on water but not strong enough to get it round the heating circuit

Flow only gets hot to diverter.
