All 4 zones are getting flow whenever one, two or three other zones are calling for heat. Each zone has it's own pump. The issue is, the WM has an internal pump that runs whenever a zone circ. pump...

Will the boiler pump suffice to circulate the indirect flow, or is the additional pump mounted in line on the supply side going to the indirect as was illustrated needed?
