T-stats represent a fairly large restriction to flow, even when open fully, which loads the water pump.
I believe this whole premise to be incorrect.

When you reduce volume pumped by restriction, the load on the pump gets EASIER, not harder.

Example? Take a hairdryer and turn it on. Note the speed. Now block the flow completely. It speeds up! It wouldn't speed up unless the load was reduced.
