do you think that heat pumps “cook the ground” or “cook the air” too? the whole point is to transfer rather than generate heat

The river doesn’t care whether the heat comes from electrical resistance, chemical reaction or the inside of a building. Heat is heat. How that amount of heat will affect the ecology of the river I do not know. I am unfamiliar how how the cooling capacity of the proposed system relates to the hydrology of Paris.
