Fortunately the inlet temperature of water is measured and this

But he effect is negligible- and not on the side of Pin- it is at Pout.
No, not Pout. The heat from the pump shows up past Pout, at the place
where the water stops moving. That would be either in your drain pipe,
or -- if you recycle the water -- in the reservoir tank. As long as the
water is moving at the same speed as it did when it left the pump, the
energy has not yet converted to heat.
