Operating a digger to move dirt isn't pumping heat either, if we're listing project components that aren't pumping heat.

I'm guessing you caught but ignored the part that is moving heat?

One can move heat from one place to another by moving a fluid. This is not a heat pump, even if the fluid is pumped.

A heat pump is a specific kind of thermodynamic device that moves heat energy from lower to higher temperature.

The system that is described in the OP link does not use a heat pump. Electrical energy is used to make heat, but it does so with a resistive heater, not a heat pump.
