How is it that a machine (like a heat pump) can consume 1kw of power and produce an amount greater than that of heat? What am I misunderstanding?

it isn’t taking in energy to *produce* heat, it’s taking in energy to *move* heat.
the extra energy is coming from somewhere else. for a house, it’s the air outside. a heatpump sucks energy from the air, making it even colder than it already is, then dumps that heat energy inside where it’s warm.
air conditioning is also a heat pump. it takes heat from inside your cool house and dumps it outside in the hot weather. fighting entropy like that takes energy, but we can do it.
