2022/1/15 · If the pumping head of the boiler is an order of magnitude lower than the B-pump branch that may not matter very much- pump B will spin very slowly in reverse, and the flow will be quite limited. If it's a higher head boiler there could be enough flow for measurable amounts of heat to be emitted from the B-zone baseboard.
